NFSI Exam — Questions and Answers

Question 1: A fire crew that holds each member accountable for their responsibilities is MOST likely to experience:

Increased interpersonal conflict due to high expectations
Higher turnover as firefighters seek less demanding environments
Stronger trust, reliability, and overall team performance (Correct answer)
Reduced morale because of constant scrutiny

Correct answer: Stronger trust, reliability, and overall team performance

Accountability within a team builds mutual trust, as each member can rely on others to fulfill their responsibilities consistently.

Question 2: A firefighter reports that they frequently re-experience a traumatic incident through intrusive flashbacks weeks after the event. This most likely indicates:

Normal adjustment that will resolve without intervention
Malingering to avoid duty
Possible Post-Traumatic Stress Disorder (PTSD) symptoms requiring professional evaluation (Correct answer)
A side effect of protective equipment use

Correct answer: Possible Post-Traumatic Stress Disorder (PTSD) symptoms requiring professional evaluation

Persistent intrusive flashbacks beyond a few weeks following trauma are a hallmark symptom of PTSD and warrant professional mental health evaluation.

Question 3: A hose delivers 125 gallons per minute. How many gallons are delivered in 8 minutes?

1,000 gallons (Correct answer)
1,125 gallons
750 gallons
875 gallons

Correct answer: 1,000 gallons

125 × 8 = 1,000 gallons.

Question 4: A hydraulic rescue tool generates 10,000 pounds of force through a cylinder with a 2-square-inch piston. The hydraulic pressure in the system is:

5,000 psi (Correct answer)
20,000 psi
200 psi
2,000 psi

Correct answer: 5,000 psi

Pressure = Force ÷ Area = 10,000 lbs ÷ 2 in² = 5,000 psi.

Question 5: A firefighter must write a narrative for an incident report. The following sentences describe the events. What is the correct chronological and logical order for these sentences? 1. Upon arrival, crews observed light smoke coming from a second-floor window of a two-story residence. 2. Engine 1 was dispatched at 15:30 to a report of a possible structure fire. 3. The fire was declared under control at 15:55, and overhaul operations began. 4. A 1.75-inch attack line was advanced to the second floor, where a small fire in a bedroom was quickly extinguished.

2, 4, 1, 3
1, 4, 2, 3
2, 1, 4, 3 (Correct answer)
1, 2, 4, 3

Correct answer: 2, 1, 4, 3

Incident reports should tell a story in chronological order. The correct sequence is: Dispatch (2), Arrival Conditions (1), Actions Taken (4), and Outcome/Conclusion (3). This order logically presents the events as they unfolded.

Question 6: Which analogy is correct? Smoke is to fire as _____ is to injury.

Hospital
Pain (Correct answer)
Bandage
Blood

Correct answer: Pain

Pain is a symptom of injury just as smoke is a symptom/byproduct of fire.

Question 7: All certified firefighters are required to complete annual hazardous materials training. Firefighter Miller just completed this year's training. Therefore, Firefighter Miller:

is now an expert in all hazardous materials.
is certified for hazardous materials incidents.
does not need to attend any other training this year.
is a certified firefighter. (Correct answer)

Correct answer: is a certified firefighter.

This question tests deductive reasoning, which involves applying a general rule to a specific case to reach a logical conclusion. The primary rule is that 'All certified firefighters' must complete the training. The fact that Firefighter Miller completed the training logically supports the conclusion that he is a certified firefighter. The other options make assumptions that are not supported by the premises.

Question 8: Which statement BEST reflects a healthy team motivation mindset in the fire service?

Crew members are motivated by shared purpose, mutual support, and pride in their unit (Correct answer)
Motivation is solely the responsibility of the company officer, not individual crew members
Firefighters are most productive when they work independently to avoid reliance on others
The best firefighters are motivated by competition and outperforming their peers

Correct answer: Crew members are motivated by shared purpose, mutual support, and pride in their unit

Healthy team motivation in fire service stems from shared mission, mutual accountability, and collective pride in the crew's work.

Question 9: A firefighter discovers that a fellow crew member has falsified an inspection report. What is the most appropriate course of action?

Cover for the crew member since team loyalty is paramount
Ignore it to avoid conflict within the crew
Confront the crew member publicly to deter future misconduct
Report the falsification to a supervisor through proper channels (Correct answer)

Correct answer: Report the falsification to a supervisor through proper channels

Reporting falsified records through proper channels upholds public safety and departmental integrity, which are core professional obligations.

Question 10: A firefighter is conducting a routine inspection of a commercial kitchen. Which of the following observations demonstrates the highest degree of problem sensitivity?

The ventilation hood has a small amount of grease buildup that is cool to the touch.
The floors are wet from recent mopping.
A fire extinguisher's tag shows it was last serviced 13 months ago. (Correct answer)
An employee is cooking with a large, controlled flame on a gas stove.

Correct answer: A fire extinguisher's tag shows it was last serviced 13 months ago.

Problem sensitivity is the ability to recognize that a problem exists or is likely to develop. A fire extinguisher being out of its service date by a month is a direct violation of safety code and a clear problem that could have severe consequences in an emergency. The other options describe normal or minor conditions, whereas the expired extinguisher represents an immediate and actionable safety hazard.

Question 11: Which of the following types of fire extinguishers is typically suitable for use on fires involving combustible materials such as wood, paper, and cloth?

Class B
Class C
Class D
Class A (Correct answer)

Correct answer: Class A

Explanation: Class A fire extinguishers are designed to extinguish fires involving ordinary combustible materials such as wood, paper, cloth, and some plastics. They typically contain water or a dry chemical agent such as monoammonium phosphate.

Question 12: Fire department regulations require that after any use, fire hoses must be washed, dried, and re-racked on the engine. An engine returns from a minor car fire where a short section of hose was used to extinguish the engine compartment. The crew is nearing the end of their 24-hour shift and is fatigued. What is the MOST logical reason for this regulation?

To ensure the fire apparatus always looks clean and professional for the public.
To ensure the hose is clean, undamaged, and ready for immediate reuse at the next emergency. (Correct answer)
To provide a routine task that helps firefighters decompress after an incident.
To prevent dirt and grime from building up in the station's hose storage area.

Correct answer: To ensure the hose is clean, undamaged, and ready for immediate reuse at the next emergency.

This question assesses the ability to reason the purpose behind a rule. The primary goal of all equipment maintenance in the fire service is to ensure operational readiness and safety. [5] While cleanliness is a byproduct, the critical reason for immediately cleaning and inspecting the hose is to ensure it is free of damage (e.g., from heat, chemicals, or debris from the car fire) and packed correctly, making it reliable and ready for deployment at a moment's notice for the next, potentially more critical, incident.

Question 13: When a firefighter disagrees with a department policy, the most professional and ethical course of action is to:

Disregard the policy when the opportunity arises
Follow the policy while pursuing change through official grievance or suggestion channels (Correct answer)
Convince fellow crew members to collectively refuse compliance
Complain to the public to generate pressure for change

Correct answer: Follow the policy while pursuing change through official grievance or suggestion channels

Complying with existing policy while using proper internal channels to advocate for change upholds organizational order and professional integrity.

Question 14: A fire investigation scene preservation rule states: (1) photograph scene before anything is moved, (2) identify point of origin, (3) collect evidence samples, (4) allow salvage operations. The rule: step 4 only after steps 1, 2, and 3 are complete. An investigator skips step 2 and goes to 3. What is wrong?

Photography must follow evidence collection
Step 3 cannot occur before step 1
Point of origin must be identified before evidence is collected (Correct answer)
Salvage operations were started too early

Correct answer: Point of origin must be identified before evidence is collected

The protocol requires point-of-origin identification before collecting samples so that evidence context is preserved.

Question 15: Two firefighters are preparing to raise a 24-foot extension ladder to a second-story window using a beam raise. What is the correct order of the following general actions? 1. One firefighter 'foots' the ladder to prevent it from slipping while the other raises it. 2. The ladder is carried on its beam to the target location. 3. The halyard is untied and the fly section is extended to the proper height. 4. The ladder is raised from the ground to a vertical position against the building.

2, 4, 1, 3 (Correct answer)
4, 2, 1, 3
2, 1, 4, 3
1, 2, 4, 3

Correct answer: 2, 4, 1, 3

The logical flow of operations is to first transport the ladder to its point of use (2). From there, it is pivoted and raised into a vertical position against the structure (4). For safety, one firefighter must then foot the ladder at its base to prevent it from kicking out (1). Once the ladder is secure, the fly section can be safely extended to the desired height (3).

Question 16: A manual states: 'Thermal imaging cameras (TIC) detect heat signatures but cannot see through walls.' A firefighter using a TIC sees no heat signatures in a room and concludes the room is clear of victims. This conclusion is:

Reliable because TICs are highly accurate
Correct as long as the TIC is properly calibrated
Only invalid in concrete structures
Unreliable if victims may be in an adjacent room behind a wall (Correct answer)

Correct answer: Unreliable if victims may be in an adjacent room behind a wall

Since TICs cannot see through walls, a clear reading in one room says nothing about heat signatures in adjacent spaces.

Question 17: A pattern shows: Circle, Triangle, Square, Circle, Triangle, Square, Circle, ___. What comes next?

Pentagon
Triangle (Correct answer)
Circle
Square

Correct answer: Triangle

The pattern repeats every 3 shapes: Circle, Triangle, Square — so after Circle comes Triangle.

Question 18: A block and tackle system has 4 rope segments supporting the load. If the load weighs 400 pounds, approximately how much force must the firefighter apply to lift it (ignoring friction)?

100 lbs (Correct answer)
400 lbs
50 lbs
200 lbs

Correct answer: 100 lbs

With 4 supporting rope segments, the mechanical advantage is 4, so the required force is 400 ÷ 4 = 100 pounds.

