PSA: Fire extinguisher

Halon extinguishers cost out the ying yang now, but I wonder if they can be refilled if used? I looked in the FAQ's for the element extinguishers and it appears they are a one and done. @HankRearden very sorry for your troubles, but despite the mess, it looks recoverable.
Correct, the Element extinguishers are one and done. No ability to stop them even once your struck the top of it. However, from a size, weight and ’mess’ factor, it’s tough to beat them!
