Fire Destroys Southampton Fibre-Optics Center

Sam Haine '95 writes "BBC News reports that a fire has burnt down a CS facility at the University of Southampton. It's notable because the facility was one of the best in the world." From the article: "Some of the most advanced research work in the country, and indeed the world was carried out in this facility ... We probably will have to start from scratch, and it will take a couple of years to rebuild the facility"

What about the building's fire sprinkler system? Why did it fail? Or why didn't it have one?

Sprinklers wouldn't have

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.