Question 19: A firefighter needs to determine which direction a gear will turn if the driving gear rotates clockwise. If two gears mesh directly, the driven gear will turn:

It depends on gear size
Counterclockwise (Correct answer)
The same direction as the driver
Clockwise

Correct answer: Counterclockwise

When two gears mesh directly, they rotate in opposite directions, so a clockwise driver causes a counterclockwise driven gear.

Question 20: Read the following passage and answer the question that follows. 'Firefighters must regularly inspect and maintain their Self-Contained Breathing Apparatus (SCBA). This process includes checking the cylinder pressure to ensure it is full, examining the facepiece for any signs of damage or deterioration, and performing a function test on the regulator and alarms. All inspection activities must be meticulously documented in the station's equipment logbook. Failure to properly maintain this critical piece of equipment can lead to catastrophic failure during an emergency.' Based on the passage, which of the following is the MOST accurate statement?

Proper documentation of SCBA inspections is as crucial as the physical inspection itself. (Correct answer)
A visual check of the facepiece is sufficient for the entire inspection process.
SCBA maintenance is optional for firefighters who are not assigned to hazardous material incidents.
SCBA equipment is designed to function perfectly without regular maintenance checks.

Correct answer: Proper documentation of SCBA inspections is as crucial as the physical inspection itself.

The passage explicitly states that all inspection activities 'must be meticulously documented in the station's equipment logbook,' highlighting the importance of documentation alongside the physical checks. The other options are directly contradicted by the text, which emphasizes that maintenance is regular, involves multiple steps beyond a visual check, and is critical to prevent equipment failure.

Question 21: After a particularly traumatic call, a crew member appears distressed but insists he is fine. Your most appropriate response is:

Mandate he speak with a counselor immediately
Accept his word and move on to avoid prying
Announce to the crew that he needs support to encourage them to help
Check in privately, share resources, and monitor over the following days (Correct answer)

Correct answer: Check in privately, share resources, and monitor over the following days

A supportive, private approach respects the individual while ensuring access to resources and ongoing monitoring for behavioral changes.

Question 22: If a fire engine travels 4 miles in 6 minutes, what is its speed in miles per hour?

45 mph
40 mph (Correct answer)
50 mph
35 mph

Correct answer: 40 mph

4 miles / 6 minutes × 60 minutes/hour = 40 mph.

Question 23: Three containers of water weigh 15, 22, and 33 pounds. A firefighter must carry all three in one trip using two hands. The most balanced way is to hold the 22-pound container in one hand and which combination in the other?

15 lbs only (Correct answer)
None — impossible to balance
15 + 33 lbs
33 lbs only

Correct answer: 15 lbs only

Balancing 22 lbs in one hand against 15 lbs in the other is the closest equal split; holding 33 lbs would be 33 vs. 37 lbs, which is slightly less balanced.

Question 24: You arrive at the scene of a single-vehicle accident. A car has hit a utility pole. The driver is conscious but appears disoriented. The utility pole is cracked, and the power lines are sagging but not touching the ground. Which of the following is the most immediate potential problem to be recognized?

The vehicle is likely totaled, creating a financial problem for the owner.
The cracked utility pole could fall and cause further damage.
The sagging power lines could be energized and pose an electrocution risk. (Correct answer)
The driver may have a medical condition that caused the crash.

Correct answer: The sagging power lines could be energized and pose an electrocution risk.

This scenario tests problem sensitivity, specifically the ability to identify the most critical and immediate hazard. While all the options are potential issues, the risk of electrocution from energized, sagging power lines is the most immediate and life-threatening hazard to the victim and the responders. Securing the scene from this electrical hazard is the top priority before any other action can be taken safely.

Question 25: Which of the following best defines 'Problem Sensitivity' in the context of firefighting?

The ability to recognize or identify that a problem exists or is likely to develop. (Correct answer)
The ability to feel empathy for victims at an emergency scene.
The ability to remain calm and insensitive to high-stress situations.
The ability to solve complex logistical problems under pressure.

Correct answer: The ability to recognize or identify that a problem exists or is likely to develop.

This is a direct knowledge question defining a key term. Problem Sensitivity on the NFSI is the ability to recognize potential hazards or notice when something is wrong in a given situation. It is about identifying problems, not necessarily solving them or managing emotions, although those are also important skills.

Question 26: Select the word, phrase, or punctuation mark that correctly completes the sentence: Firefighters show up at the scene of a fire or emergency and ______ on advanced tools and equipment to handle the situation.

relay
rely (Correct answer)
linked
relly

Correct answer: rely

Explanation: The correct spelling of the word is "rely." "Relay" is a word of completely different meaning while "relly" and "relye" are non-existing words.

Question 27: Which word is the antonym of 'hazardous'?

Benign (Correct answer)
Volatile
Toxic
Perilous

Correct answer: Benign

'Benign' means harmless or not dangerous, making it the antonym of hazardous.

Question 28: Which of the following is a primary indicator of integrity in a firefighter?

The ability to lift a certain amount of weight.
Having the most knowledge about department standard operating procedures.
Consistently being honest and taking responsibility for one's actions, even when a mistake is made. (Correct answer)
Always being the first to volunteer for a dangerous task.

Correct answer: Consistently being honest and taking responsibility for one's actions, even when a mistake is made.

Integrity is defined by moral and ethical principles, including honesty and accountability. A firefighter with integrity does the right thing, admits to errors, and can be trusted by their crew and the public. The other options relate to physical fitness, courage, or knowledge, but not directly to the core concept of integrity.

Question 29: A community member approaches you in the station and makes a complaint about how a recent fire response was handled. You were not involved in that call. You should:

Dismiss the complaint since it didn't involve you
Agree with the community member to de-escalate tension
Listen respectfully and direct them to the appropriate department contact (Correct answer)
Criticize your colleagues to show you would have done better

Correct answer: Listen respectfully and direct them to the appropriate department contact

Firefighters represent the department even when off-call; listening respectfully and directing concerns appropriately maintains public trust.

Question 30: What is the purpose of an ethics policy in a fire department?

To limit the authority of supervisors over crew members
To identify and punish firefighters who underperform
To create additional paperwork for personnel
To establish clear standards that guide professional behavior and decision-making (Correct answer)

Correct answer: To establish clear standards that guide professional behavior and decision-making

Ethics policies provide clear behavioral standards that help all personnel make sound decisions and maintain public trust in the department.

Question 31: A fire station receives four simultaneous alarms. Rule: respond to alarms in order of (1) confirmed structure fire, (2) gas leak with ignition risk, (3) vehicle accident with injuries, (4) trash fire. The calls are: Call A=gas leak, Call B=trash fire, Call C=structure fire, Call D=vehicle accident. Correct dispatch order:

C, A, D, B (Correct answer)
D, C, A, B
A, C, D, B
C, D, A, B

Correct answer: C, A, D, B

Structure fire (C) first, gas leak with ignition risk (A) second, vehicle accident (D) third, trash fire (B) last per the priority rule.

Question 32: Which action best demonstrates integrity in the fire service?

Doing the right thing even when no one is observing (Correct answer)
Completing tasks only when a supervisor is watching
Agreeing with supervisors to avoid conflict
Prioritizing crew comfort over completing difficult tasks

Correct answer: Doing the right thing even when no one is observing

Integrity means consistently doing the right thing regardless of whether anyone is watching, which is foundational to public trust in firefighters.

Question 33: A department bulletin explains that peer support resources are available 24/7 for firefighters experiencing critical incident stress. After a traumatic call, a firefighter notices a colleague seems withdrawn and stops eating at the firehouse. The most appropriate response is to:

Casually check in with the colleague and mention peer support is available (Correct answer)
Report the colleague to the captain for a performance review
Ignore it — personal issues are private matters
Immediately mandate the colleague attend counseling

Correct answer: Casually check in with the colleague and mention peer support is available

A low-pressure check-in that mentions available peer support is the appropriate first step, respecting the colleague's dignity while opening the door to help.

Question 34: A fire department has a policy that states: 'SCBA shall be worn by all personnel entering an atmosphere that is or may become hazardous.' During a response to a dumpster fire, a firefighter observes only light smoke that is being carried away by the wind. The captain orders the firefighter to extinguish the fire without wearing an SCBA. What is the core problem in this scenario?

The captain's order directly contradicts a critical safety policy. (Correct answer)
The firefighter is questioning a direct order from a superior officer.
The policy is too restrictive for minor incidents like dumpster fires.
The smoke is too light to be considered a hazardous atmosphere.

Correct answer: The captain's order directly contradicts a critical safety policy.

Problem sensitivity is the ability to recognize when something is wrong or is likely to go wrong. [1, 5] The core problem is that the captain's order violates a clear departmental safety policy. The policy states that SCBA must be worn in atmospheres that 'may become hazardous.' A fire, even a small one, can change conditions rapidly, and the contents of a dumpster are unknown, potentially producing toxic smoke. The order creates an unnecessary safety risk and undermines established procedure.

Question 35: After a traumatic call, a firefighter returns to the station and becomes withdrawn and irritable. This behavior most likely indicates:

Poor character and professionalism
A normal acute stress response that may need support (Correct answer)
Physical injury that was not disclosed
Willful insubordination that should be reported

Correct answer: A normal acute stress response that may need support

Withdrawal and irritability following a traumatic event are common acute stress responses and signal a need for peer or professional support.

Question 36: A passage explains that post-incident critiques are conducted to improve future performance, not to assign blame. A crew member dominates the critique by blaming a colleague for a tactical error. The best response from the facilitator is to:

End the critique early to protect the blamed firefighter
Ask the blamed firefighter to leave the room
Redirect the discussion to what the crew as a whole can do differently (Correct answer)
Allow the critique to continue since all perspectives are valid

Correct answer: Redirect the discussion to what the crew as a whole can do differently

Redirecting toward collective improvement keeps the critique constructive and aligned with its no-blame purpose.

Question 37: A building has an occupancy load of 450 people. Fire code requires 1 exit per 150 occupants. How many exits must the building have?

3 (Correct answer)
5
4
2

Correct answer: 3

450 ÷ 150 = 3 exits required.

