We had some interesting failures during 9/11 as well -- for some reason, the UPS didn't kick in, so everything went down - and then came back a few minutes later as the generators came online -- and then went down again ~2 hours later -- turns out that the genset air filters got clogged with dust, and suffocated the diesel. This was "fixed" a few days later by brushing them off with brooms and paintbrushes -- by this point they had completely discharged the 24V starter batteries, and so someone (not me!) had to lug a pair of car batteries and jumper cables. They restarted, and ran for a while, and then stopped again. It turns out that getting a permit to store lots of diesel on the roof is hard (fair enough), and so there was only a small holding tank on the roof, and the primary tanks were in the basement -- and the transfer pump from the basement to roof storage was not, as we had been told, on generator power.... We had specified that the transfer pump be on the generator feed, there was a schematic showing at is being on the generator feed, there was even a breaker with a cable marked "Transfer Pump (HP4,5)" --- but it turned out to just be a ~3ft piece of cable stuffed into a conduit, and not actually, you know, running all the way down to the basement and connected to the transfer pump.

This is like putting rabid weasels in your pants, and later expressing regret at having chosen those particular rabid weasels and that pair of pants. ---maf ---------------------------------------------------------------------- This message and any attachments are intended only for the use of the addressee and may contain information that is privileged and confidential.
