Fire Motor Vehicle

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 but deliberate car fires (arson) are increasing. There are approximately the same number of deliberate car fires as there are accidental car fires in the UK. It is common for joyriders to set fire to stolen cars: abandoned cars are commonly set on fire by vandals. Around two cars out of every thousand registered in the UK catch fire each year.

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. It is mandatory to carry an in-car fire extinguisher in some countries, such as Belgium, Bulgaria and Poland.[5]

From 2003 to 2007 in the United States, there were 280,000 car fires per year, which caused 480 deaths
