How to Choose and Use a Car Fire Extinguisher？

Car fires can spread quickly, making a reliable fire extinguisher essential safety equipment for any vehicle. However, not all fire extinguishers are suitable for cars. Knowing how to choose the right fire extinguisher and how to use it correctly can save your car in a critical moment. Here's what you need to know.

How to Choose the Right Car Fire Extinguisher

The first step is to choose a fire extinguisher designed for the specific risks facing your vehicle. There are two main types of fires facing cars: electrical fires (from wiring or batteries) and flammable liquid fires (from gasoline, engine oil, or transmission fluid). This makes a multi-class BC or ABC fire extinguisher the best choice. BC fires can handle both electrical and liquid fires, while ABC fires can also handle fires involving solid materials (such as seat covers or carpets), offering a wider range of applications. If your car is a new energy electric vehicle, a dedicated lithium battery fire extinguisher will be necessary to meet your needs.

Size is important for both effectiveness and storage. A 1-2 kg fire extinguisher is ideal; it's lightweight and easy to handle in an emergency, while still having enough capacity to handle small to medium-sized car fires. Larger models (4 kg and above) are too bulky for most vehicles, taking up valuable space and are only suitable for large commercial vehicles.

Select compact, durable fire extinguishers. They should fit easily under seats, in the trunk, or in door compartments and not roll away. They should have a mounting bracket to prevent the extinguisher from moving while driving. Avoid using water-based extinguishers, which are ineffective against electrical or liquid fires and may damage vehicle components.

When to Use a Car Fire Extinguisher

Not all car fires require a fire extinguisher. If the fire is large (for example, the entire engine compartment is ablaze) or spreading rapidly, evacuate first. Call emergency services and retreat at least 50 meters to avoid the risk of an exploding fuel tank or battery.

A fire extinguisher is most effective only on small, controlled fires, such as:

Sparks from wiring or burning fuses in the dashboard.

A fire caused by a small oil leak in the engine compartment.

Smoldering seats or carpeting caused by a lit cigarette or electrical short. Correct Use

Stop safely: Pull the vehicle into an open area away from buildings, other vehicles, or dry vegetation. Turn off the engine and apply the parking brake.

Get the fire extinguisher: Quickly retrieve the fire extinguisher and pull the safety pin.

Determine the location of the fire: For an engine compartment fire, do not fully open the hood, as this will provide oxygen to the fire. A slight opening is sufficient for spraying. For an interior fire, partially open a door to restrict the flow of oxygen.

Check for re-ignition: After the fire is extinguished, observe the area for one or two minutes. If smoke or flames reappear, repeat the procedure; if the fire grows, evacuate.

Post-use procedures

After the fire is completely extinguished, do not attempt to drive the vehicle. Even a small fire can damage wiring or fuel lines, creating new hazards. Call a tow truck to take the vehicle to a repair shop to inspect for hidden damage. Immediately replace any used fire extinguishers to ensure a fully charged extinguisher is available for future trips. 

Choosing the right fire extinguisher can add important safety features to your driving. A small, properly fitted fire extinguisher is a low-cost investment that could save your vehicle, or even your life, in an emergency.
