Name two hazards commonly associated with vehicle fires and a mitigation tactic for each.

• A. Salvage potential and structural hazards; mitigation: keep safe distance and isolate the vehicle, disconnect battery when possible.
• B. Smoke color and noise level; mitigation: open all doors to vent.
• C. Ignition sources and vibrations; mitigation: park the vehicle.
• D. Fuel economy and emissions; mitigation: use shielding.

Answer: (D)

In a vehicle fire the main hazards to understand are exposure to toxic smoke and the risk of ignition or reignition from flammable fuels and energized electrical systems. Toxic smoke comes from burning plastics, upholstery, fluids, and other materials, delivering hazardous gases that can harm anyone nearby. A practical mitigation for this is to keep a safe distance and, if possible, isolate the vehicle so bystanders aren’t exposed and the fire doesn’t spread to other areas. The second hazard is ignition risk from fuel vapors and the vehicle’s electrical system; disconnecting the battery when safe reduces power to the system, cutting off a potential ignition source and helping prevent reignition or further electrical hazards. The other choices don’t reflect hazards specific to vehicle fires or appropriate, realistic mitigations for those hazards.
