but failing that NR's got the right idea ^^ fire extinguishers are always useful
just know your fire, memorise that fire triangle and the quicker you tackle the fire, the easier it is to tame, start lots of fires (as all good preppers should
) and get used to how it works, those reasons that make it hard to start a fire, can be used to stop a fire too ^^
