A number of hazards can cause fires in cars, ranging from wiring malfunctions to fuel line leaks. This makes a car fire extinguisher an essential item. Maintenance prevents some, but accidents still occur. A car fire extinguisher allows you to act quickly, stopping fire from spreading and doing more damage. Knowledge of fire-susceptible areas under the hood and dashboard also assists with faster response. In addition to installing a fire extinguisher, have a fire blanket and first-aid kit as extra protection. It is always better to be over-prepared than to be caught unawares.
