It has been posted here several times over the years.
I used to do Maintenance work on multi stage evaporator`s in the food processing industry, 100' was the limit for me.
By the time I left there, we could not work more than Ten feet off the ground with out a full harness.
I can remember setting some 30,000 gallon tanks in the early days when we used to ride the ball on the hook up....... I better not finish that story.
