Exams | Verified Answers &
Rationale | A+ Graded
Version A
1. What is the primary objective of a Firefighter II during a structural fire response?
A. Property conservation
B. Life safety
C. Incident documentation
D. Equipment maintenance
Answer: B
Rationale: Life safety is the top priority for Firefighter II operations, ensuring the
protection of occupants and firefighters, as outlined in NFPA 1001.
2. Which NFPA standard defines the requirements for Firefighter II training?
A. NFPA 1500
B. NFPA 1001
C. NFPA 1582
D. NFPA 1901
Answer: B
Rationale: NFPA 1001, Standard for Fire Fighter Professional Qualifications, specifies
the skills and knowledge required for Firefighter II, including advanced fire suppression
and rescue techniques.
3. What is the most effective extinguishing agent for a Class K fire?
A. Water
B. Dry chemical
C. Wet chemical
D. Carbon dioxide
Answer: C
Rationale: Wet chemical agents are designed for Class K fires involving cooking oils,
forming a saponification layer to suppress the fire and prevent reignition, per NFPA 10.
4. What is the first action a Firefighter II should take before entering a smoke-filled
building?
A. Deploy a hose line
B. Ventilate the structure
C. Don SCBA and verify air supply
, 2
D. Conduct a 360-degree size-up
Answer: C
Rationale: Donning SCBA and verifying the air supply ensures firefighter safety against
toxic smoke inhalation, a critical step before entering a hazardous environment, per
NFPA 1001.
5. Which ventilation method is most effective for a fire in a single-story commercial
building?
A. Negative pressure ventilation
B. Vertical ventilation
C. Positive pressure ventilation
D. Hydraulic ventilation
Answer: C
Rationale: Positive pressure ventilation (PPV) efficiently clears smoke and heat by
forcing air into the structure, improving visibility and safety, per NFPA 1001.
6. What is the primary indicator of a potential flashover in a compartment fire?
A. Decreasing smoke density
B. Intense heat and rollover flames
C. Clear visibility
D. Reduced fire spread
Answer: B
Rationale: Intense heat and rollover flames across the ceiling indicate a buildup of
unburned gases, signaling an impending flashover, per NFPA 1001.
7. When inspecting a fire hydrant, what is the first priority?
A. Check water flow
B. Ensure accessibility
C. Test valve operation
D. Inspect nozzle threads
Answer: B
Rationale: Ensuring the hydrant is accessible (free of obstructions) is the first priority to
guarantee it can be used in an emergency, per NFPA 1001.
8. Which knot is most suitable for securing a tool during a hoist?
A. Figure-eight
B. Clove hitch
C. Bowline
D. Square knot
Answer: C
Rationale: The bowline is a strong, reliable knot that does not slip under load, making it
ideal for hoisting tools, per NFPA 1001.
9. What is a Firefighter II’s primary responsibility within the incident command
system (ICS)?
A. Develop incident objectives
B. Perform assigned operational tasks
C. Coordinate resource logistics
D. Serve as incident commander
Answer: B
, 3
Rationale: Firefighter II personnel execute advanced tasks, such as fire suppression or
rescue, under supervision within the ICS, per NFPA 1001.
10. Which extinguishing agent is most appropriate for a Class D fire involving sodium?
A. Water
B. Dry powder
C. Foam
D. Carbon dioxide
Answer: B
Rationale: Dry powder agents designed for Class D fires smother combustible metal
fires like sodium without reacting, unlike water, which can cause explosions, per NFPA
10.
11. What should a Firefighter II do if their SCBA low-air alarm sounds during an
operation?
A. Continue until air is fully depleted
B. Immediately exit to a safe area
C. Request a new SCBA unit
D. Switch to buddy breathing
Answer: B
Rationale: A low-air alarm indicates limited remaining air, requiring immediate exit to a
safe area to avoid respiratory hazards, per NFPA 1001.
12. What is the purpose of a fire department connection (FDC) on a building?
A. Vent smoke from the structure
B. Supply water to sprinklers or standpipes
C. Connect to the municipal water main
D. Provide cooling for HVAC systems
Answer: B
Rationale: The FDC allows firefighters to supply water to a building’s sprinkler or
standpipe system, enhancing fire suppression, per NFPA 14.
13. Which factor most significantly impacts fire behavior in a structure?
A. Building construction
B. Ventilation
C. Fuel load
D. Ambient humidity
Answer: B
Rationale: Ventilation controls oxygen availability, directly influencing fire intensity and
spread, making it a critical factor, per NFPA 1001.
14. What is the safest tool for breaching a reinforced steel door during forcible entry?
A. Axe
B. Halligan bar
C. Power saw
D. Sledgehammer
Answer: C
Rationale: A power saw with a metal-cutting blade is the safest and most effective tool
for cutting through a reinforced steel door, per NFPA 1001.
15. What is the correct sequence for closing a fire hydrant after use?
A. Open bleeder, close valve, remove hose
