  1. Under OSHA 1926.150, which type of fire extinguisher is appropriate for a Class B (flammable liquid) fire on a construction site?

    Answer: Dry chemical (BC or ABC rated) or CO2 extinguishers

    Class B fires involve flammable liquids and gases. Dry chemical (BC or ABC) and CO2 extinguishers are rated for Class B fires. Water should never be used on flammable liquid fires as it can spread the fire.

  2. Under OSHA 1926.150(e), what is the maximum travel distance a worker must have to reach a fire extinguisher for Class A hazards on a construction site?

    Answer: 100 feet

    OSHA 1926.150(e)(1) requires that fire extinguishers for Class A hazards be placed so workers do not have to travel more than 100 feet to reach them.

  3. Under OSHA 1926.24, what must a construction site fire prevention plan include?

    Answer: List of major fire hazards, procedures for handling and storing flammable materials, ignition source controls, fire protection equipment, and assigned responsibilities for maintaining equipment and controlling hazards

    OSHA 1926.24 requires a written fire prevention plan that addresses fire hazards, ignition source control, flammable material storage, fire protection equipment, and responsibilities for plan maintenance.

  4. Under OSHA 1926.152, quantities of flammable liquids greater than 25 gallons must be stored in what type of container or facility?

    OSHA 1926.152(b)(1) requires flammable liquids in excess of 25 gallons to be stored in an approved storage cabinet or in a room or detached building designed for flammable storage.

  5. What does the acronym PASS stand for when using a portable fire extinguisher?

    Answer: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side

    PASS stands for Pull the pin, Aim the nozzle at the base of the fire (not the flames), Squeeze the handle to discharge the agent, and Sweep the nozzle side to side at the base of the fire.

  6. Under OSHA 1926.34, what is the minimum clear width required for emergency egress routes on construction sites?
