Study Notes
Vehicle Fires: Dangers and Precautions
- Sealed cylinders and containers in vehicles can become projectiles when over-pressurized by heat, potentially causing serious injuries.
- Modern vehicles are composed of over 50% plastic, producing more toxic smoke and gases compared to building fires.
- Various fuel systems are present in vehicles today, including gasoline, diesel, propane, CNG, LNG, and hybrid batteries. Heat can cause gasoline tanks to rupture and may trigger BLEVE in pressurized gas cylinders.
- Airbags remain charged for 30 seconds to several minutes post battery disconnection, posing injury risks to firefighters during deployment.
Vehicle Firefighting Safety Practices
- Maintain safe distances: avoid standing directly in front of, behind, or near the vehicle tires.
- Approach vehicle fires from upwind and utilize SCBA along with full PPE.
Fire Stream Selection
- Officers must choose an appropriate size and type of fire stream based on the fire's scale.
Challenges in Vehicle Fires
- Gaining access to the fire's seat is the primary challenge.
- Trunk access strategies include looking for car keys, using tools like a Haligan or flat-headed axe to manipulate locks.
- Accessing the hood may require releasing a secondary latch from inside the vehicle or knocking down fires through the grille.
Vehicle Fire Overhaul Procedures
- Overhaul after a vehicle fire involves:
- Disconnecting the battery, if it remains intact.
- Cooling any exposed fuel tanks and sealed cylinders.
- Stabilizing or chocking the vehicle.
- Ensuring the trunk is opened and checked for any remaining fire.
Documentation Requirements
- Complete incident reports must include:
- Owner information (name, address, phone).
- Vehicle details such as make, model, year, VIN, and tag number.
