Study Notes
Vehicle Fires: Dangers and Precautions
Sealed Cylinders/Containers
- Over-pressurization due to heat exposure can cause projectiles to fly, resulting in penetrating injuries and fractures
- Examples of sealed cylinders/containers include shocks, struts, shock absorbing bumper mounts, drive shafts, and gas-charged hood supports
Plastics in Modern Vehicles
- Modern vehicles are made of more than 50% plastic
- Smoke and gases from vehicle fires are often more toxic than those found in building fires
Fuel Systems
- Vehicles can be fueled by gasoline, diesel, propane, compressed natural gas, liquefied natural gas, batteries/hybrid, and others
- Gasoline tanks can rupture due to over-pressurization from heat exposure
- Propane, CNG, and LNG cylinders can BLEVE (boiling liquid expanding vapor explosion)
- Batteries from hybrids have additional Hazmat considerations
- Firefighters should not cut the large, orange-colored electric cables on electric/hybrid vehicles
Airbags
- Airbags remain activated and charged via a capacitor
- Airbags can remain charged from 30 seconds up to several minutes after the battery is disconnected
- Firefighters in front of a discharging airbag are likely to be injured
