UNCLASSIFIED We had this done last week. No problems at all.
In our situation, one of the compressors had some bad rings on it and needed to be replaced. The smoke alarms were isolated and they performed the welding work. This work was done in the plant room, and so not close to any computers, but the air handlers were still on and the smell came into the server room. While the smell wasn't that bad, the computers did not notice it. Once the work was finished (it lasted about 2 hours), the smell dissipated after about 36 hours or so. While I wasn't worried about the welding (well, I was a little), I was more worried about the fire system being isolated and people being in there, if we have another fire.

Hi everyone -- I have a middling-sized server room (~ 1500 square feet), which has an elevator room (much smaller -- 200 sq feet or so) off to one side. This elevator room is about 15 feet from the nearest equipment (server rack and UPS). I've just received notice that later this week, the smoke alarms will be turned off for five days: as part of a building upgrade, there's going to be a lot of welding to be done in this elevator room. My first reaction is to worry about the effect of smoke/welding fumes on our equipment. (I'll be asking them separately about access to the room during this time.) However, I don't know if that's overreacting -- I know smoke damage from a big fire would be a Bad Thing(tm), but maybe this is just trivial. Or perhaps this sort of thing requires additional ventilation for worker safety, and that will eliminate our risk. Some details: We have in-row cooling in our racks, but not much ventilation to/from the outside. The elevator room is normally locked, and I don't think it has any ventilation to speak of. Does anyone have any similar experience to relate? Alternately, how concerned would you be, and how hard would you push against this work, or to get additional safeguards in place? Thanks, and please let me know if you have any questions. -- Hugh Brown http://saintaardvarkthecarpeted.com Because the plural of Anecdote is Myth.
