Answers From Actual Past Papers
1. A portable fire extinguisher is selected primarily according to which combination of
factors?
A. Building height and occupancy only
B. Fire hazard, fuel type, and extinguisher rating
C. Manufacturer and cylinder color only
D. Room temperature and ceiling height only
Answer: B. Fire hazard, fuel type, and extinguisher rating
The extinguisher must be appropriate for the class of fire and the hazard being protected.
2. Which fire class involves ordinary combustible materials such as wood, paper, cloth, and
many plastics?
A. Class A
B. Class B
C. Class C
D. Class D
Answer: A. Class A
Class A fires involve ordinary combustible materials.
3. Which fire class involves flammable liquids such as gasoline, oil, and solvents?
A. Class A
B. Class B
C. Class C
D. Class K
Answer: B. Class B
Class B fires involve flammable and combustible liquids and related materials.
4. A Class C fire is primarily distinguished by the presence of:
,A. Cooking oils
B. Combustible metals
C. Energized electrical equipment
D. Ordinary combustibles
Answer: C. Energized electrical equipment
Class C identifies fires involving energized electrical equipment. Once electrical power is
removed, the remaining fuel determines the appropriate fire class.
5. Which extinguisher agent is generally unsuitable for use on energized electrical
equipment because of its electrical conductivity?
A. Carbon dioxide
B. Dry chemical
C. Water
D. Clean agent
Answer: C. Water
Water can conduct electricity and create a shock hazard when applied to energized electrical
equipment.
6. Before servicing a portable fire extinguisher, a technician should first:
A. Remove the safety pin
B. Verify the extinguisher's condition and identify the required service procedure
C. Discharge it immediately
D. Remove the cylinder valve
Answer: B. Verify the extinguisher's condition and identify the required service procedure
The technician should evaluate the extinguisher before beginning work and follow the applicable
servicing procedure.
7. What is the primary purpose of the safety pin on a portable fire extinguisher?
A. To maintain cylinder pressure
B. To prevent accidental operation
C. To prevent corrosion
D. To identify the manufacturer
Answer: B. To prevent accidental operation
The safety pin helps prevent unintended activation of the extinguisher.
, 8. The tamper seal on an extinguisher primarily indicates whether:
A. The cylinder is full
B. The extinguisher has been painted
C. The operating mechanism may have been disturbed
D. The extinguisher has passed a hydrostatic test
Answer: C. The operating mechanism may have been disturbed
The seal provides evidence that the safety pin or operating mechanism may have been accessed
or manipulated.
9. During a visual inspection, which condition requires particular attention because it can
compromise extinguisher integrity?
A. Correct labeling
B. Minor dust on the handle
C. Corrosion or physical damage
D. A readable serial number
Answer: C. Corrosion or physical damage
Corrosion, dents, leakage, or other significant physical damage can affect safe operation and
cylinder integrity.
10. A pressure gauge on a stored-pressure extinguisher is primarily used to indicate:
A. Agent type
B. Cylinder age
C. Approximate internal pressure condition
D. Hydrostatic-test date
Answer: C. Approximate internal pressure condition
The gauge provides an indication of pressure status and must be interpreted according to the
extinguisher's design and operating range.
11. If an extinguisher's pressure indicator is outside the manufacturer's normal operating
range, the technician should:
A. Ignore it if the cylinder looks clean
B. Paint the gauge
C. Evaluate and service the extinguisher according to the applicable requirements
D. Increase the pressure without inspection
Answer: C. Evaluate and service the extinguisher according to the applicable requirements
