Read the first 6 ERT Fire Safety & Suppression flashcards as text

  1. Which type of smoke detector is MOST effective at detecting slow, smoldering fires?

    Answer: Photoelectric smoke detector

    Photoelectric detectors use a light beam to sense large smoke particles produced by slow, smoldering fires more effectively than ionization detectors.

  2. What is the primary purpose of a fire watch in a facility?

    Answer: To continuously patrol for fire hazards when the automatic suppression system is impaired

    A fire watch is required by NFPA and OSHA standards when a building's fire protection system is out of service, ensuring a trained person actively monitors for fire.

  3. According to OSHA 29 CFR 1910.157, portable fire extinguishers must be visually inspected at minimum:

    Answer: Monthly

    OSHA 29 CFR 1910.157 requires employers to visually inspect portable fire extinguishers monthly to verify they are in place, fully charged, and unobstructed.

  4. What is the MOST important safety action before entering a smoke-filled space during an emergency?

    Answer: Don appropriate respiratory protection (SCBA or N95 at minimum)

    Smoke inhalation is the leading cause of fire-related deaths; donning respiratory protection before entering a smoke-filled space is the primary life-safety measure.

  5. Which fire behavior term describes the rapid transition from a localized fire to full room involvement?

    Answer: Flashover

    Flashover is the point at which radiant heat causes all combustible surfaces in a compartment to reach ignition temperature simultaneously, resulting in total room involvement.

  6. During a building evacuation due to fire, why should occupants close doors as they exit?

    Answer: Closed doors slow fire spread, reduce oxygen availability, and can reduce compartment temperatures significantly

    A closed door can reduce compartment temperatures from over 1,000°F to under 100°F, dramatically slowing fire spread and improving survivability for trapped occupants.
