[c-nsp] Multiple power supply failures. Advise needed

Well, I find the idea with whiskers particularly interesting, because a lot of things 
described are perfectly matched with my situation.
We did recently moved, the data-center does have tiled raised floor (don't know if it zinced though)
and the airflow is bottom to top which probably helps to bring conductive particles like metal dust 
up to the server level where it can be sucked by the power supply fan.
The place is new and we've been the first to occupy it, so we have the longest 
exposure and if this theory is true we should be the most affected and we are.

Now I've spent last hour googling and I can't see what I can do to help it.
Any suggestions?

Michael
