In the early 2000's back when Dayton Tire was going they had a habit of hiring nonelectricians from Guatamala to do electrical work LIVE because they didn't want to shut down any work. One didn't make it out of the plant alive.Sand Springs fire dept. back in the early 70's, when I first started, ran on two guys that were electrocuted, Not a pretty site. They were working on the flat f roof of the box factory, carrying an aluminum ladder, and accidentally stuck the ladder into the main power supply for this factory! One survived and one didn't!!
