A. Wind direction
B. Fuel load and oxygen availability
C. Building color
D. Electrical wiring type only
,Correct Answer: B. Fuel load and oxygen availability
Rationale: Fire growth depends primarily on available fuel and oxygen.
4. Which device is used to detect smoke in early fire detection systems?
A. Sprinkler head
B. Smoke detector
C. Fire hose
D. Hydrant valve
Correct Answer: B. Smoke detector
Rationale: Smoke detectors identify combustion particles early to trigger alarms.
5. What does PPE stand for in firefighting operations?
A. Public Protection Equipment
B. Personal Protective Equipment
C. Primary Prevention Element
D. Portable Pressure Equipment
Correct Answer: B. Personal Protective Equipment

Rationale: Hydrants supply water for firefighting operations.
11. What type of hazard is carbon monoxide?
A. Biological
B. Chemical
C. Radiological
D. Mechanical
, Correct Answer: B. Chemical
Rationale: Carbon monoxide is a toxic gas produced during combustion.
12. Which building material is most fire-resistant?
A. Wood
B. Plastic
C. Steel
D. Fabric
Correct Answer: C. Steel
Rationale: Steel has high fire resistance compared to combustible materials.
13. What is the purpose of ventilation in firefighting?
A. Increase fire intensity
B. Remove heat and smoke
C. Block oxygen flow
D. Contain fire only
Correct Answer: B. Remove heat and smoke
Rationale: Ventilation improves visibility and reduces heat buildup.
