What is a potential hazard when releasing latches on trunk rear hatches or engine hoods?
What is a potential hazard when releasing latches on trunk rear hatches or engine hoods?
- Hinge failure may result in sudden closure.
- Freezing temperatures may cause the latch to stick.
- Corrosion may weaken the latch mechanism.
- Excessive pressure may cause explosive force. (correct)
Why should one avoid directing a hose stream into a fuel tank?
Why should one avoid directing a hose stream into a fuel tank?
- It may create a vacuum that implodes the tank.
- The hose stream may freeze the fuel, leading to a blockage.
- It can dilute the fuel, making it less effective in fires.
- It can cause pressurization and result in burning fuel discharge. (correct)
What should be done to ensure personal safety when dealing with heat-exposed gas cylinders?
What should be done to ensure personal safety when dealing with heat-exposed gas cylinders?
- Regularly inspect the cylinders for leaks to ensure safety.
- Allow sufficient clearance and maintain a safe distance. (correct)
- Quickly open hatches to vent gas before it can expand.
- Stand close while releasing latches to minimize exposure.

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.
