FCTC FCTC Reading Comprehension and Recall Questions and Answers 4 — Questions and Answers
Question 1: A training passage states: 'Backdraft results when oxygen is introduced into a superheated, oxygen-depleted environment. Warning signs include smoke pushing in and out of openings and discolored smoke.' What condition triggers a backdraft?
- Introduction of additional fuel into a burning structure
- Introduction of oxygen into a superheated oxygen-depleted space (Correct answer)
- A sudden drop in ambient temperature inside the structure
- Activation of the building sprinkler system
Correct answer: Introduction of oxygen into a superheated oxygen-depleted space
Backdraft is triggered when oxygen enters a superheated, oxygen-deficient compartment.
Question 2: A procedure reads: 'Before entering a confined space, atmospheric testing must verify oxygen levels between 19.5% and 23.5%, the absence of flammable gases, and safe toxic contaminant levels.' What oxygen level range is considered safe for entry?
- 15.0% to 18.5%
- 19.5% to 23.5% (Correct answer)
- 23.6% to 25.0%
- Any level above 16%
Correct answer: 19.5% to 23.5%
The procedure specifies that safe oxygen levels for confined space entry range from 19.5% to 23.5%.
Question 3: A guideline states: 'The two-in, two-out rule requires that when two firefighters operate in a hazardous atmosphere, two firefighters must remain outside in standby, ready to perform rescue.' What is the minimum crew needed to comply with this rule?
- One firefighter inside, one outside
- Two firefighters inside, two outside (Correct answer)
- Three firefighters inside, one outside
- Two firefighters total on scene
Correct answer: Two firefighters inside, two outside
Two-in, two-out requires two firefighters inside and two firefighters in standby outside.
Question 4: A document reads: 'Hoseline selection depends on fire conditions. A 1¾-inch line flows approximately 150–200 GPM and is suitable for most residential fires, while 2½-inch lines are used for defensive or high-volume applications.' For a defensive operation requiring high flow, which hoseline is appropriate?
- 1¾-inch line
- 1-inch booster line
- 2½-inch line (Correct answer)
- Either line performs equally
Correct answer: 2½-inch line
The document specifically states that 2½-inch lines are used for defensive or high-volume applications.
Question 5: A passage reads: 'Search and rescue priorities follow a life-safety model: rescuers target the most severely threatened, most accessible victims first. Interior search may be conducted simultaneously with fire attack when staffing permits.' What guides search priority order?
- Alphabetical order of victim names reported by dispatch
- Most severely threatened and most accessible victims first (Correct answer)
- Oldest victims are always rescued first
- Victims furthest from the fire are targeted first
Correct answer: Most severely threatened and most accessible victims first
The passage specifies that the life-safety model prioritizes the most severely threatened and most accessible victims.
Question 6: An SOP states: 'Firefighters must report any equipment defects immediately to their supervisor. Defective equipment must be tagged out of service and must not be returned to service until inspected and cleared by qualified personnel.' When can tagged-out equipment be returned to service?
- After 24 hours have passed
- After the crew chief approves verbally
- Only after inspection and clearance by qualified personnel (Correct answer)
- After the defect is reported to the next shift
Correct answer: Only after inspection and clearance by qualified personnel
The SOP requires inspection and clearance by qualified personnel before tagged-out equipment can return to service.
Question 7: A passage about fire behavior states: 'Class K fires involve cooking oils and fats at extremely high temperatures. They require wet chemical agents because water application can cause explosive steam conversion and fire spread.' Why is water not recommended for Class K fires?
- Water evaporates too quickly to be effective
- Water can cause explosive steam conversion and spread the fire (Correct answer)
- Water is not hot enough to cool cooking oils
- Water reacts chemically with cooking fat to produce toxic gas
Correct answer: Water can cause explosive steam conversion and spread the fire
The passage warns that water on Class K fires can cause explosive steam conversion and fire spread.
