Re: Leap Out And Let It Burn
Save the heroics for people who are trained and equipped to deal with burning stuff on a large scale. Unless you're a fireman, that isn't you, Mister I-Did-The-Annual-Fire-Safety-Training-Course. Blundering into a burning data centre with the wrong extinguisher is going to earn you a roasting and two lungs full of Halon/FM200.
I've done multiple Fire Warden type courses, two of which were the full blown two day, lets start a fire and practise putting it out safely on day two, courses. In both of those (one back when I was in Scouts, many years ago) we didn't get to play with fire extinguishers, but that didn't really matter, because the subject of the courses was basically "here are the types of extinguisher, and the types of fire they may slow down slightly, pray to whatever God you hold dear that you never need them, and if there is fire raise the alarm and get the fuck out"
My Grandfather was a firefighter with the RAF, my Mother learned from him what to do in a house fire, and she taught me. It really isn't complicated (although I am fortunate enough to not know how difficult it can be first hand), know your routes out, the main route, the secondary route when the main route is blocked, and the "oh fuck" route when all else fails.
