seen it happen elsewhere and if you get in there and clean it all out fast enough it shouldn't be a problem, especially when you factor in the cost of the equipment you are talking about; besides if that was the case ie: writting equipent off if there is an activation of the fire suppression system, then why install it at all??? let it burn, end result is the same - equipement written off anyways and your not up for the cost to install an expensive fire suppression system
was old 737's there emergency foam canon switch was in very close proximity to the 3 phase switch, poor guy thought he was turning the power cart on
(he found a fault with the system though, only 2 of the 4 canons activated)