Question 38: A fire station receives calls at an average of 18 calls per day. Approximately how many calls does it receive in a 30-day month?

540 calls (Correct answer)
560 calls
520 calls
480 calls

Correct answer: 540 calls

18 × 30 = 540 calls.

Question 39: A firefighter posts a photo on social media showing the interior of a home where the crew responded to a fire. Which concern is most significant?

The photo may not show the crew in a flattering light
The photo might reveal department equipment specifications
It could violate the privacy of the homeowner and expose the department to liability (Correct answer)
Other firefighters might take similar photos and clog the internet

Correct answer: It could violate the privacy of the homeowner and expose the department to liability

Posting images from emergency scenes can violate victims' privacy, breach confidentiality, and create significant legal liability for the firefighter and department.

Question 40: A firefighter overhears colleagues making discriminatory remarks about a new recruit. What is the most professional response?

Address the behavior or report it to a supervisor if it continues (Correct answer)
Join in to fit in with the crew
Tell the new recruit to toughen up
Ignore it since it is just locker room talk

Correct answer: Address the behavior or report it to a supervisor if it continues

Addressing or reporting discriminatory behavior fulfills the professional obligation to maintain a respectful and inclusive workplace.

Question 41: You are exhausted after a long shift but are asked to stay for mandatory overtime. Accepting the overtime may affect your ability to perform safely. You should:

Accept without disclosing your fatigue level
Accept but reduce your participation in physical tasks without telling anyone
Inform your supervisor honestly about your fatigue and follow department protocol (Correct answer)
Refuse and leave immediately without explanation

Correct answer: Inform your supervisor honestly about your fatigue and follow department protocol

Honest disclosure of fatigue-related fitness for duty allows supervisors to make informed staffing decisions while maintaining safety standards.

Question 42: Which sentence is grammatically correct?

The captain, along with his crew, was evacuated. (Correct answer)
The captain along with his crew, was evacuated.
The captain along with his crew were evacuated.
The captain, along with his crew, were evacuated.

Correct answer: The captain, along with his crew, was evacuated.

'The captain' is the singular subject, so the verb must be 'was,' not 'were.'

Question 43: What does 'accountability' mean in the context of fire department professional conduct?

Filing accurate payroll and overtime records
Ensuring every firefighter passes annual fitness tests
Tracking inventory of equipment after every call
Taking personal responsibility for one's actions and decisions (Correct answer)

Correct answer: Taking personal responsibility for one's actions and decisions

Accountability in the fire service means owning one's decisions and actions, including mistakes, to support safety and organizational trust.

Question 44: What is the primary reason firefighters are expected to maintain confidentiality regarding sensitive incident information?

To protect the privacy and dignity of individuals involved (Correct answer)
To protect departmental reputation from negative press
To prevent other agencies from interfering
To avoid paperwork and legal complications

Correct answer: To protect the privacy and dignity of individuals involved

Confidentiality protects the privacy, dignity, and legal rights of victims and individuals involved in emergency incidents.

Question 45: A firefighter's shift is 24 hours. She works 10 shifts per month. How many hours does she work per month?

240 hours (Correct answer)
260 hours
200 hours
220 hours

Correct answer: 240 hours

24 × 10 = 240 hours per month.

Question 46: A fire department has a policy stating: 'During a structure fire, if visibility is less than two feet due to smoke, a thermal imaging camera (TIC) must be used for all interior searches.' A crew enters a burning building and encounters dense smoke, reducing visibility to approximately one foot. Which of the following actions is the correct application of this rule?

The crew should immediately exit the building to wait for the smoke to clear.
The crew must use a thermal imaging camera to conduct their search. (Correct answer)
The policy does not apply if they are searching for a known victim.
The crew can proceed with the search if they use a hand light and move slowly.

Correct answer: The crew must use a thermal imaging camera to conduct their search.

This is a deductive reasoning question that requires applying a specific rule to a situation. The policy provides a clear rule based on a specific condition (visibility less than two feet). The scenario explicitly states visibility is one foot, which meets the condition. Therefore, the only correct action according to the rule is to use a TIC.

Question 47: A study guide passage states that NFSI scores are used alongside other hiring criteria and no single score is automatically disqualifying. A candidate who scores below average on one section should:

Request the section be removed from their assessment
Assume they will not be hired and stop preparing
Recognize that strong performance in other areas can offset the lower score (Correct answer)
Withdraw their application immediately

Correct answer: Recognize that strong performance in other areas can offset the lower score

Because NFSI scores are evaluated holistically alongside other criteria, strength in other sections can compensate for a weaker section.

Question 48: Using the rule 'decontaminate in order from most to least contaminated areas of the body,' a firefighter exposed to a hazmat spill must decon in which sequence? Head and neck (H), hands and forearms (F), torso (T), boots and legs (B).

H, B, F, T
H, F, T, B
B, T, F, H
F, H, B, T (Correct answer)

Correct answer: F, H, B, T

Hands and forearms had direct contact first, then head/neck, boots/legs next, and torso last as it was most shielded.

Question 49: A passage describes the 'two-in, two-out' rule requiring that when two firefighters enter an immediately dangerous to life or health (IDLH) atmosphere, two others must stand by outside ready to rescue. A crew of four arrives and all four want to enter. Under this rule:

All four may enter if a fifth unit is en route
The rule only applies to hazmat incidents
All four may enter if they stay together
Two may enter while two remain outside on standby (Correct answer)

Correct answer: Two may enter while two remain outside on standby

The two-in, two-out rule requires two responders to remain outside in a ready-to-rescue posture whenever two enter an IDLH atmosphere.

Question 50: You are a firefighter writing an incident report. Which of the following statements is the most professional and objective for the report?

The homeowner was freaking out and wouldn't stop yelling about some animal.
We had to deal with a very emotional homeowner who was worried about a pet.
The homeowner appeared to be in distress and stated that a pet was still inside the residence. (Correct answer)
The hysterical homeowner was screaming about her cat being inside.

Correct answer: The homeowner appeared to be in distress and stated that a pet was still inside the residence.

This statement is the most professional because it uses objective language ('appeared to be in distress', 'stated that') to describe the situation without passing judgment or using subjective, emotional terms like 'hysterical' or 'freaking out'.

Question 51: If a 1,500-gallon tank is 35% full, how many more gallons are needed to fill it completely?

975 (Correct answer)
850
525
1,100

Correct answer: 975

35% of 1,500 = 525 gallons already in the tank; 1,500 − 525 = 975 gallons needed.

Question 52: A dispatcher receives the following calls simultaneously: (1) car fire on highway, (2) residential structure fire with reported entrapment, (3) dumpster fire behind a restaurant, (4) smoke investigation at a school. Using the rule 'prioritize life safety over property, and occupied structures over unoccupied,' which is the correct dispatch order?

4, 2, 1, 3
2, 4, 1, 3 (Correct answer)
2, 1, 4, 3
1, 2, 3, 4

Correct answer: 2, 4, 1, 3

Entrapment (life safety) ranks first, occupied school second, car fire (property/unoccupied) third, and unattended dumpster last.

Question 53: During a promotional exam, a candidate notices the test administrator left answer materials unattended. The most ethical action is to:

Quickly look at the answers before the administrator returns
Tell a friend about the opportunity but not look yourself
Wait and see if other candidates notice first
Alert the administrator immediately about the security breach (Correct answer)

Correct answer: Alert the administrator immediately about the security breach

Alerting the administrator demonstrates integrity and upholds the fairness of the selection process for all candidates.

Question 54: A fire crew is dispatched to a report of a strange odor in a residential home. Upon arrival, they find a homeowner who states the smell is like rotten eggs and is coming from the basement. The crew does not smell anything on the first floor. Based on this information, which of the following is the MOST logical deduction?

The odor is characteristic of a natural gas leak, which is a significant and immediate hazard. (Correct answer)
The problem is most likely a sewer gas issue from a dry drain trap.
The furnace is likely malfunctioning and should be turned off for service.
The homeowner is likely mistaken, and there is no real hazard.

Correct answer: The odor is characteristic of a natural gas leak, which is a significant and immediate hazard.

Deductive reasoning involves applying a general rule to a specific situation. [3] The odor of rotten eggs (mercaptan) is a well-known additive to natural gas to alert people to a leak. [1] A firefighter should immediately deduce that the smell indicates a potential gas leak, which is a serious, explosive hazard requiring immediate action, such as evacuating the structure and notifying the gas company.

Question 55: What is the primary hazard associated with a backdraft condition?

Explosive ignition when oxygen is suddenly introduced to an oxygen-starved fire (Correct answer)
Structural collapse caused by prolonged heat exposure
Rapid flame spread along a smoke-filled ceiling
Toxic gas buildup that asphyxiates occupants

Correct answer: Explosive ignition when oxygen is suddenly introduced to an oxygen-starved fire

Backdraft is a deflagration explosion triggered when oxygen is introduced to a superheated, oxygen-depleted compartment containing unburned combustible gases.

Question 56: While conducting a commercial building inspection, a firefighter notices that several emergency exit signs are not illuminated. The business owner states they are scheduled to be repaired next week. Considering the principle of problem sensitivity, what is the firefighter's MOST appropriate immediate action?

Accept the owner's explanation but advise them to expedite the repairs.
Immediately notify the on-duty fire marshal or inspector about a significant life safety hazard. (Correct answer)
Note the deficiency in the inspection report and follow up in a week.
Tell the owner to close the business until the signs are repaired.

Correct answer: Immediately notify the on-duty fire marshal or inspector about a significant life safety hazard.

Problem sensitivity involves recognizing a potential problem and understanding its immediate implications. [1, 5] Non-illuminated exit signs are a critical life safety hazard that compromises the ability of occupants to escape in an emergency. The most appropriate action is to treat this as a significant, immediate risk and escalate it to the authority responsible for enforcement, which is typically the fire marshal or inspector.

