Can fire extinguishers explode in the sun

Yes. When fire extinguishers are kept too close to stoves, fireplaces, or power generators, they can become overheated. Temperatures between 40 and 120 degrees Fahrenheit are suggested for keeping fire extinguishers. The valve, tank, or line could be destroyed if exposed to extreme temperatures.

No. Fire extinguishers are tough but harsh UV rays will dry out the hose and other plastic parts. Direct sun will fade the labeling, which may not seem like a big deal but in a safety inspection, that extinguisher would fail.

What happens when a fire extinguisher runs out of pressure?

The extinguisher will eventually run out of pressure, preventing an explosion. Safety valves, or ruptured discs, are included with nearly all tanks that hold pressure. If a fire extinguisher gets under extreme heat, it may only melt the plastic valves allowing the gas to escape, and not explode.

What makes a fire extinguisher less capable?

There are other ways to render a fire extinguisher less capable. For instance, blockage by the extinguishing agent inside hoses, springs, gaskets, and O-rings after being partially used can make it less effective.

Can a chemical fire extinguisher freeze?

Chemical fire extinguishers are not guaranteed to resist freezing because they may contain water solutions that cannot be enhanced by anti-freezing ingredients. This means you must not allow an extinguisher to sit in freezing temperatures for several hours or days. The water inside the container will expand and put it under strain.
