When I was working at the MCI training facility in 1994, I went into the power
facility classroom where they had battery strings, rectifiers, transfer
switches, etc for students to learn on. I noticed that every 8-10 feet there
was an 8 foot long 3/4 inch PVC pipe with about 16 feet of rope threaded
through it. When I asked what those were for, the instructor said “We will use
those to pull people off the electricity in case anyone gets shocked.”
I never heard that they were used, so that’s good.
