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"
Halon systems generally give a certain amount of warning before going off. The server rooms where I work have Halon fire supression systems, and there are placards and lights/buzzers everywhere that tell you "you've got 60 seconds to exit the room once this light turns on." The same warnings are found in fireworks stores, and I would presume factories.
It's not like suddenly the oxygen in the room disappears and everyone asphyxiates. Halons are basically a super-powerful CFC. They destroy ozone (hence removing oxygen from the air, which sucks if you rely on oxygen, like humans).
There are alternatives to halons, as discussed here: http://www.harc.org/harcnews.html.
Just a correction on the news item: the actual CS department was unharmed, and CS students are unlikely to be directly affected at all. According to an interview with the admin Chris Gutteridge on Surge FM (Coral) (the Uni radio), all students files and documents are safe and were backed up. The internal intranet and internet connectivity is still up, although a couple of servers have been cut off. It is electronics students and researchers who have lost out here.
For those that aren't aware, Soton has a combined electronics and computer science facility. Electronics in Mountbatten, and CS in the attached Zepler building. Only Mountbatten was affected, and Zepler recieved only minor smoke and heat damage. This is remarkable as Mountbatten has been entirely gutted due to the explosions, whereas Zepler appears to be otherwise perfectly fine.
Mountbatten did have a modern sprinkler system, quite why it failed and why the fire escalated will be investigate in the next few days. There are also concerns over the lack of information about chemicals stored there, which prevented fire crews from stopping the fire earlier.
Also, the reason why halon was discontinued is not related to people getting trapped and dying (if I understood correctly, halon should be efficient at very low concentrations). The problem was that it damages the ozone layer. (taken from the same page: "By international agreement, however, production of all types of halons ceased in 1994 because the bromine and chlorine atoms in the chemical were found to migrate over time to the stratosphere, where they react to deplete ozone in a very efficient catalytic cycle.")