Question 57: A firefighter visualizes a 3D cube and mentally rotates it 90 degrees to the right. The face that was on top is now facing:

Down
Left
Right (Correct answer)
The same direction

Correct answer: Right

Rotating a cube 90 degrees to the right causes the top face to rotate to face the right side.

Question 58: You are the most experienced person on shift but not the designated officer. A situation arises where the officer is temporarily unavailable. You should:

Defer to the least experienced person to build their confidence
Take full command of all decisions until the officer returns
Manage immediate safety needs and notify leadership as soon as possible (Correct answer)
Wait for the officer to return before taking any action

Correct answer: Manage immediate safety needs and notify leadership as soon as possible

Acting on immediate safety needs while promptly notifying leadership balances emergency responsiveness with proper chain of command.

Question 59: A mayday rescue protocol assigns roles in this sequence: (1) IC designates Rapid Intervention Team leader, (2) RIT leader briefs team on downed firefighter's last known location, (3) RIT activates and enters structure, (4) IC broadcasts mayday acknowledgment to all units. The rule: step 4 must occur before step 1. A new IC broadcasts acknowledgment after designating the RIT leader. What error occurred?

No error occurred; order is flexible
The RIT entered without a briefing
IC acknowledged the mayday out of sequence after designating the RIT leader (Correct answer)
The RIT leader briefed before IC acknowledged

Correct answer: IC acknowledged the mayday out of sequence after designating the RIT leader

Per the protocol, IC must broadcast mayday acknowledgment before designating the RIT leader, so doing it after violates the sequence.

Question 60: A fire engine's water tank has a capacity of 750 gallons. If water weighs approximately 8.34 pounds per gallon, what is the total weight of the water in the tank when it is completely full?

8,340 lbs
6,255 lbs (Correct answer)
5,455 lbs
7,500 lbs

Correct answer: 6,255 lbs

To find the total weight of the water, multiply the volume of the water in gallons by the weight of one gallon: 750 gallons * 8.34 lbs/gallon = 6,255 lbs.

Question 61: Which of the following is a common barrier to effective communication on an emergency scene that can be directly controlled by the speaker?

A malfunctioning radio system.
Loud background noise from sirens and equipment.
Using overly technical jargon or unfamiliar acronyms. (Correct answer)
Receivers who are distracted by other tasks.

Correct answer: Using overly technical jargon or unfamiliar acronyms.

A speaker has direct control over the words they choose. Using jargon or acronyms that others may not understand creates a communication barrier. While background noise, equipment failure, and distracted listeners are also barriers, the speaker cannot directly control them; they can only attempt to mitigate their effects. They can, however, choose to use plain, clear language.

Question 62: A MAYDAY protocol requires: (1) activate PASS device, (2) transmit MAYDAY on radio, (3) conserve air, (4) attempt self-rescue. The rule states self-rescue is attempted before conserving air only if exit is confirmed visible. Exit is NOT visible. Which is the correct order?

2, 1, 3, 4 (Correct answer)
1, 2, 4, 3
2, 1, 4, 3
4, 1, 2, 3

Correct answer: 2, 1, 3, 4

When exit is not visible, transmit MAYDAY, activate PASS, conserve air, then attempt self-rescue if possible.

Question 63: When a fire crew successfully completes a challenging incident, the company officer MOST effectively reinforces team motivation by:

Acknowledging collective effort and identifying specific team behaviors that led to success (Correct answer)
Waiting for the formal performance review cycle to provide feedback
Briefly noting the success and moving directly to the next assignment without discussion
Highlighting the performance of the single best-performing individual

Correct answer: Acknowledging collective effort and identifying specific team behaviors that led to success

Recognizing specific collective behaviors reinforces the actions that led to success, building motivation and team identity.

Question 64: During a rescue, your breathing apparatus gives a low-air warning with several minutes remaining in the operation. You should:

Continue silently and alert command only upon exit
Ignore it and finish the task since you have time left
Remove the mask to conserve air
Immediately notify your partner and begin exiting while completing final steps if safe (Correct answer)

Correct answer: Immediately notify your partner and begin exiting while completing final steps if safe

Low-air warnings require immediate partner notification and an exit plan because conditions can deteriorate faster than expected.

Question 65: A firefighter is tasked with properly donning their Self-Contained Breathing Apparatus (SCBA). Arrange the following critical steps into the correct sequence. 1. Don the facepiece and check for a proper seal. 2. Fully open the cylinder valve and check the gauge readings. 3. Don the backpack assembly and tighten the straps. 4. Connect the regulator to the facepiece and begin breathing.

2, 3, 1, 4 (Correct answer)
1, 3, 2, 4
2, 1, 3, 4
3, 2, 4, 1

Correct answer: 2, 3, 1, 4

The correct and safest procedure is to first ensure the air supply is on and functioning by opening the valve and checking gauges (2). Next, the firefighter puts on the main harness assembly (3). Then, the facepiece is donned and a negative or positive pressure seal check is performed to ensure it is airtight (1). The final step is to connect the regulator and confirm the apparatus is delivering air (4).

Question 66: A truck travels 18 miles to a fire and returns the same distance. If it averages 36 mph for the entire trip, how long did the round trip take?

30 minutes (Correct answer)
15 minutes
60 minutes
45 minutes

Correct answer: 30 minutes

Total distance = 36 miles; 36 ÷ 36 = 1 hour = 60 minutes — wait, 36 miles ÷ 36 mph = 1 hour; correct answer 60 minutes.

Question 67: Which of the following best describes a conflict of interest for a firefighter?

Feeling stressed during a multi-alarm fire
Disagreeing with a supervisor about tactics
Preferring one type of equipment over another
Having a personal financial stake in a business your station inspects (Correct answer)

Correct answer: Having a personal financial stake in a business your station inspects

A conflict of interest exists when a personal financial or personal interest could improperly influence official duties such as inspections.

Question 68: A sequence reads: 3, 6, 12, 24, ___. What is the next number?

60
42
36
48 (Correct answer)

Correct answer: 48

Each number is doubled: 24 × 2 = 48.

Question 69: A training document states: 'When reading a passage under timed conditions, identify the main idea first, then supporting details.' A firefighter reads a hazmat placard description. The first thing they should identify is:

The specific chemical name
The primary hazard class of the material (Correct answer)
The emergency contact number
The UN number

Correct answer: The primary hazard class of the material

The primary hazard class (flammable, corrosive, toxic, etc.) represents the 'main idea' of a placard and guides the initial response approach.

Question 70: A report states injuries occurred at 0230, 0415, 0820, and 1310 hours. How many of these times are in the afternoon (PM)?

1 (Correct answer)
3
0
2

Correct answer: 1

Only 1310 (1:10 PM) falls in the afternoon; the others are early morning.

Question 71: What does it mean to demonstrate 'collective efficacy' as part of a fire crew?

Competing with other crews to demonstrate superior capability
Deferring all decisions to the most experienced member
Believing that you personally can outperform your teammates
Trusting that the team as a whole can successfully handle challenging tasks (Correct answer)

Correct answer: Trusting that the team as a whole can successfully handle challenging tasks

Collective efficacy is the shared belief in a team's ability to perform effectively, which boosts coordination and resilience under pressure.

Question 72: A firefighter looks at a mirror image of a map. In the mirror, the exit marked on the east side of the building appears to be on which side?

South
East
West (Correct answer)
North

Correct answer: West

A mirror reverses left and right (east and west), so what appears east in reality appears west in the mirror.

Question 73: Which simple machine is most directly used when a firefighter operates a pry bar to open a door?

Wheel and axle
Lever (Correct answer)
Inclined plane
Pulley

Correct answer: Lever

A pry bar functions as a lever, with the fulcrum point against the door frame multiplying the applied force.

Question 74: You are dispatched to multiple simultaneous emergencies in one shift. What mental strategy best sustains performance?

Rely solely on adrenaline to maintain energy
Remind yourself of past failures to stay alert
Treat each call as independent and apply full focus to the one at hand (Correct answer)
Mentally rehearse every possible outcome before arrival at each scene

Correct answer: Treat each call as independent and apply full focus to the one at hand

Compartmentalizing each incident and applying full attention prevents cognitive overload across multiple high-stress calls.

Question 75: A bystander is screaming at you and demanding that you save their family member before other trapped victims. How should you handle this?

Ask another firefighter to argue with the bystander while you work
Prioritize that victim to calm the bystander
Firmly but calmly explain triage priorities and continue working systematically (Correct answer)
Stop operations until the bystander calms down

Correct answer: Firmly but calmly explain triage priorities and continue working systematically

Maintaining composure while briefly explaining triage logic manages civilian distress without compromising rescue effectiveness.

Question 76: Which sentence uses correct punctuation?

The lieutenant said: Advance the line.
The lieutenant said; 'Advance the line.'
The lieutenant said, 'Advance the line.' (Correct answer)
The lieutenant said 'Advance the line.'

Correct answer: The lieutenant said, 'Advance the line.'

A comma is the correct punctuation before a direct quotation in this context.

Question 77: If 4 firefighters can complete a search of a floor in 12 minutes, how long would the same search take with 6 firefighters (assuming equal work distribution)?

9 minutes
6 minutes
10 minutes
8 minutes (Correct answer)

Correct answer: 8 minutes

Total work = 4 × 12 = 48 person-minutes; 48 ÷ 6 = 8 minutes.

Question 78: A nozzle has a flow rate of 250 gallons per minute. A tank holds 1,500 gallons. How long, in minutes, before the tank is empty?

6 min (Correct answer)
7 min
4 min
5 min

Correct answer: 6 min

1,500 ÷ 250 = 6 minutes.

Question 79: You have strong personal opinions about a specific firefighting tactic that differs from your department's standard operating procedure. You should:

Convince your crew to adopt your method informally
Advocate for reviewing the SOP through proper channels while following it in the field (Correct answer)
Only follow the SOP when supervisors are watching
Use your preferred tactic during incidents regardless of the SOP

Correct answer: Advocate for reviewing the SOP through proper channels while following it in the field

SOPs exist for safety and consistency; proper channels allow for legitimate revision without compromising field operations.

