Historical ones didn't use that code system, heh. I think it also might be a specifically US thing; I'll have to look into it
A '''fire extinguisher''' is a handheld, typically cylindrical, device used to extinguish small [[fire]]s. Such devices contain a fire-suppressive agent, typically under pressure, and are used by spraying this suppressive agent over the base of a fire, smothering the fire out. Fire extinguishers are typically used in an emergency, and should not be wasted on routine, controlled fires (such as a [[campfire]]).
