  1. Class K fire extinguishers are specifically designed for which type of fire?

    Answer: Cooking oils and fats in commercial kitchens

    Class K fires involve cooking oils and animal or vegetable fats at high temperatures, typically found in commercial kitchen cooking equipment. Class K extinguishers use a wet chemical agent.

  2. What does a '20-B' rating on a fire extinguisher mean?

    Answer: The extinguisher can cover 20 square feet of burning liquid

    The numerical rating before 'B' indicates the approximate square footage of a flammable liquid fire that a trained operator can extinguish. A 20-B rating means approximately 20 square feet.

  3. Which type of fire extinguisher agent leaves no residue and is safe for use in areas with sensitive electronic equipment?

    Answer: Carbon dioxide (CO2)

    CO2 extinguishers discharge a clean gas that leaves no residue, making them ideal for electrical panels and sensitive equipment. Dry chemical leaves powder residue that can damage electronics.

  4. When inspecting a portable fire extinguisher before a hot work shift, which condition would require the extinguisher to be immediately removed from service?

    Answer: The pressure gauge needle is in the red (undercharged) zone

    A pressure gauge in the red zone indicates the extinguisher is undercharged and may not function properly. It must be removed from service and recharged or replaced immediately.

  5. During torch operations on a roof, which extinguisher class is MOST critical to have immediately accessible?

    Answer: Class B:C rated, because propane fuel and potential electrical hazards exist

    Torch operations use propane (Class B flammable gas) and may have electrical equipment nearby (Class C). A B:C or A:B:C rated extinguisher covers both hazards.

  6. What is the maximum travel distance to a fire extinguisher from any point in a hot work area, per NFPA 51B?

    Answer: 30 feet

    NFPA 51B requires that a fire extinguisher be located within 30 feet of the hot work operation so the fireguard can reach it immediately in an emergency.