Question 80: Which of the following is a critical factor in building long-term resilience to the cumulative stress inherent in a firefighting career?

Relying solely on the department's formal stress debriefing programs.
Avoiding discussions about difficult calls to prevent re-living them.
Focusing exclusively on work to become an expert in the field.
Having a strong personal support system and healthy coping mechanisms outside of work. (Correct answer)

Correct answer: Having a strong personal support system and healthy coping mechanisms outside of work.

Long-term resilience is heavily dependent on factors outside the immediate work environment, such as family, friends, and healthy hobbies. These elements provide an outlet and a foundation of support for processing the chronic stress of the job. While formal programs are helpful, they are not sufficient on their own.

Question 81: A firefighter pumped 12 gallons of fuel into one tank, 17 gallons into the next tank, and 21 gallons into the last tank. How many gallons of fuel did the firefighter pump?

53
50 (Correct answer)
49
47

Correct answer: 50

Explanation: To solve the question you have to add up the three amounts of fuel pumped: 12 + 17 + 21 = 50

Question 82: During a mayday transmission, what does the acronym LUNAR stand for?

Location, Unit, Name, Assignment, Resources needed (Correct answer)
Last known position, Unit, Number of victims, Air supply, Radio channel
Level, Unit, Name, Assignment, Radio channel
Location, Unit, Name, Air supply, Resources needed

Correct answer: Location, Unit, Name, Assignment, Resources needed

LUNAR (Location, Unit, Name, Assignment, Resources needed) is the standard format for a firefighter mayday call to transmit critical information quickly.

Question 83: What does IDLH stand for, and what is the significance of the concept in firefighting?

Internal Danger Level Hazard; guides evacuation distance calculations
Instantaneous Danger for Life and Health; triggers automatic suppression systems
Integrated Dose Limit for Hazardous chemicals; sets exposure time limits
Immediately Dangerous to Life or Health; defines conditions requiring SCBA use (Correct answer)

Correct answer: Immediately Dangerous to Life or Health; defines conditions requiring SCBA use

IDLH (Immediately Dangerous to Life or Health) defines atmospheres where a 30-minute exposure could cause irreversible harm or prevent escape, requiring SCBA.

Question 84: A firefighter is ordered by a supervisor to perform a task that the firefighter believes violates a safety regulation. What is the best first step?

Comply without question to respect the chain of command
Refuse the order immediately without explanation
Voice the safety concern to the supervisor before acting (Correct answer)
Perform the task and file a grievance afterward

Correct answer: Voice the safety concern to the supervisor before acting

Raising a safety concern through proper communication before acting respects the chain of command while fulfilling a duty to prevent harm.

Question 85: On three separate emergency calls, you notice that your crew partner, Firefighter Davis, complains of a headache and dizziness shortly after exiting the fire apparatus. Each time, the apparatus was running inside the station bay for several minutes before leaving. What is the most likely problem?

The stress of emergency calls is causing physical symptoms in Firefighter Davis.
The station's ventilation system may be malfunctioning, leading to carbon monoxide buildup. (Correct answer)
The fire apparatus is old and needs to be replaced immediately.
Firefighter Davis is likely allergic to the diesel exhaust.

Correct answer: The station's ventilation system may be malfunctioning, leading to carbon monoxide buildup.

This question assesses inductive reasoning, which involves combining separate pieces of information to form a general conclusion. The recurring pattern of symptoms (headache, dizziness) linked to a specific condition (apparatus running in the bay) points to a potential environmental cause. A malfunctioning ventilation system allowing for carbon monoxide accumulation is a serious hazard that would explain these symptoms in an enclosed space.

Question 86: When a firefighter raises a concern about a procedure during a post-incident debrief, a team-oriented captain should:

Redirect the discussion to recognize positive performance only
Wait for the firefighter to submit a formal written complaint
Acknowledge the concern and involve the crew in evaluating it (Correct answer)
Dismiss the concern to keep the debrief focused and efficient

Correct answer: Acknowledge the concern and involve the crew in evaluating it

Acknowledging concerns during debriefs encourages a culture of psychological safety, which improves future team performance.

Question 87: A fire extinguisher weighing 12 lbs is placed on a shelf 5 feet from the floor. A second extinguisher weighing 18 lbs is on a shelf 3 feet from the floor. What is the combined weight of both extinguishers?

25 lbs
30 lbs (Correct answer)
33 lbs
28 lbs

Correct answer: 30 lbs

12 + 18 = 30 lbs (shelf heights are irrelevant to total weight).

Question 88: Dispatch states: 'Units respond to 1840 Maple Ave for a reported gas leak; occupants are evacuating.' What is the highest priority upon arrival?

Identify the gas source
Ensure occupants are clear of the structure (Correct answer)
Notify the gas company
Set up a command post

Correct answer: Ensure occupants are clear of the structure

Life safety is the top priority; confirming occupants are clear protects lives before addressing the hazard.

Question 89: During a confined space rescue, one of your team members signals distress and cannot continue. With limited personnel, you should:

Abort the rescue to preserve all team members
Withdraw the distressed member, reassign roles immediately, and continue the rescue with remaining team (Correct answer)
Leave the distressed member in place and continue as if nothing occurred
Order the distressed member to continue until the victim is secured

Correct answer: Withdraw the distressed member, reassign roles immediately, and continue the rescue with remaining team

Withdrawing an incapacitated team member and rapidly redistributing roles maintains both crew safety and mission continuity.

Question 90: A firefighter uses a department vehicle for a personal errand while off duty without authorization. This is best described as:

Permissible as long as the firefighter refuels the vehicle
Misuse of public resources and a violation of professional conduct (Correct answer)
Acceptable if the errand is brief and harmless
A minor infraction that supervisors overlook

Correct answer: Misuse of public resources and a violation of professional conduct

Unauthorized personal use of department property constitutes misuse of public resources and violates the trust placed in public servants.

Question 91: A fire station door uses a counterbalance spring mechanism. If the spring tension is set too low, the door will:

Close too fast (Correct answer)
Fail to stay open
Become harder to open
Open too fast

Correct answer: Close too fast

Insufficient spring tension means the counterbalance cannot offset gravity, allowing the door to close faster than desired.

Question 92: A fire crew is assigned the monotonous task of testing and documenting every fire hydrant in their district. The crew's morale is visibly low. What is the MOST effective action for the company officer to take to motivate the team?

Explain how accurate hydrant data is critical for their own engine company's effectiveness and could be the deciding factor in saving a life during a fire. (Correct answer)
Cancel the task for the day and focus on more engaging training drills instead.
Turn the task into a competition to see which pair of firefighters can finish their section the fastest.
Threaten the crew with less desirable station duties if the task is not completed with enthusiasm.

Correct answer: Explain how accurate hydrant data is critical for their own engine company's effectiveness and could be the deciding factor in saving a life during a fire.

Connecting a tedious task to the department's core mission is a key motivational strategy. By explaining the 'why' behind the work, the officer gives the crew a sense of purpose and shows how their effort directly contributes to operational readiness and public safety.

Question 93: A tanker holds 2,500 gallons. A pumper uses water at 300 gallons per minute. How many minutes until the tanker is empty?

7 minutes
8.3 minutes (Correct answer)
8 minutes
9 minutes

Correct answer: 8.3 minutes

2,500 ÷ 300 ≈ 8.33 minutes.

Question 94: You are assigned to a station where interpersonal tensions between crew members are affecting teamwork. As a newer member, what is your best approach?

Avoid interacting with either group until tensions resolve
Take sides with the majority to fit in
Immediately report the situation to senior leadership
Remain neutral, model professional behavior, and encourage resolution (Correct answer)

Correct answer: Remain neutral, model professional behavior, and encourage resolution

New members contribute most by modeling professionalism and fostering resolution rather than taking sides or escalating unnecessarily.

Question 95: All Fire Department vehicles shall be regularly inspected and tested and preventive maintenance shall be conducted to ensure that vehicles are in proper operating condition. A vehicle shall be considered unsafe and placed out of service if deficiencies are detected in one or more of the following areas: Brake system, cab and/or body mounting, steering, door latches, suspension, seatbelts, wheels or tires, windshield, windshield wipers, windshield defroster, throttle, transmission or driveline. Other deficiencies may or may not require a vehicle to be placed out of service. Any safety-related deficiency, that does not require the vehicle to be taken out of service, shall be repaired as quickly as possible. Driving back to the fire department after an incident you notice the first gear of the gearbox doesn't work. However, you are still able to drive the car from the second gear. When you arrive back at the fire department, how will you mark the vehicle?

In service - repair within four weeks.
Nothing should be marked.
Not in service until repaired. (Correct answer)
In service - repair as soon as possible.

Correct answer: Not in service until repaired.

Explanation: A significant problem with the gearbox (transmission) is considered unsafe, therefore the vehicle should be marked as out of service until repaired.

Question 96: A captain gives the following written instruction: 'All probationary firefighters must meticulously inspect their SCBA (Self-Contained Breathing Apparatus) daily; any deficiencies, no matter how minor, must be documented and reported to the shift officer immediately.' What is the meaning of the word 'meticulously' in this context?

With the help of a partner
Quickly and efficiently
With extreme care and attention to detail (Correct answer)
At a regularly scheduled time

Correct answer: With extreme care and attention to detail

The word 'meticulously' means to do something with great attention to detail, precision, and care. In the context of inspecting life-saving equipment like an SCBA, this level of thoroughness is critical.

Question 97: Firefighters laid hose in three sections measuring 150 ft, 225 ft, and 175 ft. They then removed a 50-ft section for a different deployment. What is the total remaining hose length?

500 ft (Correct answer)
550 ft
475 ft
450 ft

Correct answer: 500 ft

150 + 225 + 175 = 550 ft; 550 − 50 = 500 ft.

