B. Reducing operating expenses
C. Preventing conditions that could lead to fire or explosion
D. Increasing production efficiency
Correct Answer: C. Preventing conditions that could lead to fire or explosion
Rationale: Hazardous fire prevention focuses on identifying and controlling fire risks before an
incident occurs. The other options may be business goals but are not the primary purpose of fire
prevention programs.
2. A supervisor notices several containers of flammable liquid stored without labels. What

B. Identify and properly label the containers according to applicable requirements
C. Move them outside the building
D. Ignore them if employees know their contents
Correct Answer: B. Identify and properly label the containers according to applicable
requirements
Rationale: Proper labeling is critical for hazard communication, emergency response, and safe
handling. Unlabeled containers create significant safety risks.
3. Which factor is required for combustion to occur?
A. Oxygen
B. Concrete flooring
C. Ventilation fans
D. Security monitoring
,Correct Answer: A. Oxygen
Rationale: Oxygen is one component of the fire triangle along with heat and fuel. Without
oxygen, combustion cannot be sustained.
4. During an inspection, an employee blocks access to a fire extinguisher with storage boxes.
What is the most appropriate corrective action?
A. Mark the boxes with warning labels
B. Relocate the extinguisher
C. Leave the boxes if access is possible from one side
D. Remove the obstruction and maintain clear access
Correct Answer: D. Remove the obstruction and maintain clear access

5. Which type of fire involves ordinary combustible materials such as paper and wood?
A. Class A
B. Class B
C. Class C
D. Class D
Correct Answer: A. Class A
Rationale: Class A fires involve ordinary combustibles. Class B involves flammable liquids, Class C
energized electrical equipment, and Class D combustible metals.
6. Why are routine fire safety inspections important?
A. They eliminate all fire risks permanently
B. They reduce insurance paperwork only
C. They help identify hazards before incidents occur
D. They replace employee training requirements
Correct Answer: C. They help identify hazards before incidents occur
Rationale: Inspections help detect unsafe conditions early, allowing corrective action before a

7. A storage room contains flammable liquids and ignition sources. Which action best reduces
risk?
, A. Increase storage quantities
B. Separate ignition sources from flammable materials
C. Lock the room and take no other action
D. Store liquids in open containers
Correct Answer: B. Separate ignition sources from flammable materials
Rationale: Preventing contact between fuel and ignition sources is a fundamental fire prevention
strategy.
8. What is the purpose of a fire safety plan?
A. To document payroll procedures
B. To schedule building maintenance
C. To outline actions for preventing and responding to fire emergencies
D. To replace emergency drills
Correct Answer: C. To outline actions for preventing and responding to fire emergencies
Rationale: A fire safety plan provides guidance for prevention, evacuation, emergency response,
and employee responsibilities.
9. Which practice is considered unsafe when handling flammable liquids?
A. Using approved containers
B. Maintaining ventilation
C. Keeping containers closed when not in use
D. Transferring liquids near open flames
Correct Answer: D. Transferring liquids near open flames
Rationale: Open flames can ignite flammable vapors, creating a serious fire or explosion hazard.
10. What is the best description of an ignition source?
A. Any material that can burn
B. Any condition capable of initiating combustion
C. A fire extinguisher component
D. A smoke detection device
Correct Answer: B. Any condition capable of initiating combustion
Rationale: Ignition sources include sparks, flames, hot surfaces, and electrical faults that can
start a fire.
