Makes you think....

I have the same question 

[torredcuda]

Had an oven fire in my first house years ago, the oven had an issue with the timer and got stuck on overnight with a cake in it and about 2am the smoke alarms went off. Scares the crap out of you to wake up to flames filling your oven and smoke in the kitchen, after getting my brain working I was able to put it out with a small extinguisher while my sister in law called 911. Luckily the smoke detecters did their job and all we needed was a new oven but the wall behind it was very warm so it wouldn`t have been too long before the house caught fire. Most of you heard about my engine bay fire in my Barracuda and again I was lucky to have a couple large extinguishers handy or I would have lost my whole garage with everything in it, it was detached so the house would have been OK but would definitely been devastating to me. 

ALWAYS KEEP NUMEROUS FIRE EXTINGIUSHERS CHARGED AND READY !!!!!!!!!!!!!!!!!!!!!

I would imagine the fire extinguisher would have less pressure in the cold, gasses expand and contract.    as far as effecting longevity I am not sure it would effect it. but they are suppose to be inspected after a period of time.

This made me think of my fire extinguisher in the garage. It's not old ~7 ish years.


As it lives in a non temperature controlled environment, it does go through the terrible summer heat and cold of Canadian winters. Does that shorten the life of a fire extinguisher?

Your typical ABC type fire extinguishers are good from something like -50°C to 50°C. The temp itself doesnt really "shorten" the life of it, but the humidity is a bigger issue causing rust etc. If the needle is in the green your typically good. Keep the rust away, the nozzle clean and turn it upside down every once in a while and give it a good shake, keeps the dry chemicals "loose". I'm by no means  a fire extinguisher professional but that's some tips I've been told.
