Advice on fire extinguishers overcharging in hot car
A question/expertise needed from the group. I put a Halguard (Halon replacement) fire extinguisher inside the Gladiator. Truck is parked outside in sun, not covered. Happened to look at gauge on a hot day, 100 degrees plus and it was in the Red, the 'overcharged' area. Took temperature on extinguisher and it was 123 degrees.
Left it in garage and next morning was in the green zone on gauge and was 77 degrees. Also have Halguard extinguisher on my Manx and noticed a very small amount of say spittle? on paint under discharge area. The Manx is parked in the garage.
So, question is, can the extinguisher discharge itself if heat gets too ambient temperature high? How would one ever keep a charged extinguisher in a car or hot area without having to worry about heat build-up discharging it.
The nightmare of an extinguisher going off inside a car is troubling.
Thanks for the advise and thoughts

We used to have a 25 pound ABC fire extinguishers in all of the city’s police cars....heat never did anything to them. They were inspected annually and if used were recharged.
These were in the trunk though

Same here in the school bus. Never a problem. The bus sets out in the heat and cold.
I had one in my car for years, not a problem.

We had an abc one blow in an RV in the desert, once but it was 30+ years ago

Look on the bottle of the fire extinguisher as it may have a heat rating on it. I would think that you would be ok with the heat as long as the gauge isn't pegged, and as long as it's not one of the recalled Kidde's with the crap plastic valves.

JMO, I would NEVER have a Halon type system in a close quarters area. If it goes off NO MORE AIR!!

It's not Halon gas. It's a much safer firefighting chemical.

If you're worried about a cannister bursting from the heat, you could also get a non-pressurized fire extinguisher. These Element sticks are really cool, and perfect for vehicles. I have several.
I'd make sure the extinguisher out of direct sunlight. That can really cause things to heat up.
I've had a dry chem go off in a vehicle. The nozzle was pointed at the floor and it was a short burst while the vehicle was stationary. An eight year old hit the lever and the safety pin wasn't in. A little vacuum work and you would never know it was there. If the vehicle was at speed and the whole cylinder emptied it might have been different.This message has been edited.
