  1. According to NFPA 10, how often must portable fire extinguishers receive an annual maintenance inspection?

    Answer: Once per year

    NFPA 10 requires a thorough annual maintenance inspection of all portable fire extinguishers to verify they are fully charged and operable.

  2. Which class of fire extinguisher is specifically designed for use on cooking oil and grease fires in commercial kitchens?

    Answer: Class K

    Class K extinguishers use a wet chemical agent designed specifically for high-temperature cooking oil and animal/vegetable fat fires found in commercial kitchens.

  3. What is the maximum travel distance to a Class B fire extinguisher in an area with a low-hazard flammable liquid occupancy?

    Answer: 75 feet

    NFPA 10 specifies a maximum travel distance of 75 feet to a Class B extinguisher for low-hazard flammable liquid areas.

  4. A fire extinguisher labeled '2-A:10-B:C' — what does the '2-A' rating indicate?

    Answer: It can extinguish twice the fire as a 1-A unit

    The numerical prefix in Class A ratings is a relative effectiveness rating, where 2-A extinguishes twice the fire area compared to a 1-A rated extinguisher.

  5. According to NFPA 10, when must a dry chemical extinguisher receive a 6-year internal examination?

    Answer: Every 6 years from the date of the last internal examination

    NFPA 10 requires dry chemical extinguishers to undergo internal examination every 6 years from the date of the last internal examination or hydrostatic test.

  6. Which type of portable fire extinguisher agent is most appropriate for use on Class D (combustible metal) fires?

    Answer: Dry powder (specific to metal type)

    Class D fires involving combustible metals require a specific dry powder agent matched to the burning metal type, as standard agents can react violently with some metals.

  7. Under NFPA 10, what minimum height must the handle of a portable fire extinguisher be mounted from the floor when the extinguisher weighs 40 pounds or less?

    Answer: 5 feet

    NFPA 10 requires that extinguishers with a gross weight of 40 lbs or less have their handle mounted no higher than 5 feet from the floor.
