FireTEAM Test FireTEAM Reading Comprehension Aptitude 3 — Questions and Answers
Question 1: Read the passage: 'Incident command systems (ICS) are standardized management structures used to coordinate emergency response. The incident commander holds ultimate authority and responsibility, while operations, planning, logistics, and finance sections support the response. Span of control is typically limited to 3–7 subordinates per supervisor.' What is the recommended span of control per supervisor under ICS?
- 1–3 subordinates
- 3–7 subordinates (Correct answer)
- 5–10 subordinates
- 10–15 subordinates
Correct answer: 3–7 subordinates
The passage states that span of control is typically limited to 3–7 subordinates per supervisor under ICS.
Question 2: Read the passage: 'Positive pressure ventilation (PPV) uses a high-powered fan placed at the entry point of a structure to push fresh air in and force smoke and heat out through an exit opening. For PPV to be effective, the exit opening must be approximately 1.5 times the size of the entry opening.' What size must the exit opening be relative to the entry opening for effective PPV?
- Equal in size to the entry opening
- Half the size of the entry opening
- Approximately 1.5 times the size of the entry opening (Correct answer)
- Twice the size of the entry opening
Correct answer: Approximately 1.5 times the size of the entry opening
The passage specifies that the exit opening must be approximately 1.5 times the size of the entry opening for PPV to work effectively.
Question 3: Read the passage: 'Self-contained breathing apparatus (SCBA) provides firefighters with a breathable air supply in environments that are immediately dangerous to life or health (IDLH). A standard SCBA cylinder holds approximately 45 minutes of air under normal conditions, but heavy exertion can reduce this to as little as 15 minutes.' What effect does heavy exertion have on SCBA air supply?
- It extends air supply by increasing efficiency
- It has no effect on air consumption rate
- It can reduce air supply duration to as little as 15 minutes (Correct answer)
- It doubles the consumption rate but never below 30 minutes
Correct answer: It can reduce air supply duration to as little as 15 minutes
The passage states that heavy exertion can reduce the air supply to as little as 15 minutes from the standard 45 minutes.
Question 4: Read the passage: 'A fire stream is a flow of water or foam directed at a fire. Straight streams penetrate deeply and have long reach but can disturb thermal layering. Fog patterns cover wide areas and absorb heat quickly but are less effective at long distances. Incident commanders select stream types based on fire conditions.' According to the passage, what is a disadvantage of straight streams?
- They absorb heat less efficiently than fog patterns
- They have limited reach at long distances
- They can disturb thermal layering inside the structure (Correct answer)
- They are ineffective against Class A fires
Correct answer: They can disturb thermal layering inside the structure
The passage states that straight streams can disturb thermal layering, which is listed as a disadvantage.
Question 5: Read the passage: 'Ladder safety requires that ground ladders be placed at a 75-degree angle to the structure for optimal stability. At this angle, the base of the ladder should be positioned one foot away from the structure for every four feet of working height.' If a ladder's working height is 20 feet, how far should the base be from the structure?
- 2 feet
- 4 feet
- 5 feet (Correct answer)
- 10 feet
Correct answer: 5 feet
The passage states one foot of base distance per four feet of height, so 20 feet ÷ 4 = 5 feet.
Question 6: Read the passage: 'Search and rescue operations are classified as primary or secondary. Primary search is a rapid, systematic sweep of all areas where victims are most likely to be found. Secondary search is a slower, more thorough examination of the entire structure conducted after the fire is controlled.' What distinguishes a secondary search from a primary search?
- Secondary search is faster and covers fewer areas
- Secondary search focuses only on areas with active fire
- Secondary search is slower and more thorough, done after fire control (Correct answer)
- Secondary search uses thermal imaging while primary does not
Correct answer: Secondary search is slower and more thorough, done after fire control
The passage defines secondary search as slower and more thorough, conducted after the fire is controlled.
Question 7: Read the passage: 'Water hammer is a pressure surge that occurs when a valve is closed too quickly, causing a shockwave through the hose and plumbing system. This phenomenon can damage hose couplings, burst pipes, and injure firefighters. Valves should always be opened and closed slowly to prevent water hammer.' According to the passage, what can water hammer cause?
- Increased water flow pressure for better fire suppression
- Damage to couplings, burst pipes, and potential injuries (Correct answer)
- Reduced water pressure requiring pump adjustments
- Automatic valve shutoff as a safety mechanism
Correct answer: Damage to couplings, burst pipes, and potential injuries
The passage lists damaged hose couplings, burst pipes, and firefighter injuries as consequences of water hammer.
