Buying a Fire Extinguisher For A Vehicle: Tips & Advice

Here’s a product we hope you never have to actually use: a fire extinguisher for your car, RV or truck!

While no states require passenger vehicles to carry a fire extinguisher (in the United States), it may be a smart move to have one anyway.

That’s especially true for recreational vehicles, large trucks or even older passenger cars.

To get advice on buying the best car fire extinguisher, we interviewed fire safety officials from three counties across the country. We got their buying tips on what to look for when considering a fire extinguisher. Then we poured over third-party research that compared extinguisher safety.

After all that research, here is some advice and tips on buying a fire extinguisher:

• Fire extinguishers are rated A, B and C. A is for wood, paper, trash and some plastic fires. B is for flammable liquids. C stands for fires caused by energized electrical equipment. Hence, the most popular fire extinguishers for the home are rated ABC for all three types of fires. For vehicles, you’ll mostly see fire extinguishers that are 5BC.

• The second number next to the letter refers to water equivalency (A, where 1 = 1.25 gallons)) and square footage of coverage (B). Hence, a fire extinguisher that is rated 1A10BC covers all fire types, is equivalent to 1.25 gallons of water and covers 10 square feet of fire.

• Make sure the fire extinguisher is UL rated. All the recommended products in this article have a UL rating.

•  Always point the fire extinguisher at the base of the fire, not the top!

• When it comes to vehicle fires, if you have time, turn off the engine to keep fuel from flowing to the fire.

• The best fire extinguishers have a pressure gauge. Make sure the gauge is always in the green area—check this when you first get the extinguisher, as some extinguishers may accidently discharge during shipping. (Yes, you can have a used fire extinguisher recharged by a local fire equipment supply company).

• Yes, some fire extinguishers are rechargeable after use. This can be done by a fire equipment supply company or (in some areas) a local fire department.

• Vehicle fire extinguishers are much like those designed for the home, just smaller in capacity. That’s make them easier to mount in a vehicle. 

Based on our research, here are our top picks for fire extinguishers for cars:
