[AusNOG] [AUSNog] : Re Data Centre Fire Suppression Safety

[John Edwards]

FM200 residue is mostly all of the gunk and grease in the pipes left over from their manufacture and threaded-metal-fitting assembly.

People can operate comfortably below 15% oxygen.  In fact at 10% you can still function more than enough to pick up your gear and leave the room.

We're not used to thinking of this as a hazardous environment, but consequent totwo techs being found dead working on a fire suppression system in Antarctica, I find myself wondering yet again, why there aren't more stringent controls around the fire suppression systems in data centres: viz - when you enter a data centre, how confident can you be you're not going to be quietly asphyxiated?
