I have no idea Google it
You can ask the fire department?
They sell them there, but to my knowledge they don't recycle or recharge used extinguishers. I believe you need a form of safety certification to recharge them. Empty ones can be recycled at metal recycling centers. (Sometimes they must me crushed or cut apart)
Don't know why asking me about fire extinguishers I do not know if Home Depot recycle them used to be a place on Congress right off of Ben White going south on the right where the first things are company some of them they would take
