MRI

2009-02-04 Thread Todd Williams
Where can I find some information regarding protection of an MRI space? Most of the installations have seen or designed are pre-action systems. I am now looking at one with a regular wet system with a valve and dielectric coupling. Are there any issues with water-filled pipe? Todd G.

Chris, You need to look at this just like any other storage occupancy. It can also depend on where you are. An Evidence Room in Los Angeles could be very different than one in East Wazoo. Is this for current cases or archival storage? Shelves? Racks? How high? If your storage is less than 12
