standard co2 fire extinguishers, how can you tell your one is safe ? cannisters, we all know many that use them, but, is a new standard one free from chemicals, do they have to be emptied first? then refilled? how can you tell if you have one that is ok? signs, codes, prints on bottles? will they give you a true idea to what you have and if it is ok to use? are there any bottle stamps that will let you know you have a safe bottle?
