Study Notes
General Hazards and Safety Considerations
- Energy absorbing bumpers use gas and fluid-filled cylinders that can develop high pressure when heated, leading to sudden release and potential injuries, with bumpers capable of traveling up to 25 feet.
- Batteries pose risks of explosion, flammability, toxicity, and electrical shock; avoid contact with battery components.
- Hold-open devices on trunk hatches and engine hoods may incorporate springs or gas cylinders, which can fail or rupture if heated, resulting in explosive openings.
- Releasing latches on hot compartments requires sufficient clearance to prevent injury from sudden openings.
- Approach fires in the trunk or cargo area with caution, as contents may include toxic and flammable materials; prepare for hazardous outcomes.
- Fuel tanks, made of sheet metal or plastic, can rupture or burn-through, potentially causing rapid flash fires; do not remove gas caps from pressurized tanks.
- Avoid directing water streams into pressurized tanks to prevent burning fuel from spewing out of the fill opening.
- Well-sealed vehicle interiors can cause vent-limited fires that may intensify when fresh air is introduced; exercise caution when entering or ventilating the vehicle.
- Always have a charged handline ready before entering a vehicle, and ensure at least one team member is equipped with forcible entry tools for safe access.
- Tires or split rims exposed to fire may explode, posing risks of sudden drops in vehicle stability; approach the vehicle from the front or rear for added protection against flying debris.
- Air suspension systems in larger vehicles, such as buses, can fail under heat, resulting in the vehicle dropping unexpectedly.
- When rescuing trapped individuals, first apply water to protect patients; if no rescue is needed, cool the area around fuel tanks, especially if they contain LPG or CNG, to prevent fires.
