Can carbon dioxide fire extinguishers freeze in cold weather?

Other fire extinguishers resistant to freezing temperatures (down to -40 degrees F) are comprised of pressurized water with antifreeze, halon, halotron and CO2, and class D and other dry chemical extinguishers are also cold friendly.

Can I leave a fire extinguisher in a cold car?

Fire extinguishers can be stored horizontally if necessary and can also be stored in automobiles if the average temperature within the vehicle falls within the UL rating, which is usually -40 degrees to 120 degrees.

Can a CO2 fire extinguisher freeze?

As the CO2 gas is extremely cold when leaving the heavily pressurised extinguisher cylinder, there is a risk of freeze burn if the user touches the nozzle or pipe. More up to date models have a ‘frost free’ safety horn to prevent this. It can be very dangerous to use a CO2 extinguisher on a cooking fat fire.

Can fire extinguishers be stored below freezing?

Yes. According to experts a water-based extinguisher can freeze if the temperature drops below 40° F. Also at risk of freezing are foam-based extinguishers, like Class K. Experts say AFFF foam, FFFP foam and Class K (the type you might want for a BBQ), are all at risk below 40° F.

What temperature does a fire extinguisher freeze?

A fire extinguisher canister made with water mist and pressurized water—as well as AFFF foam, FFFP foam and class K extinguishers—will freeze when left out in temperatures below 40 degrees Fahrenheit.

What is the temperature of CO2 fire extinguisher?

CO2 suffocates the fire by the displacement/dilution of oxygen in the air. In addition to this, the extinguishing medium comes out at a temperature of -60°C which removes another key player in the fire triangle – heat.

What happens if a fire extinguisher freezes?

Why Freezing is a Problem

Let’s cut right to the chase: yes, some fire extinguishers will freeze in ambient temperatures below 40 F. This will render your fire extinguisher permanently unusable.

Where do you put a fire extinguisher in a garage?

The best location to mount a fire extinguisher in the garage is near the door. Fire extinguishers in business locations are also vital.

Why are fire extinguishers cold?

When you fire the extinguisher, you allow the gas to escape through the nozzle, and as it flows out it expands rapidly, doing work on the surrounding atmosphere in the process. As it does work its internal energy decreases, so it becomes colder.

How do you store extra fire extinguishers?

A modern fire extinguisher can be stored horizontally. The contents are under pressure, and the angle of storage will not cause the system to leak. Proper fire extinguisher storage includes using the appropriate mounting brackets, and being sure that you do not allow your extinguishers to freeze.
