1. Which of the following is the primary responsibility of a firefighter
during the initial size-up of a fire incident?
A. Extinguishing the fire immediately
B. Assessing the situation for life safety, property conservation, and
incident stabilization
C. Coordinating media communications
D. Preparing post-incident reports
Rationale: The initial size-up is a critical step in firefighting that involves
assessing the scene to identify hazards, life safety issues, and the extent of
property damage in order to determine the appropriate strategy and
tactics.
2. What is the most effective method for preventing firefighter injuries
related to SCBA use?
A. Wearing regular work gloves
B. Proper training, regular maintenance, and adherence to usage
protocols
C. Using double masks
D. Limiting the duration of use to 10 minutes
,Rationale: Safety in SCBA (Self-Contained Breathing Apparatus) use is
ensured by rigorous training, following proper operational procedures, and
maintaining the equipment to prevent malfunctions that can cause injury.
3. During a structural fire, which factor is the most significant indicator of
potential flashover?
A. Sound of the fire alarms
B. Rapid temperature increase and smoke accumulation near the
ceiling
C. Color of the firefighter turnout gear
D. Arrival of additional units
Rationale: Flashover occurs when all combustible materials in a room
reach ignition temperature almost simultaneously, often indicated by a
sudden rise in temperature and thickening smoke near the ceiling.
4. What is the primary purpose of ventilation during a fire incident?
A. Reducing the need for water
B. Removing heat, smoke, and toxic gases to improve visibility and
conditions for firefighters and victims
C. Allowing fire trucks closer access
D. Creating a decorative smoke effect
Rationale: Ventilation controls the flow of heat and smoke, improving
conditions for both victims and firefighters, and can reduce the potential
for flashover or backdraft.
5. Which type of fire extinguisher is appropriate for a Class B fire
involving flammable liquids?
A. Water
B. Foam, CO₂, or dry chemical extinguishers
C. Wet chemical
D. Sand
,Rationale: Class B fires involve flammable liquids; foam, CO₂, and dry
chemical extinguishers effectively interrupt the chemical reaction or
remove oxygen to extinguish the fire.
6. When performing a search and rescue in a smoke-filled environment,
the recommended search pattern is:
A. Random wandering
B. Systematic, such as right- or left-hand search, maintaining contact
with walls
C. Following the smoke direction
D. Only searching near windows
Rationale: A systematic search pattern ensures all areas are covered
efficiently while minimizing the risk of disorientation in low-visibility
conditions.
7. Which is the correct method for lifting a patient with a suspected
spinal injury?
A. Dragging by the arms
B. Using a spine board with a team lift, maintaining spinal alignment
C. Pulling from one side while lifting
D. Carrying on a single firefighter’s shoulder
Rationale: Proper spinal injury protocols require maintaining neutral
alignment using a spine board and team lift to prevent further injury.
8. What is the primary hazard associated with electrical fires?
A. Smoke inhalation only
B. Electrocution and secondary fires from energized equipment
C. Water contamination
D. Toxic foam reactions
, Rationale: Electrical fires pose the risk of electric shock, and using
inappropriate extinguishing methods can worsen the hazard. Insulating
equipment and de-energizing circuits are critical safety measures.
9. During overhaul operations after extinguishment, firefighters must:
A. Immediately leave the scene
B. Check for hidden fires and hotspots to prevent rekindling
C. Remove all building contents
D. Spray water on all surfaces regardless of fire presence
Rationale: Overhaul involves inspecting and cooling residual hot spots to
ensure the fire is completely extinguished, preventing rekindling and
further damage.
10. The “two-in, two-out” rule requires:
A. Two firefighters always rest while two fight fire
B. Two firefighters enter the hazardous area while two remain
outside for safety standby
C. Two fire trucks for every entry team
D. Two types of extinguishers per team
Rationale: This safety standard ensures immediate backup and rescue
capability for firefighters operating in hazardous atmospheres.
11. Which type of hose nozzle provides a straight stream of water
for maximum reach and penetration?
A. Fog nozzle
B. Smooth bore nozzle
C. Broken stream
D. Spray nozzle
Rationale: A smooth bore nozzle produces a concentrated, high-velocity
stream that maintains reach and penetration power, ideal for interior
attacks on fires.
