I have been doing research into the wiring of dialysis treatment centers and it appears to be a hazardous environment to me but the inspector checked with the insurance commission for the state and they said that it is not.
I believe that it might be because it (acetic acid) has corroded mc cable and emt in the crawl space and walls.
17 - pieces of mc cable, and 18 - pieces of 3/4" emt have to be either replaced or the acetic acid has to be removed from them.
[I think that some of the mc cable and emt has to be coated with DTR which is an epoxy that will protect them from corrosion. The raceways that have to be cleaned will be scraped off with a wire brush. We will have to wear respirators, coveralls, and gloves.]
I am not absolutely sure that I will solve this problem in the manner that I just explained because the paint store that advised me on the treatment method did so before learning that we were dealing with acetic acid. I need to learn the proper safety procedures for working in this type of environment.
There is not pvc coated mc cable on the market rated for patient care areas, so the inspector does not see why I cannot coat the cable myself with something like DTR (which is dangerous itself).
I find it amazing that Dialysis treatment centers are not classified as hazardous environments. This center with all of its' leaky pipes must be an exception.
I will keep you posted as this project proceeds. If you have any suggestions they would be greatly appreciated.
