1. A fire rescue technician arriving at a structural fire with reports of
occupants trapped must first perform which critical action to ensure
both victim survival and crew safety while adhering to standard
operating procedures?
A. Immediately enter the structure through the nearest opening without
assessment
B. Conduct a size-up evaluating fire conditions, structural integrity, and
rescue priorities
C. Wait for command authorization regardless of visible life hazards
D. Deploy a hose line before assessing the situation
,Answer: B
Rationale: A thorough size-up allows the technician to evaluate hazards,
identify victims, and determine safe and effective rescue strategies while
minimizing risk to rescuers.
2. During confined space rescue operations, which atmospheric
condition poses the most immediate threat to rescuers and victims?
A. Elevated humidity levels
B. Reduced oxygen concentration below 19.5%
C. Slightly increased carbon dioxide levels
D. Presence of dust particles
Answer: B
Rationale: Oxygen levels below 19.5% are considered hazardous and can
lead to hypoxia, unconsciousness, and death, making atmospheric
monitoring essential.
3. When stabilizing a vehicle involved in a rollover collision, what is the
primary purpose of cribbing?
A. To improve vehicle aesthetics
B. To reduce noise levels during rescue
C. To prevent vehicle movement and ensure rescuer safety
D. To provide ventilation to trapped victims
,Answer: C
Rationale: Cribbing stabilizes the vehicle, preventing unintended
movement that could injure rescuers or victims during extrication.
4. In rope rescue systems, what is the function of a belay line?
A. To anchor the main rope
B. To provide a backup safety line in case the primary system fails
C. To increase rope elasticity
D. To measure rope tension
Answer: B
Rationale: A belay line acts as a secondary safety system, ensuring
protection if the primary rope or system fails.
5. Which phase of fire development is characterized by rapid
temperature increase and potential flashover conditions?
A. Incipient stage
B. Growth stage
C. Fully developed stage
D. Decay stage
Answer: B
Rationale: The growth stage involves increasing heat and flame spread,
creating conditions where flashover is likely.
, 6. What is the primary hazard associated with backdraft conditions?
A. Sudden release of water vapor
B. Explosion caused by rapid oxygen introduction into a superheated
environment
C. Collapse of structural beams
D. Electrical short circuits
Answer: B
Rationale: Backdraft occurs when oxygen is introduced into a confined,
oxygen-depleted fire, causing explosive combustion.
7. In technical rescue, what does the term “load” refer to?
A. The weight of equipment only
B. The combined weight supported by the rescue system
C. The speed of rope deployment
D. The length of rope used
Answer: B
Rationale: Load refers to the total weight, including victims and
equipment, supported by the rescue system.
8. Which tool is most appropriate for cutting through laminated
windshield glass during vehicle extrication?
