    Default Tacoma, Wash. Fire Exam

    Below are some practice exam questions to help you study for the FSI test that will be used for the Tacoma, Washigton exam.

    1. When any substance burns, molecules of that substance enter a chemical reaction we call combustion. For this to occur, the molecules of the substance must be free to react. Molecules are usually only free to react when the molecules exist in the form of:
    (Fire Chemistry, pg 4)
    A) gas only
    B) gas or vapor
    C) vapor only

    3. This describes when the number of molecules leaving a liquid equals the number of molecules returning to the liquid:
    (Fire Chemistry, pg 4)
    A) conduction and convection
    B) point of equilibrium
    C) specific gravity as it relates to the general flammable nature of the fuel and pressure exerted above the air space

    4. Which of the following describes the ease with which the fuel evolves to a vapor:

    A) nature of validity
    B) equilibrium point of ignition
    C) volatility
    D) ignition migration

    5. Gasoline begins to release flammable vapors at:

    A) 45 F
    B) 45 F below zero
    C) 32 F below zero
    D) above 212F

    6. The cooling effect of water can easily quench a wood fire below its:
    (Fire Chemistry, pg 7)
    A) flash point only
    B) fire point only
    C) flash or fire point
    D) flash point, fire point, self-contained substance combustion

    A) external ignition
    B) auto-ignition
    C) explosive ignition range

    9. Oak wood has an ignition temperature of:

    B) a mixture of the flammable vapors and air, expressed as a byproduct, at which no ignition can occur
    C) a mixture of the flammable vapors and air, expressed as a percent, above or below which no ignition can occur

    11. In regards to explosive range, if a mixture is above the flammable range, this is referred to as:
    (Fire Chemistry, pg 8)
    A) continuous combustion
    B) vapor and equilibrium explosive range
    C) too rich
    D) too lean
