the Underwriters Laboratory label. The laboratory requires that extinguishers can be safely stored at minus-40 to plus-120 degrees, a standard that is sometimes posted on the extinguisher.But the laboratory also requires that extinguishers survive 175 degrees for seven days, which is not normally disclosed in product information. A quality, UL-listed extinguisher has a steel cylinder that is designed to withstand six times its normal pressure without bursting.
is the assurance I've been looking for.

I thank you!

Did you measure 175 in you car's interior? Wow! That's astounding! That would be quickly fatal. (You may be yanking my chain)

Did you have an extinguisher in that vehicle?

jzchen Okay, just trying to be helpful:

No need to resort to survivalist extremes. Kidde gives you the answer for their recommendation, it is 120°F

jzchen Couldn't find high temp limit on Kidde auto extinguisher for some reason, but did find this thread:

I agree that's obviously not the time to whack it.

HGB I've heard from various reliable sources that fire extinguishers should be whacked with a wooden or rubber mallet on the sides near the bottom.
Apparently the powder cakes up and then the extinguisher's performance is compromised.
It's a cheap insurance because even when the gauge shows that there's plenty of pressure it may not mean much.

The greenhouse effect. It's not something invented by environmental wackos. The interior temperature of a vehicle in sunlight can be expected to be much higher than the ambient temperature, whether that be 20° or 120°. I have had plastic objects literally deform in an enclosed vehicle.

Thus, the reason for this thread.
