Section 1: Fire Behavior and Science (Questions 1–25)
Q1. What is the primary component of the fire triangle?
A) Heat, fuel, oxygen
B) Fuel, water, heat
C) Oxygen, nitrogen, heat
D) Heat, fuel, carbon dioxide
,Correct Answer: A ✅
Rationale: The fire triangle consists of heat, fuel, and oxygen. Removing any one
extinguishes the fire.
Q2. Which stage of fire is characterized by the highest heat release rate?
A) Incipient
B) Growth
C) Fully developed
D) Decay
Correct Answer: C ✅
Rationale: The fully developed stage has the highest heat release rate and involves all
fuels burning.
Q3. What is the flash point of a liquid?
A) The temperature at which it boils
B) The lowest temperature at which it gives off vapors that ignite
C) The temperature at which it freezes
D) The temperature at which it becomes solid
Correct Answer: B ✅
Rationale: Flash point is the lowest temperature at which a liquid produces sufficient
vapor to ignite.
Q4. Which type of fire extinguisher is used for Class C fires?
A) Water
B) Foam
C) Carbon dioxide
D) Dry powder
Correct Answer: C ✅
Rationale: Class C fires involve energized electrical equipment; CO2 is non-conductive.
,Q5. What is the primary byproduct of complete combustion?
A) Carbon monoxide
B) Carbon dioxide
C) Water vapor
D) Both B and C
Correct Answer: D ✅
Rationale: Complete combustion produces carbon dioxide and water vapor.
Q6. Which NFPA standard covers fire behavior?
A) NFPA 1001
B) NFPA 921
C) NFPA 1971
D) NFPA 10
Correct Answer: B ✅
Rationale: NFPA 921 is the Guide for Fire and Explosion Investigations, covering fire
behavior.
Q7. What is a backdraft?
A) A sudden explosion of fire gases when oxygen is introduced
B) A fire that spreads rapidly uphill
C) A fire that burns underground
D) A fire that produces no smoke
Correct Answer: A ✅
Rationale: Backdraft occurs when oxygen enters a superheated, oxygen-depleted
compartment.
Q8. What is the ignition temperature of wood?
A) 100°F
B) 200°F
, C) 500°F
D) 1000°F
Correct Answer: C ✅
Rationale: Wood typically ignites around 500°F (260°C).
Q9. Which class of fire involves flammable liquids?
A) Class A
B) Class B
C) Class C
D) Class D
Correct Answer: B ✅
Rationale: Class B fires involve flammable liquids and gases.
Q10. What is the role of a thermal imaging camera (TIC)?
A) To measure water pressure
B) To detect heat signatures
C) To measure oxygen levels
D) To detect gas leaks
Correct Answer: B ✅
Rationale: TICs detect infrared radiation to visualize temperature differences.
Q11. Which NFPA standard covers firefighter protective clothing?
A) NFPA 1971
B) NFPA 1001
C) NFPA 10
D) NFPA 921
Correct Answer: A ✅
Rationale: NFPA 1971 sets standards for structural firefighting protective clothing.