Question 98: A firefighter is performing the weekly maintenance check on a chainsaw. Place the following steps in the most logical and safe order. 1. Check the fuel and bar oil levels, and refill if necessary. 2. Start the saw to ensure it runs properly and the chain brake functions. 3. Disengage the chain brake and inspect the chain for proper tension and sharpness. 4. Ensure the saw is off, and clean debris from the cooling fins, air filter, and chain cover.

4, 3, 1, 2 (Correct answer)
3, 1, 4, 2
2, 4, 1, 3
1, 4, 3, 2

Correct answer: 4, 3, 1, 2

Safety dictates that mechanical inspections and cleaning should be done while the tool is off. Therefore, the first step is to clean the saw (4). Next, with the saw still off, the firefighter can safely handle the chain to check its tension and condition (3). After the mechanical checks are complete, fluids can be topped off (1). The final step is to start the saw to functionally test its operation and safety features like the chain brake (2).

Question 99: Two fire engines start from the same station. Engine A travels north at 50 mph and Engine B travels south at 40 mph. After 30 minutes, how far apart are they?

40 miles
35 miles
45 miles (Correct answer)
50 miles

Correct answer: 45 miles

In 0.5 hours, A travels 25 miles and B travels 20 miles; total separation = 45 miles.

Question 100: A firefighter's protective gear weighs 45 pounds. If the gear represents 22% of the firefighter's total equipped weight, what is the total equipped weight (rounded to the nearest pound)?

215
205 (Correct answer)
195
180

Correct answer: 205

45 ÷ 0.22 ≈ 204.5, rounded to 205 pounds.

Question 101: Your station chief asks for feedback on a new policy before it is finalized. You believe it will create operational problems. You should:

Complain to colleagues instead of responding officially
Stay silent to avoid appearing critical
Agree with the policy to support leadership
Provide honest, specific, and constructive feedback (Correct answer)

Correct answer: Provide honest, specific, and constructive feedback

Solicited feedback should be honest and constructive; withholding concerns or complaining informally undermines effective policy development.

Question 102: A water tank is filled through a 2-inch pipe at 60 gallons per minute and drained through a 1-inch pipe at 30 gallons per minute. The net fill rate of the tank is:

90 gpm
60 gpm
30 gpm (Correct answer)
15 gpm

Correct answer: 30 gpm

Net fill rate = inflow minus outflow = 60 - 30 = 30 gallons per minute.

Question 103: Which breathing technique is most recommended for firefighters to quickly reduce acute stress during a high-pressure situation?

Tactical or diaphragmatic breathing with slow, controlled exhales (Correct answer)
Rapid shallow breathing to increase alertness
Holding the breath for 10 seconds to reset the nervous system
Breathing through the mouth only to maximize oxygen intake

Correct answer: Tactical or diaphragmatic breathing with slow, controlled exhales

Tactical breathing—slow, deep inhalation followed by a controlled exhale—activates the parasympathetic system and reduces the acute stress response.

Question 104: Why is it important for firefighters to maintain professional conduct even during off-duty hours?

Off-duty behavior has no real impact on their career
Their conduct reflects on the department and affects public trust (Correct answer)
Firefighters are always technically on call
The department can dock pay for off-duty behavior

Correct answer: Their conduct reflects on the department and affects public trust

Firefighters are public servants and community figures whose off-duty conduct shapes the public's perception of the entire department.

Question 105: A firefighter descending a ladder faces the building. Their left hand grips the left rail. If the firefighter rotates 180 degrees to face away from the building, the left hand now grips the:

The rungs
Right rail (Correct answer)
Left rail
Both rails

Correct answer: Right rail

Rotating 180 degrees swaps left and right orientation relative to the ladder, so the original left rail is now gripped by the right hand, and vice versa.

Question 106: Three separate calls come into the dispatch center from the same large apartment complex within five minutes. The first reports a fire alarm sounding, the second reports the smell of smoke in a hallway, and the third reports seeing smoke coming from a third-floor window. Which of the following represents the MOST accurate conclusion from this information?

The calls are likely unrelated incidents occurring simultaneously.
The alarm system is likely malfunctioning due to a power surge.
There is a high probability of a working fire that is escalating. (Correct answer)
A small cooking fire was likely extinguished, but the smoke is still lingering.

Correct answer: There is a high probability of a working fire that is escalating.

This question assesses inductive reasoning, which involves combining separate pieces of information to form a general conclusion. [1, 13] The three independent reports (alarm, smell of smoke, visible smoke) all point to the same event. Taken together, they strongly indicate a developing fire incident, rather than a malfunction or a minor, resolved issue. This pattern suggests an escalating event requiring a full emergency response.

Question 107: A memo reads: 'All equipment checks must be completed within the first 30 minutes of each shift and documented in the apparatus log.' A firefighter finishes their check at 35 minutes. They should:

Document the check and note the delay with a reason (Correct answer)
Ask a colleague to sign off as if they did the check on time
Backdate the log entry to show 30 minutes
Skip documentation since it was late anyway

Correct answer: Document the check and note the delay with a reason

Accurate recordkeeping requires honest documentation, including noting the delay and reason rather than falsifying the log.

Question 108: A significant component of any safe operation is that of a solid tactical briefing. A five-step briefing process can be used. Remember, it is just the critical information you are conveying. If practiced and used in all incidents and training, officers and firefighters should be able to touch on the five highlights in as little as 30 seconds. If more time is available, it can be used to facilitate a more thorough briefing. 1) Assignment — Make sure that everyone knows their role. 2) Current situation — Helps to update everyone's situational awareness. 3) Questions/concerns — To and from the crew, if the company officer is the only one talking, other crew members may be experiencing barriers to situational awareness. 4) How to support the assignment — This will include safety support, logistical support, and of course what you need to accomplish the task/tactic. 5) How to make the assignment safe — Will expand on the hazards present and end with how to mitigate them. What is the most logical order of the briefing?

1, 2, 4, 5, 3
2, 1, 5, 4, 3 (Correct answer)
2, 1, 3, 5, 4
1, 2, 5, 3, 4

Correct answer: 2, 1, 5, 4, 3

Explanation: This is the correct order of the briefing: 1. Current situation — Helps to update everyone's situational awareness. 2. Assignment - Make sure that it is known to everyone. Hazard identification is here. 3. How to make the assignment safe — Will expand on the hazards present and end with how to mitigate them. 4. How to support the assignment — This will include safety support, logistical support, and of course what you need to accomplish the task/tactic. 5. Questions/concerns - To and from the crew, if the company officer is the only one talking, other crew members may be experiencing barriers to situational awareness.

Question 109: Which scenario best illustrates the principle of equal treatment in the fire service?

Applying the same rules and standards consistently to all personnel (Correct answer)
Assigning the most dangerous tasks to the newest recruits
Giving senior firefighters preferential scheduling regardless of policy
Providing extra mentoring only to firefighters from certain backgrounds

Correct answer: Applying the same rules and standards consistently to all personnel

Equal treatment requires that policies, standards, and opportunities be applied consistently to all personnel regardless of personal characteristics or seniority.

Question 110: After a difficult call where your crew performed well under pressure, the best thing to do for long-term team cohesion is:

Allow voluntary informal debriefing and acknowledge the team's performance (Correct answer)
Celebrate with crew members who performed best only
Move immediately to the next assignment without dwelling on past calls
Require a formal written report from each crew member

Correct answer: Allow voluntary informal debriefing and acknowledge the team's performance

Voluntary informal debriefs combined with recognition support psychological resilience and reinforce team cohesion after high-stress incidents.

Question 111: A firefighter lifts a 45-pound hose bundle and carries it 120 feet in 30 seconds. What is the carrying speed in feet per second?

6 ft/s
4 ft/s (Correct answer)
5 ft/s
3 ft/s

Correct answer: 4 ft/s

120 ÷ 30 = 4 feet per second.

Question 112: A fire station runs 3 shifts of 24 hours each. If each shift has 8 firefighters, how many total firefighter-hours are worked in one full rotation?

448
512
624
576 (Correct answer)

Correct answer: 576

3 shifts × 24 hours × 8 firefighters = 576 firefighter-hours.

Question 113: An engine company arrives at a two-story single-family home with nothing showing from the exterior. The homeowner, who is waiting outside, states they came home to a smoke-filled kitchen after leaving a pot on the stove. They opened the windows and the smoke has mostly cleared, but they are still concerned. Which of the following observations would present the GREATEST potential problem?

Dark, heat-stained paint on the wall behind the stove. (Correct answer)
The kitchen window is shattered from the heat.
A light haze of smoke still visible near the ceiling.
The smoke alarm on the first floor is beeping intermittently.

Correct answer: Dark, heat-stained paint on the wall behind the stove.

This question requires problem sensitivity to identify the most significant potential hazard. [1] While all options indicate a problem, the dark, heat-stained paint behind the stove suggests that the fire extended from the pot into the wall structure itself. This indicates a hidden fire within the walls (an extension), which is a much more serious problem than residual smoke, a broken window, or a beeping detector. It requires immediate investigation to prevent a larger structural fire.

Question 114: Station logs show 12 structure fires, 35 vehicle fires, and 8 wildland fires last month. What fraction of all fires were structure fires?

2/9
1/5 (Correct answer)
11/55
6/27

Correct answer: 1/5

Total fires = 12 + 35 + 8 = 55; 12/55 simplifies... actually 12/55 does not simplify to 1/5 — 12/55 is the exact fraction, equal to approximately 21.8%. The closest answer is 1/5 (20%), making it the best available choice.

Question 115: Which approach is most effective when a firefighter feels overwhelmed by accumulated stress between incidents?

Request only low-risk calls until the feeling passes
Increase physical training intensity to exhaust the body before rest
Avoid discussing stress so as not to burden colleagues
Use structured recovery practices such as peer conversations, mindfulness, or professional counseling (Correct answer)

Correct answer: Use structured recovery practices such as peer conversations, mindfulness, or professional counseling

Structured recovery—whether peer support, mindfulness, or counseling—actively processes accumulated stress rather than suppressing or avoiding it.

