  1. How frequently must a hydrostatic test be performed on a stored-pressure dry chemical extinguisher?

    Answer: Every 12 years

    Stored-pressure dry chemical extinguishers require hydrostatic testing every 12 years per NFPA 10.

  2. An extinguisher with a '2-A:10-B:C' rating means it is rated for:

    Answer: 2 gallons of water equivalent for Class A, 10 square feet of flammable liquid for Class B, and electrical fires

    The '2-A' means the extinguisher has the Class A firefighting equivalent of 2.5 gallons of water; '10-B' means it can extinguish 10 square feet of Class B fire; 'C' indicates it is safe for use on electrical fires.

  3. What is the maximum floor area that a single 2-A rated extinguisher can protect?

    Answer: 11,250 sq ft

    Under NFPA 10, a 2-A extinguisher protects up to 6,000 square feet under light hazard occupancy, but one 'A' unit covers 3,000 sq ft up to a maximum of 11,250 sq ft per extinguisher.

  4. Which condition would require a fire extinguisher to be immediately removed from service?

    Answer: A broken tamper seal with the pull pin still in place

    A broken tamper seal indicates the extinguisher may have been used or tampered with, requiring immediate removal for inspection and possible recharging.

  5. For a high-hazard occupancy, what is the maximum travel distance to a Class B fire extinguisher?

    Answer: 30 feet

    NFPA 10 requires a maximum travel distance of 30 feet to Class B extinguishers in high-hazard occupancies.

  6. A carbon dioxide (CO2) extinguisher is most effective against which type of fire scenario?

    Answer: Small Class B and C fires in enclosed spaces

    CO2 extinguishers work by displacing oxygen and are most effective on small flammable liquid (B) and electrical (C) fires, particularly in enclosed areas where the gas can concentrate.

  7. When mounting a fire extinguisher, NFPA 10 requires that extinguishers weighing 40 lbs or less have their handles no higher than:

    Answer: 5 feet from the floor

    NFPA 10 specifies that extinguishers with a gross weight not exceeding 40 lbs shall be installed so the handle is no higher than 5 feet above the floor.
