planes would just bounce off thenput some of the millions and millions of used tires to good use
Take it to your local fire station and ask them if it is serviceable. If not but refillable they can direct U 2 a refill and refurbish company. They should also know how and or where it should be disposed if it is wasted.
as a firefighter u need to check the date and if it is older then 7 years i would trash it and get a new one. Also check for leaks on the bottom and all around it. Make sure the pin is still in and see if their is a date tag.

Hi there; Apart from looking at any pressure gauges, weighing the unit will tell you if there is still a full charge / propellant inside: the standard weight should be stamped on the cylinder somewhere. Check that the safety pin in the operating mechanism is in place, that the nozzle is clear and not blocked, and that there is no corrosion on the extinguisher body. As has been said before though, if you're in any doubt, have it checked by the local fire department. A fire extinguisher is one thing that you really don't want to fail on you at the last minute.
theres a gauge on it lol.. or should be. if the pressure needle is in the green area its good