Question 116: What is the primary purpose of a positive pressure ventilation (PPV) fan?

To push fresh air into a structure to clear smoke (Correct answer)
To increase oxygen supply to help firefighters breathe
To create a negative pressure zone around the fire
To cool the fire compartment before entry

Correct answer: To push fresh air into a structure to clear smoke

PPV fans are positioned at an entry point to push fresh air through the structure, driving smoke and hot gases out of exhaust openings.

Question 117: An engine must lay a supply line to a hydrant that is 475 feet away. The engine carries supply hose in 50-foot sections. What is the minimum number of sections the crew must deploy to reach the hydrant?

10 sections (Correct answer)
11 sections
9 sections
8 sections

Correct answer: 10 sections

To determine the number of sections, divide the total distance by the length of one section: 475 feet / 50 feet/section = 9.5 sections. Since it's impossible to deploy half a section, the crew must use 10 full sections to ensure the hose reaches the hydrant.

Question 118: A night shift turnover protocol requires: (α) review open incidents log, (β) inspect apparatus and equipment, (γ) brief incoming crew, (δ) sign apparatus check sheet. The rule: β must precede δ; α must precede γ; δ and γ can happen in either order after their prerequisites. Which is NOT a valid sequence?

α, β, δ, γ
α, β, γ, δ
γ, α, β, δ (Correct answer)
β, α, δ, γ

Correct answer: γ, α, β, δ

Starting with γ (brief incoming crew) violates the rule that α (review open incidents) must precede γ.

Question 119: 1) Use a sweeping motion and aim at the base of the fire. 2) Make sure you have installed fire alarms and that you check the battery at least once a month. 3) Be sure to watch the area for a while to ensure it doesn't reignite. 4) Always stand with an exit at your back. 5) Inspect extinguishers once a month for dents, leaks, or other signs of damage. 6) Stand several feet away from the fire, moving closer once the fire starts to diminish. 7) If possible, use a "buddy system" to have someone back you up or call for help if something goes wrong. 8) Make sure you know how to use your fire extinguisher. Which of the items on the list above would be considered part of preparing for a fire, rather than fighting it?"

2, 4, 5, 8
2, 4, 5, 7
2, 5, 4
2, 5, 8 (Correct answer)

Correct answer: 2, 5, 8

Explanation: These are the methods to prepare for a fire: - Inspect extinguishers once a month for dents, leaks, or other signs of damage. - Make sure you know how to use your fire extinguisher. - Make sure you have installed fire alarms and that you check the battery at least once a month.

Question 120: A fellow firefighter visibly panics during a rescue operation. How should you respond?

Calmly give them a clear, specific directive to refocus them (Correct answer)
Report the issue to command immediately and wait for instructions
Ignore it and continue with your own assignment
Stop your own task and take over their role entirely

Correct answer: Calmly give them a clear, specific directive to refocus them

A calm, directive response helps a panicking colleague regain focus while keeping the overall operation on track.

Question 121: A pumper truck carries 750 gallons of water. During an operation, 40% of the water is used. How many gallons of water are remaining in the tank?

400 gallons
300 gallons
350 gallons
450 gallons (Correct answer)

Correct answer: 450 gallons

First, calculate the amount of water used: 750 gallons * 0.40 = 300 gallons. Then, subtract the amount used from the total amount to find the remaining water: 750 gallons - 300 gallons = 450 gallons. Alternatively, if 40% is used, 60% remains. 750 * 0.60 = 450 gallons.

Question 122: Your engine company arrives second on scene. The first-arriving crew has already established command. Your FIRST action should be:

Begin operations in the area that seems most urgent to you
Report to the incident commander for assignment (Correct answer)
Establish a parallel command structure to improve coverage
Wait at the apparatus until you receive direct orders from your captain

Correct answer: Report to the incident commander for assignment

Integrating into the incident command structure immediately upon arrival ensures coordinated and safe operations.

Question 123: A fire burns through 3.2 acres per hour. If the fire started at 2:00 PM and covered 16 acres by the time it was reported, at what time was it reported?

6:00 PM
7:00 PM (Correct answer)
6:30 PM
7:30 PM

Correct answer: 7:00 PM

16 ÷ 3.2 = 5 hours after 2:00 PM = 7:00 PM.

Question 124: A fire station's budget is $840,000. If equipment costs account for 37.5% of the budget, how much is spent on equipment?

$315,000 (Correct answer)
$336,000
$350,000
$294,000

Correct answer: $315,000

840,000 × 0.375 = $315,000.

Question 125: Per protocol, a firefighter must complete the following steps before entering a burning structure: (A) don SCBA, (B) establish incident command, (C) conduct 360 size-up, (D) confirm water supply. The rule states steps must follow B→C→D→A order. Which sequence is correct?

A, B, C, D
D, A, B, C
C, B, D, A
B, C, D, A (Correct answer)

Correct answer: B, C, D, A

The protocol mandates establishing command first, then size-up, confirming water supply, and donning SCBA last before entry.

Question 126: Which of the following situations requires a firefighter to disclose a potential conflict of interest to a supervisor?

The firefighter dislikes a particular type of equipment
The firefighter previously attended the same school as a department recruit
The firefighter owns rental property in a building the department is inspecting (Correct answer)
The firefighter has a family member who is also a firefighter in a different city

Correct answer: The firefighter owns rental property in a building the department is inspecting

Owning property subject to an official inspection creates a direct financial conflict of interest that must be disclosed so impartiality can be ensured.

Question 127: Which tool would a firefighter most likely use to cut through a padlock shackle during forcible entry?

Halligan bar
Pike pole
Bolt cutters (Correct answer)
Flat-head axe

Correct answer: Bolt cutters

Bolt cutters are specifically designed to cut through metal shackles and chains with high mechanical advantage.

Question 128: What type of extinguisher agent is most appropriate for a Class D metal fire?

Dry chemical powder
Dry sand or specialized dry powder agent (Correct answer)
Aqueous film-forming foam (AFFF)
Carbon dioxide (CO2)

Correct answer: Dry sand or specialized dry powder agent

Class D fires involve combustible metals like magnesium or sodium, which react violently with water and CO2; only dry sand or specialized dry powder agents are safe.

Question 129: Firefighters are given a rule: when ventilating a structure, perform steps in this order only—(P) coordinate with interior crew, (Q) open roof vent, (R) open inlet below fire, (S) confirm fire location. The correct sequence is:

S, P, R, Q (Correct answer)
R, Q, P, S
Q, R, S, P
P, S, Q, R

Correct answer: S, P, R, Q

Confirm fire location first, coordinate with interior crew, open inlet to direct flow, then open roof vent last.

Question 130: A passage explains that in a mayday situation, a firefighter activates their PASS device, announces mayday three times on the radio, and states their location and air supply. If a firefighter activates their PASS but cannot reach their radio, they should:

Immediately remove their mask to call for help verbally
Keep moving to find an exit at all costs
Shut off the PASS to conserve battery and try to self-rescue silently
Remain calm, conserve air, and await rescue after the PASS alarm alerts others (Correct answer)

Correct answer: Remain calm, conserve air, and await rescue after the PASS alarm alerts others

If radio contact is impossible, activating the PASS device and conserving air while awaiting RIT rescue is the correct protocol.

Question 131: According to a departmental directive, new firefighters must be directly supervised by a senior firefighter during all interior operations for their first 12 months. A new firefighter's supervising partner becomes separated in smoke. The new firefighter should:

Announce their location on the radio and begin exiting the structure (Correct answer)
Continue searching independently since they have enough training
Stop all movement and wait until conditions improve
Crawl toward the last known position of their partner

Correct answer: Announce their location on the radio and begin exiting the structure

Without required supervision and in a disorienting environment, a new firefighter should announce their position and begin an organized exit.

Question 132: A training bulletin states: 'A charged hose line on the first floor provides the best initial attack on a residential structure fire.' You are assigned to the second floor where fire is visible. The most appropriate action is to:

Use any available dry line on the second floor immediately
Wait on the first floor until conditions improve upstairs
Request a charged line be advanced to the second floor before attacking (Correct answer)
Ventilate the roof before any hose line is advanced

Correct answer: Request a charged line be advanced to the second floor before attacking

The bulletin emphasizes a charged line for the attack; the correct action is to request the charged line be brought to the fire floor.

Question 133: What does 'laminar flow' indicate about smoke movement in a building?

All combustible gases have been consumed and the fire is decaying
Smoke is being pushed downward by suppression water streams
Smoke is moving in a smooth, layered pattern, often signaling a lower-heat fire (Correct answer)
Smoke is mixing turbulently with fresh air, indicating high heat

Correct answer: Smoke is moving in a smooth, layered pattern, often signaling a lower-heat fire

Laminar (smooth, layered) smoke movement typically indicates a cooler, lower-energy fire, while turbulent or pulsing smoke signals high heat and potential flashover conditions.

Question 134: During a live fire training exercise, one crew member repeatedly skips safety checks. You should:

Only address it if an injury actually occurs
Avoid saying anything to maintain positive team morale
Report the behavior to the training officer immediately (Correct answer)
Complete the skipped checks yourself without informing anyone

Correct answer: Report the behavior to the training officer immediately

Safety violations during training must be reported immediately to prevent dangerous habits from carrying over to real emergencies.

Question 135: You are asked by a journalist at the scene of a major incident for a statement. You have not been designated as a public information officer. You should:

Decline and direct the journalist to the designated public information officer (Correct answer)
Answer only questions that seem harmless and deflect the rest
Tell the journalist nothing is happening to protect scene security
Provide a brief, factual statement since you were directly involved

Correct answer: Decline and direct the journalist to the designated public information officer

Only designated PIOs should speak to media; unauthorized statements can compromise scene security, investigations, and department messaging.

