  1. A worker on a construction site leaves an open gasoline can near a temporary heater. What should the F-03 fire guard do?

    Answer: Immediately require the can to be closed and moved at least 25 feet from any ignition source

    An open gasoline container near a heat source is an immediate fire hazard — the fire guard must require immediate correction.

  2. How should oily rags used with linseed oil or tung oil be stored on a construction site?

    Answer: In a covered metal container with water or sent for daily disposal

    Oily rags (especially with drying oils like linseed) must be stored in covered metal containers with water or disposed of daily to prevent spontaneous combustion.

  3. What is the purpose of a flame arrester in an approved safety can for flammable liquids?

    Answer: To prevent external flames from igniting vapors inside the can and causing an explosion

    Flame arresters prevent a flame from propagating back into the container by quenching it as it passes through a fine metal mesh.

  4. Under NYC Fire Code, where is the preferred location for bulk flammable liquid storage on a construction site?

    Answer: In a dedicated outdoor storage area away from the building and away from means of egress

    Bulk flammable liquid storage should be in a dedicated outdoor area separated from the building structure and all egress paths.

  5. What does the Lower Explosive Limit (LEL) represent for flammable vapors?

    Answer: The minimum vapor concentration in air at which the mixture can be ignited

    The LEL is the minimum concentration of flammable vapor in air that can sustain a flame — below this concentration the mixture is too lean to ignite.

  6. What is the correct way to transfer flammable liquids from a drum to a safety can on a construction site?

    Answer: Use an approved pump or self-closing faucet with the drum grounded and bonded to the receiving container

    Transfer must use approved equipment with bonding and grounding to prevent static discharge ignition, plus proper containment for spills.
