It is a recently certified unit that was still "in use" until a couple months ago when we shut down our plant. Does that matter? Or is it still likely that some places wouldn't refill it? I mean, if it was still intended for use as a fire extinguisher then somebody would fill it, right?
I'm not sure where to find a replacement top for it that would have a standard shut-off valve instead of the pin/trigger top. Or if that's even possible. Obviously, the pressure would have to be bled off first. Is there any way to do this without spraying it all over the place? It all sounds a bit risky. I'm probably just better off spending the $$ on a new/used tank.
