ECN Forum Forums General Topics of the Trade General Discussion Area RF Shielding

Can anyone comment on RF Shielding as it relates to MRI installation. I'm not concerned about what RF Shielding does. I need to know about where my responsibilities as the electrical contractor began, and end. I'm also concerned about the actual procedures of the installation. I'm looking at the possibility of bidding a few MRI installations in the future, and I need to know the "problems" that are unique to this type of installation. I'm familiar with the theory. I just need some practical advise on the installation procedure.

Yo Watt,
I KNEW you were gonna put in some new medical equipment, just in case ya gotta work on me!!

I was hoping someone with more recent experience would come up with an answer. You're likely only going to have to provide power for this thing, but if they really want you to include hook up in your contract, they better come up with a set of instructions and specs. When I was in business, if they did not come up with manufacturers info, I would exclude it from the contract.

I know these things are not hazardous, as with X-rays, but they do have their own set of eccentricities that would make me be very leery of it in my contract.

Watt, as I understand MRI's the shielding is embedded in the wall covering. A new unit was just installed in the hospital where I used to work and I thought the electric contractor just ran the 3-ph wiring to the switchgear. not too sure though.
