  1. A carbon dioxide (CO2) fire extinguisher is being inspected. Which condition would require it to be removed from service?

    Answer: Loss of more than 10% of its listed weight

    NFPA 10 requires CO2 extinguishers to be removed from service and recharged if they have lost more than 10% of the net agent weight listed on the nameplate.

  2. What does the term 'hydrostatic testing' refer to in the context of portable fire extinguishers?

    Answer: Pressure testing the extinguisher cylinder with water to verify structural integrity

    Hydrostatic testing involves filling the cylinder with water and pressurizing it beyond operating pressure to verify the shell has no cracks, flaws, or leaks.

  3. Under NFPA 10, stored-pressure dry chemical extinguishers require hydrostatic testing at what interval?

    Answer: Every 12 years

    NFPA 10 requires stored-pressure dry chemical extinguishers to undergo hydrostatic testing every 12 years.

  4. A fire inspector observes that the inspection tag on an extinguisher shows the last inspection was 13 months ago. What is the correct action?

    Answer: Document the finding and require immediate annual maintenance

    NFPA 10 requires annual maintenance; an extinguisher with a tag showing over 12 months since the last inspection is overdue and must receive immediate maintenance.

  5. Which fire extinguisher class is rated for fires involving energized electrical equipment?

    Answer: Class C

    Class C extinguishers use non-conductive agents suitable for use on energized electrical equipment, preventing electrical shock to the operator.

  6. According to NFPA 10, what is the maximum travel distance to a Class A fire extinguisher in a light-hazard occupancy?

    Answer: 75 feet

    NFPA 10 allows a maximum travel distance of 75 feet to a Class A extinguisher in light-hazard occupancies.

  7. When inspecting a multipurpose dry chemical extinguisher, the inspector finds the pull pin is missing but the pressure gauge reads in the green zone. What is the correct action?

    Answer: Tag it out of service; missing safety devices require immediate correction

    A missing pull pin is a safety device deficiency that renders the extinguisher out of service under NFPA 10 until corrected.