Question 136: A new department policy states: 'All personnel must complete the annual physical fitness assessment by the end of the second quarter. No exceptions will be granted unless a formal request is submitted through the chain of command and approved by the Fire Chief.' According to this policy, how could a firefighter be excused from the assessment?

By getting a doctor's note and giving it directly to the Fire Chief.
By submitting a written request that is officially approved by the highest authority. (Correct answer)
By verbally telling their station captain they are unable to participate.
By waiting until the third quarter to see if the policy is still in effect.

Correct answer: By submitting a written request that is officially approved by the highest authority.

The policy explicitly outlines a formal process: a 'formal request' must be 'submitted through the chain of command' and ultimately 'approved by the Fire Chief.' This matches the description in the correct answer. The other options ignore parts of this required formal process.

Question 137: A water supply rule for rural fires states: (I) establish a tanker shuttle, (II) calculate flow demand, (III) identify the nearest water source, (IV) assign fill site and dump site. The rule says III must precede IV, and II must precede I. Which order satisfies both rules?

I, III, II, IV
III, II, IV, I
II, III, IV, I (Correct answer)
II, IV, III, I

Correct answer: II, III, IV, I

Calculate flow demand first, then locate the water source, assign fill/dump sites, then establish the shuttle.

Question 138: A firefighter observes another firefighter taking a small piece of personal property from a fire victim's home while clearing the scene. What should the firefighter do?

Confront the firefighter privately and let them return the item
Report the theft to a supervisor immediately (Correct answer)
Stay quiet since it was only a small item
Wait to see if the victim reports anything missing

Correct answer: Report the theft to a supervisor immediately

Theft from a victim's home is a serious crime and ethical breach that must be reported immediately to protect the victim and the department's integrity.

Question 139: A firefighter is asked by a local reporter about an ongoing arson investigation. The correct response is to:

Confirm or deny only the most basic facts
Speculate about the cause to help the reporter meet their deadline
Decline to comment and direct the reporter to the department's public information officer (Correct answer)
Share what the crew knows since transparency is important

Correct answer: Decline to comment and direct the reporter to the department's public information officer

Commenting on active investigations can compromise them; only the designated PIO should speak with media to ensure accurate and appropriate disclosures.

Question 140: A firefighter must thread a ¾-inch hose coupling. Turning the coupling counterclockwise will:

Depend on the thread type
Tighten it
Loosen it (Correct answer)
Have no effect

Correct answer: Loosen it

Standard right-hand threads loosen when turned counterclockwise, following the righty-tighty, lefty-loosey rule.

Question 141: A firefighter suspects a colleague is showing signs of substance abuse while on duty. The best course of action is to:

Handle it informally by warning the colleague
Report the concern to a supervisor to protect the crew and public (Correct answer)
Wait until the end of the shift to avoid confrontation
Ignore it unless performance visibly declines

Correct answer: Report the concern to a supervisor to protect the crew and public

Reporting suspected on-duty substance abuse is essential to crew safety and public protection, which outweigh concerns about colleague relationships.

Question 142: Choose the word that best completes the following sentence: 'The incident commander's ability to __________ clear and concise orders over the radio is essential for maintaining control of an emergency scene.'

articulate (Correct answer)
fabricate
deliberate
insinuate

Correct answer: articulate

'Articulate' means to express an idea or feeling fluently and coherently. This is the most appropriate word to describe the clear communication required from an incident commander.

Question 143: A local business owner offers a firefighter a cash gift after the crew responds to a fire at his property. How should the firefighter respond?

Accept it quietly since the work was difficult
Accept it and donate it to the department fund
Take the gift and report it to a supervisor later
Politely decline and explain that accepting gratuities is not permitted (Correct answer)

Correct answer: Politely decline and explain that accepting gratuities is not permitted

Firefighters must decline gratuities to avoid real or perceived conflicts of interest and to maintain public trust in the department.

Question 144: A ventilation decision tree states: if the fire is in a basement, ventilate horizontally before vertically. Steps: (P) open windows on opposite side of fire, (Q) open roof hatch, (R) confirm basement fire location, (S) open windows on fire side. Correct sequence for a confirmed basement fire:

R, P, S, Q (Correct answer)
R, Q, P, S
Q, R, P, S
R, S, P, Q

Correct answer: R, P, S, Q

Confirm location, open opposite-side windows first (horizontal ventilation), then fire-side windows, then roof hatch if needed.

Question 145: A firefighter is told the supply pump is 200 feet west and 150 feet north of their position. Without a map, the firefighter estimates the straight-line distance to the pump is approximately:

175 feet
200 feet
250 feet (Correct answer)
350 feet

Correct answer: 250 feet

Using the Pythagorean theorem: √(200² + 150²) = √(40,000 + 22,500) = √62,500 = 250 feet.

Question 146: If Engine 3 arrives at 14:07 and the fire is declared under control at 15:52, how long did suppression operations last?

1 hour 45 minutes (Correct answer)
1 hour 55 minutes
2 hours 5 minutes
1 hour 35 minutes

Correct answer: 1 hour 45 minutes

From 14:07 to 15:52 is 1 hour and 45 minutes.

Question 147: A senior firefighter notices that a crew member appears withdrawn and disengaged during shift. The MOST team-oriented response is:

Check in privately to show concern and assess if the member needs support (Correct answer)
Ignore it since personal matters should stay separate from work
Report it immediately to the union representative
Tell the crew member to 'snap out of it' in front of the group

Correct answer: Check in privately to show concern and assess if the member needs support

Proactively checking in on a struggling teammate reflects team care and can prevent impaired performance or safety issues.

Question 148: Select the line that contains the misspelled word, grammatical error, or punctuation error. "The incident commander is the person responsible for all aspects of an emergency response including quickly managing all incident operations and responsibility for all persons envolved."

The incident commander is the person
and responsibility for all persons envolved. (Correct answer)
responsible for all aspects of an emergency response,
including quickly managing all incident operations

Correct answer: and responsibility for all persons envolved.

Explanation: The correct answer is D. Envolved is misspelled, it should say "involved."

Question 149: A fire truck has a 500-gallon water tank. After fighting a fire, 340 gallons remain. What percentage of water was used?

66%
32% (Correct answer)
34%
68%

Correct answer: 32%

Used = 500 − 340 = 160; 160 ÷ 500 = 0.32 = 32%.

Question 150: A firefighter is asked by a neighbor to share details about a recent house fire in the neighborhood. The best response is to:

Share details since it will build goodwill in the community
Share all details since the neighbor is a community member
Refuse to speak entirely to avoid any risk
Provide only publicly available information and direct them to the department's public information officer (Correct answer)

Correct answer: Provide only publicly available information and direct them to the department's public information officer

Referring public inquiries to the PIO and sharing only authorized information protects privacy and ensures consistent, accurate public communication.

Question 151: Firefighters arrive at a fire in an office building. The building is a one-story building with 8 small offices. The manager of the office building was the only one standing outside the office when the firefighters arrived. He gave the firefighters the following information: Manager: ""I arrived just before you did, so I haven't been in the building yet. You need a keycard to access the building so I am certain that the only people who could be inside at the time are my 8 employees; they occupy one office each. I let my employees govern their own schedule, so I cannot say if some of them are out of the office building on meetings or have decided to come in late today."" As the firefighters approach the building, they see people gathered outside, it is some of the employees of the building. From the employees, they get the following information: Christina: ""I was in Michael's office when the alarm sounded; we left the building together."" Frank: ""I left the building as fast as I could. I know that Lance is home sick today and Brian is in a meeting downtown."" Linda: ""I ran out immediately when I heard the fire alarm. I ran past Lisa's office on my way out, but I did not see her in her office."" Victor: ""I was out getting my lunch. When I came back I saw the smoke and my colleagues running out of the building."" Will the firefighters enter the building to look for people still inside?

No, the risk is too high to enter.
Yes, a person is still inside.
No, no one is inside.
Yes, a person could still be inside. (Correct answer)

Correct answer: Yes, a person could still be inside.

Explanation: There are 8 offices in the building with 8 employees. We know the following: Christina: Evacuated Michael: Evacuated Frank: Evacuated Lance: Home sick Brian: Meeting downtown Linda: Evacuated Victor: Not inside Lisa: She may be in her office, we cannot be certain, but she could still be inside.

Question 152: A firefighter who frequently deflects blame onto teammates after mistakes is MOST damaging to the team because:

It creates more paperwork for supervisors to process
It wastes time that could be spent on training
It erodes trust and reduces the team's willingness to take initiative (Correct answer)
It motivates other team members to perform better to compensate

Correct answer: It erodes trust and reduces the team's willingness to take initiative

Blame-shifting destroys psychological safety, causing teammates to become defensive and less willing to take the risks needed for proactive performance.

Question 153: A policy reads: 'All hazardous materials incidents require a minimum safety zone of 300 feet for unknown substances until identification is made.' A responder believes the substance is a common cleaning agent and sets up 100 feet away. This is:

Acceptable if the responder has hazmat training
Appropriate because cleaning agents are low risk
A policy violation — 300 feet is required until the substance is identified (Correct answer)
Correct only if a supervisor approves the reduced distance

Correct answer: A policy violation — 300 feet is required until the substance is identified

Until a substance is formally identified, the policy requires 300 feet regardless of the responder's assumption about the material.

Question 154: A pump operator needs to supply water to a nozzle at the top of a 5-story building. The required nozzle pressure is 100 psi. There is a pressure loss of 25 psi due to friction in the hose. Additionally, the department calculates a pressure loss of 5 psi for each story of elevation. What is the required pump discharge pressure (PDP)?

150 psi (Correct answer)
175 psi
130 psi
125 psi

Correct answer: 150 psi

The total pump discharge pressure (PDP) is the sum of all pressures that must be overcome. This includes Nozzle Pressure (100 psi), Friction Loss (25 psi), and Elevation Loss (5 stories * 5 psi/story = 25 psi). Therefore, the calculation is: 100 + 25 + 25 = 150 psi.
