  1. Which gas produced by fires is known as the 'silent killer' because it is odorless and colorless?

    Answer: Carbon monoxide (CO)

    Carbon monoxide is odorless and colorless, making it undetectable without a detector, and it causes more fire-related deaths than flames.

  2. What is the meaning of the term 'flashover' in a structural fire?

    Answer: The rapid transition where all combustible materials in a room ignite simultaneously

    Flashover is the near-simultaneous ignition of all combustibles in an enclosed space, typically occurring when temperatures reach 1,100°F (593°C).

  3. What should you do with a fire extinguisher after using it partially to fight a fire?

    Answer: Have it refilled or replaced immediately

    Even a partially discharged extinguisher must be recharged or replaced immediately because you cannot know if it will work adequately in the next emergency.

  4. In a high-rise building fire, occupants on unaffected floors are typically instructed to:

    Answer: Shelter in place unless directed otherwise by fire safety personnel

    High-rise fire protocols often call for shelter-in-place on unaffected floors because stairwells can become overcrowded and smoke conditions may be worse below.

  5. Which of the following best describes the 'fire triangle'?

    Answer: The three elements needed for fire: fuel, heat, and oxygen

    The fire triangle represents the three essential elements for combustion: fuel, heat, and oxygen — removing any one element extinguishes the fire.

  6. What is the safest way to exit a burning building if the stairwell is filled with smoke?

    Answer: Crawl low to the floor where air is cleaner and use an alternate stairwell

    Crawling keeps you below the heaviest smoke concentration, and seeking an alternate stairwell avoids committing to an impassable route.

  7. According to NFPA 1, what is the maximum travel distance to a portable fire extinguisher for Class A hazards in most occupancies?

    Answer: 75 feet

    NFPA 1 requires that portable fire extinguishers for Class A hazards be accessible within a maximum travel distance of 75 feet.
