I am sure that's a great idea. Here is a little funny that you all might find interesting and it's on topic.
I have a 1964
boat. In it was one of the original fire extinguishers. It had been kept in the boat all the time. Even though the boat was stored in the garage. It was still exposed to the warm and cold temps of the midwest.
On night while dry docking in the garage with a buddy of mine, we decided (after a few adult beverages) and bet if the unit would still work. I bet yes and my friend bet no. Seemed like a pretty safe bet.
So, we fired it off and sure enough, it still worked!
I won the $1 bet, but then paid $10 to have the unit refilled and certified!
