Sample Fire Prevention and Protection questions

Try each one before opening the answer. Original questions written to the official exam objectives.

  1. Question 1

    A pre-action sprinkler system is often used where:

    • ACooking fires are likely
    • BPipes could never freeze and damage isn't a concern
    • CAccidental water discharge would be very costly
    • DOutdoor storage yards have no buildings
    Show answer and explanation

    Answer: C) Accidental water discharge would be very costly

    • AIncorrect. That's a kitchen system.
    • BIncorrect. Wet pipe is common there.
    • CCorrect. It needs a detection event before water enters pipes.
    • DIncorrect. Sprinklers serve buildings.

  2. Question 2

    Under 29 CFR 1910.106, what is the maximum quantity of Category 1, 2, or 3 flammable liquids that may be stored in a single storage cabinet?

    • A25 gallons
    • B30 gallons
    • C120 gallons
    • D60 gallons
    Show answer and explanation

    Answer: D) 60 gallons

    29 CFR 1910.106(d)(3)(i) limits a flammable liquid storage cabinet to 60 gallons of Category 1, 2, or 3 liquids. The 120-gallon limit applies only to Category 4.

    • AIncorrect. 25 gallons is not the cabinet limit. Under 1910.106(d)(3)(i), a cabinet may hold up to 60 gallons of Category 1, 2, or 3 liquids.
    • BIncorrect. 30 gallons is too low. The standard allows up to 60 gallons of Category 1, 2, or 3 liquids per cabinet.
    • CIncorrect. 120 gallons is the cabinet limit for Category 4 flammable liquids only, not for Categories 1 through 3.
    • DCorrect. 1910.106(d)(3)(i) says no more than 60 gallons of Category 1, 2, or 3 flammable liquids, nor more than 120 gallons of Category 4, may be stored in a storage cabinet.

  3. Question 3

    Portable extinguishers weighing 40 lb or less should generally be mounted so the top is no higher than:

    • A5 feet above the floor
    • B8 feet above the floor, out of reach of vandals
    • COn the floor only, with no mounting
    • D12 inches above the floor
    Show answer and explanation

    Answer: A) 5 feet above the floor

    • ACorrect. Heavier units are mounted lower.
    • BIncorrect. That's too high.
    • CIncorrect. They should be mounted.
    • DIncorrect. That's lower than generally required.

  4. Question 4

    Autoignition temperature is the lowest temperature at which a substance:

    • AFreezes
    • BGives off vapor
    • CBoils
    • DSelf-ignites
    Show answer and explanation

    Answer: D) Self-ignites

    • AIncorrect. That's freezing point.
    • BIncorrect. That's near flash point.
    • CIncorrect. That's boiling point.
    • DCorrect. No external ignition source is needed.

  5. Question 5

    The fire tetrahedron adds which element to the fire triangle?

    • AWater vapor
    • BCarbon dioxide
    • CNitrogen gas
    • DChain reaction
    Show answer and explanation

    Answer: D) Chain reaction

    • AIncorrect. That isn't part of the model.
    • BIncorrect. That's a product or extinguishing agent.
    • CIncorrect. Nitrogen isn't an element of fire.
    • DCorrect. Fuel, heat and oxygen are the others.

  6. Question 6

    Bonding and grounding containers during flammable liquid transfer controls:

    • AStatic discharge
    • BLiquid spills
    • CVapor toxicity
    • DHeat stress
    Show answer and explanation

    Answer: A) Static discharge

    • ACorrect. It prevents static sparks.
    • BIncorrect. That needs containment.
    • CIncorrect. That needs ventilation.
    • DIncorrect. That isn't related.

  7. Question 7

    Water is the best extinguishing agent for:

    • AClass C fires
    • BClass A fires
    • CClass D fires
    • DGrease fires
    Show answer and explanation

    Answer: B) Class A fires

    • AIncorrect. Water conducts electricity.
    • BCorrect. It cools ordinary combustibles.
    • CIncorrect. Water can react with metals.
    • DIncorrect. Water can spread grease fires.

  8. Question 8

    A flammable solvent used in a mixing room gives off vapors with a vapor density greater than 1 (air = 1). Which fire hazard does this property most directly create?

    • AVapors can flow along the floor and be ignited by a spark or flame some distance from the point of release
    • BVapors rise and collect near the ceiling, making overhead light fixtures the main ignition concern
    • CVapors stay at the release point above the upper flammable limit, so they cannot be ignited
    • DVapors spread evenly through the room, so floor-level exhaust has no advantage over ceiling exhaust
    Show answer and explanation

    Answer: A) Vapors can flow along the floor and be ignited by a spark or flame some distance from the point of release

    Vapors with a vapor density above 1 sink and can travel along the floor or ground to a distant ignition source. The resulting flame can then flash back to the source.

    • ACorrect. OSHA notes that heavier-than-air vapors may travel along the ground and be ignited by open flames or sparks far from where the material is handled.
    • BIncorrect. That describes vapors lighter than air (vapor density less than 1). Vapors denser than air sink and collect in low areas such as pits, trenches and along the floor.
    • CIncorrect. Vapor density has nothing to do with the flammable limits. As the vapors spread, they mix with air and can pass through the flammable range.
    • DIncorrect. Heavier-than-air vapors build up near the floor, which is why exhaust pickup at floor level works well for these materials.

  9. Question 9

    During a two-hour delivery, a warehouse supervisor wants to stage pallets along one side of an exit access aisle, leaving a 30-inch clear path. Under 29 CFR 1910.37, how should the safety professional respond?

    • ANot permitted, because no materials or equipment may be placed in an exit route, even temporarily
    • BPermitted, because the remaining clear path is wider than the 28-inch minimum width for exit access
    • CPermitted, as long as an attendant stays at the pallets for the whole two-hour delivery
    • DPermitted, if the aisle is temporarily marked 'Not an Exit' until the pallets are removed
    Show answer and explanation

    Answer: A) Not permitted, because no materials or equipment may be placed in an exit route, even temporarily

    29 CFR 1910.37(a)(3) requires exit routes to be free and unobstructed and bans placing any materials or equipment in them, permanently or temporarily. Meeting the 28-inch minimum width doesn't create an exception.

    • ACorrect. 1910.37(a)(3) says exit routes must be free and unobstructed, and no materials or equipment may be placed in the exit route, either permanently or temporarily.
    • BIncorrect. The 28-inch minimum in 1910.36(g)(2) sets how wide an exit access must be. It doesn't allow storage in the route, and 1910.37(a)(3) still bans placing materials there.
    • CIncorrect. The standard has no exception for attended or short-term obstructions. Temporary placement is specifically banned.
    • DIncorrect. Under 1910.37(b)(5), 'Not an Exit' marking is for doorways or passages that could be mistaken for an exit. It can't be used to turn a required exit route into a storage area.

  10. Question 10

    The most common type of automatic sprinkler system is:

    • ADry pipe
    • BWet pipe
    • CDeluge
    • DPreaction
    Show answer and explanation

    Answer: B) Wet pipe

    • AIncorrect. Used where freezing is a concern.
    • BCorrect. Pipes are filled with water.
    • CIncorrect. Used for high-hazard areas.
    • DIncorrect. Used where water damage is a concern.
