Vehicle fire

A car engine fire on the Massachusetts Turnpike.

A vehicle fire is an undesired conflagration (uncontrolled burning) involving a motor vehicle. Also termed car fire or auto fire, it is one of the most common causes of fire-related property damage.

Causes

A motor vehicle contains many types of flammable materials, including flammable liquids like gasoline and oil as well as solid combustibles such as hose. Fuel leaks from ruptured fuel lines also can rapidly ignite, especially in petrol fuelled cars where sparks are possible in the engine compartment. Fires with casualties have been caused by ozone cracking of nitrile rubber fuel lines for example.

Vehicles house multiple potential sources of ignition including electrical devices that may short circuit, hot exhaust systems, and modern car devices such as air bag detonators.

In the UK, accidental car fires are declining[1] but deliberate car fires (arson) are increasing. Most car fires in the UK are arson. It is common for joyriders to set fire to stolen cars: abandoned cars are commonly set on fire by vandals. Around two cars out every thousand registered in the UK catch fire each year.[2][3]

It is often the case in accidental auto fires that the bulk of the fire is (at least initially) contained in the engine compartment of the vehicle. In most vehicles, the passenger compartment is protected from engine compartment fire by a firewall. However, in case of arson, the fire does not always start in the interior or spread there.

There are about 280,000 car fires per year in the USA, causing 480 deaths.[4]

History

While some cases of deliberate car fires are isolated incidents, committed clandestinely, the practice is publicly performed by either rioters and revelers, with little to no retribution. Some tragic vehicle fires have received wide publicity, some evidently due to accident or mechanical or electrical problems, and other due to crimes.

The recommended action in case of car fire is:[13][14]

The last is important due to the risk of explosion and the toxic fumes emanating from vehicles fires. Inhalation of toxic fumes is the most common form of fire-related death. Also, the liquid fuels (oil and petrol) that are present in most cars, if burning, can be difficult and hazardous to extinguish; it is highly unsafe for untrained persons to attempt this.

Opening the hood (bonnet) of a car which may be on fire is especially dangerous, as it allows a rapid and significant surge of air into the engine compartment, which may cause a rapid increase in fire intensity. Some countries require the carrying of a fire extinguisher. This should not be seen as overriding the advice above. It has been suggested that, when using a fire extinguisher on an engine fire, the extinguisher should be fully discharged through the gap created by simply releasing (but not lifting) the hood, and then the car should be left until the fire crew have pronounced it safe. As with all fires, residual hot spots may cause the fire to flare up again when fresh oxygen is supplied.
