    Default Fire tetrahedron question

    The fire tetrahedron is commonly used to explain fire behavior to the lesser knowledgeable peons entering the fire service. When you remove one component of said tetrahedron , the fire will go out. Which component (also referred to as a leg by the lesser informed) is your favorite to remove? And said components may be referred to "reducing agent" "oxidizing agent" "temperature" and of course "chemical chain reaction" or the far cruder version of oxygen, fuel, heat, and the flame interface. What say you ?

    I use heat, fuel, oxygen, and chemical reaction, that being how I heard it explained.

    Adding the chemical reaction to the fire triangle is simple, and covers how dry chem extinguishers work (ie, by interrupting the reaction, as they clearly don't remove heat or fuel, and only marginally oxygen).

    I use it with fourth graders during our FPW visits.

    I like spray water so I guess that means heat. But I also enjoy breaking things. What say you?

    I really think we've been approaching this whole firefighting thing wrong. It is obvious that the safest way to stop fire is by removing the fuel. Think about it. It's the only way to stop fire before it actually starts. Replace all the apparatus with bulldozers and demo all of the buildings in your response area. Bingo, no more structural fires.

    How's that for flawless logic?

    PS The bulldozers will NOT need their own pumps.

    Sounds like the first Haddon's Strategies.

    But why not equip the dozers with pumps, water tanks and ladders as that way you would be prepared for anything. We could call them Qozers. And possibly staff them with 8 personnel each.

    Actually, the safest way is to throw a book at it.

    I had always been told there were actually 5 parts to fire extinguishment and removal of any of them puts out the fire, heat, fuel, oxygen, chemical chain reaction, or the chief. Most often the chief is the most difficult element!

    But isn't the chief the guy throwing the book at it?

    Staffing of eight? OK but not one more than that! Otherwise you might as well have a truck dozer and an engine dozer with real staffing.

    Me say that if the truck dozer has a pump, the engine dozer isn't necessary according to Krap Pile Kid. At least I think that's what he's saying. It's hard to tell because all he does is ask questions. Never really says much of anything.

    In that case, all of our chiefs have herps. Notice no "e".
