1. A stored-pressure dry chemical extinguisher has a pressure gauge that reads within the
operable range, but the cylinder is found to be empty when weighed. What should the
technician conclude?
A. The gauge is sufficient evidence that the extinguisher is fully charged
B. The extinguisher should remain in service until the next annual maintenance
C. The extinguisher is defective and should be removed from service
D. The extinguisher only requires a new tamper seal
Answer: C. The extinguisher is defective and should be removed from service
The pressure indication alone does not establish that the required extinguishing agent is present.
An extinguisher found empty despite an apparent pressure indication must be removed from
service.
2. During annual maintenance, a rechargeable extinguisher is found with a damaged hose.
What is the most appropriate action?
A. Paint the damaged portion
B. Continue servicing because the cylinder is pressurized
C. Replace or properly repair the hose using an approved component
D. Remove only the nozzle
Answer: C. Replace or properly repair the hose using an approved component
,Damaged operating components can prevent proper discharge. Maintenance must restore the
extinguisher to a serviceable condition using components appropriate to the extinguisher.
3. Which fire class involves energized electrical equipment?
A. Class A
B. Class B
C. Class C
D. Class D
Answer: C. Class C
Class C fires involve energized electrical equipment. The extinguishing agent must be suitable
for the electrical hazard and should not create an unacceptable electrical-conduction hazard.
4. A technician is servicing a carbon dioxide extinguisher. Which method is most
appropriate for determining whether the extinguisher has lost the required charge?
A. Reading a pressure gauge
B. Weighing the extinguisher
C. Shaking the cylinder
D. Measuring the hose length
Answer: B. Weighing the extinguisher
Carbon dioxide extinguishers do not use a pressure gauge to determine charge quantity in the
same manner as stored-pressure dry chemical units. Weight is used to determine the agent
charge.
5. An extinguisher is located behind stored materials, making it difficult to reach quickly.
Which inspection element is deficient?
A. Agent compatibility
B. Accessibility
C. Hydrostatic pressure
D. Cylinder identification
Answer: B. Accessibility
Portable extinguishers must be readily accessible and available for use. Obstructions can delay
emergency response.
6. Which condition is most likely to require immediate corrective action during an
inspection?
,A. A clean cylinder with a readable label
B. A properly mounted extinguisher with an intact seal
C. A missing or broken tamper indicator
D. A current maintenance tag
Answer: C. A missing or broken tamper indicator
A missing or broken tamper indicator can indicate that the extinguisher has been used or
tampered with and requires further evaluation.
7. What is the primary purpose of the inspection of a portable fire extinguisher?
A. To completely disassemble the extinguisher
B. To verify that the extinguisher is available, accessible, properly located, and apparently
operable
C. To replace the extinguishing agent
D. To perform hydrostatic testing
Answer: B. To verify that the extinguisher is available, accessible, properly located, and
apparently operable
Inspection is primarily a visual or electronic check for readiness. It is different from
maintenance, which involves more detailed servicing.
8. A technician discovers corrosion that has materially weakened an extinguisher cylinder.
What should be done?
A. Polish the cylinder and return it to service
B. Apply another coat of paint
C. Remove the extinguisher from service and handle it according to applicable condemnation
and disposal requirements
D. Replace only the pressure gauge
Answer: C. Remove the extinguisher from service and handle it according to applicable
condemnation and disposal requirements
Severe corrosion can compromise cylinder integrity. A compromised cylinder should not simply
be cosmetically repaired and returned to service.
9. Which extinguisher classification is intended primarily for ordinary combustibles such as
wood, paper, and cloth?
A. Class A
B. Class B
C. Class C
D. Class D
, Answer: A. Class A
Class A hazards involve ordinary combustible materials.
10. Which extinguishing agent is generally associated with Class D fires?
A. Water
B. Carbon dioxide
C. Specialized dry powder
D. Ordinary foam
Answer: C. Specialized dry powder
Class D fires involve combustible metals. Specialized agents are selected according to the
particular metal involved.
11. A technician is preparing to recharge a rechargeable extinguisher. Which information is
especially important before selecting the recharge agent?
A. The color of the mounting bracket
B. The manufacturer's identification and specified agent
C. The building's paint color
D. The date of installation only
Answer: B. The manufacturer's identification and specified agent
Recharge materials must be compatible with the extinguisher and appropriate to its listing and
manufacturer's requirements.
12. What is the principal danger of mixing incompatible dry chemical agents?
A. The extinguisher becomes lighter
B. The mixture may become ineffective or cause chemical problems within the extinguisher
C. The hose automatically becomes longer
D. The cylinder becomes nonconductive
Answer: B. The mixture may become ineffective or cause chemical problems within the
extinguisher
Different dry chemical formulations are not automatically interchangeable. Compatibility must
be established before recharging.
13. A technician removes a stored-pressure extinguisher from service for maintenance. What
should be done with the hazard while the extinguisher is unavailable?
