The 6 sample questions as a list
  1. You are advancing a hoseline with your crew when a chief officer from another company tells you to go ladder the roof. What should you do?

    A) Leave the line and ladder the roof, since the chief outranks your officer
    B) Ignore the order and keep working, since he is not your direct supervisor
    C) Explain your current assignment and who gave it, and let the officers resolve it
    D) Finish advancing the line, then go to the roof without telling your officer
    C) Explain your current assignment and who gave it, and let the officers resolve it

    Unity of command means you report to one supervisor, so you tell the chief what you are doing and let the officers sort out the change. Quietly leaving your crew, even on a higher-ranking order, is freelancing and breaks accountability.
    Fire Service Organization
  2. In US firefighter fatality studies, what has in most years been the leading cause of on-duty deaths?

    A) Burns and smoke inhalation inside burning structures
    B) Vehicle crashes while responding to or returning from calls
    C) Structural collapse during interior firefighting operations
    D) Sudden cardiac events brought on by exertion and stress
    D) Sudden cardiac events brought on by exertion and stress

    Heart attacks, usually triggered by heavy exertion and stress in members with underlying heart disease, lead the list in almost every year. Vehicle crashes are a major non-medical cause, but cardiac deaths lead.
    Firefighter Safety & Health
  3. After kneeling on a hot floor, a firefighter gets a knee burn through turnout gear that shows no visible damage. What is the most likely explanation?

    A) The outer shell reflected radiant heat inward toward the knee
    B) The gear's outer shell ignited briefly, then self-extinguished
    C) Radiant heat passed through the reflective trim at the knee
    D) Compression squeezed the insulating air out of the thermal layer
    D) Compression squeezed the insulating air out of the thermal layer

    Where gear is pressed against the body, such as knees or shoulders under SCBA straps, the trapped air in the thermal barrier is squeezed out and heat passes through much faster. Soaked gear can add steam burns, but compression is the key factor when kneeling.
    Personal Protective Equipment
  4. A wooden chair near a fire is heated until it gives off flammable gases, which mix with air and burn. What process produced those gases?

    A) Vaporization
    B) Sublimation
    C) Oxidation
    D) Pyrolysis
    D) Pyrolysis

    Pyrolysis is the chemical decomposition of a solid by heat, releasing flammable gases that are what actually burn. Vaporization is the liquid-fuel counterpart, a physical change rather than a chemical breakdown.
    Combustion & Heat Transfer
  5. A downtown building has brick exterior bearing walls, wood floor joists and a wood roof. Which construction type is it?

    A) Type II (noncombustible)
    B) Type IV (heavy timber)
    C) Type III (ordinary)
    D) Type V (wood frame)
    C) Type III (ordinary)

    Type III combines masonry exterior walls with wood interior framing, and its signature hazard is fire spread through concealed spaces such as the cockloft. Heavy timber also has masonry walls, but with large-dimension wood members and few concealed spaces.
    Building Construction
  6. An extinguisher is rated 2-A:10-B:C. What does the 2 in 2-A mean?

    A) It holds 2 gallons of extinguishing agent in its cylinder
    B) It can put out roughly 2 square feet of burning Class A fuel
    C) It discharges its agent for roughly 2 minutes in total
    D) Capacity on ordinary combustibles equal to 2.5 gallons of water
    D) Capacity on ordinary combustibles equal to 2.5 gallons of water

    Each A unit equals 1.25 gallons of water, so 2-A matches 2.5 gallons. The square-foot meaning belongs to the B number, which roughly shows the flammable-liquid area a non-expert could put out.
