    But halon gas fire suppression systems should have - at least, to the degree of it not getting totally out of control. Without oxygen, fires don't generally do a whole lot - halon largely works by displacing all of the oxygen, leaving the fire nothing to work with.


    There's also the question of cannisters exploding... Cannisters generally don't do this - they tend to be rather boring, not even speaking much, unless there's something already happening. Cannisters will react to heat - but, like I said, a halon system should have dealt with heat sources long before they became a threat. Cannisters with explosive gasses CAN explode if the valve is leaky and there is a static discharge. But anyone leaving highly explosive substances around massive sources of static, or indeed, in containers that are faulty - well, they should expect something like this. You should generally store cannisters and gas cylinders in well-ventillated but secure locations containing no combustible materials or materials likely to pick up a static charge.


    In practice, you can't go around stowing every single piece of equiptment in absolutely ideal conditions. In consequence, accidents like this are going to happen. Because they are going to happen, the important thing is to keep the impact to a minimum. A lot of effort over the years has gone, not only in building fire suppressing systems, but also in figuring out how to build structures that will contain a fire. The slower a fire can spread, the more likely it is to exhaust fuel and/or oxygen before it can find more.


    Now, explosions get more problematic. Once you get explosions, there's not a whole lot even the best design can do, because you have to assume that there will be a sizable area affected. Aside from minimizing risk (through correct handling and operating procedurea) and trapping precursors (such as nearby fires, static, etc), there's not much that can be done. If you want to have a building survive explosions, you've got to design it very differently - lots of honeycombed structures that can absorb the high energies involved, for example. On the whole, though, you wouldn't design a fibre optics centre that way. Fibre isn't known for exploding. Fireworks factories SHOULD be built that way, and a lot of people killed in such explosions might well be alive if such buildings WERE built correctly for the conditions, but that's a whole different ball-game.

Indeed, bromine and chlorine atoms are released as halons decompose in the heat of the fire, establishing a catalytic cycle involving HBr and HCl; the cycle converts active hydrogen atoms to stable H2 molecules, breaking the chain reaction."

    Wood is one of the better materials to have in a fire. Yes it burns, but it has the rare characteristic that it gives warning before it fails. A steel floor feels perfectly stable underfoot while the firefighters are rushing around, and then suddenly reaches the fail point and falls. A wood floor starts feeling softer and softer underfoot until it suddenly fails. Fire fighters can estimate how much time they have left before the building goes by feel. (though odds are this building did not have wood floors)

    Wood is a good insulator, while steel conducts. A wood door will resist fire longer than a solid steel door, which will start whatever is on the other side of the door on fire. (steel fire doors have insulation inside that is better than solid steel, so this is a non-factor, but it is important to consider)

    Paper covered drywall is a great thing to have in a fire. 5/8inch drywall is good for 1 hour in a typical home fire. Multi-unit dwellings have drywall between all units for this reason.

    While smoke is always harmful, the smoke from a wood fire is much less harmfull than most other things that burn.

    Wood desks do not burn easily. The heat tends to spread too fast to catch the rest of the desk on fire. If the building is on fire the wood desks will make it worse, but if you start a wood desk on fire in the middle of a room (where nothing else will burn) it is unlikely to spread to the next desk.
