I wrote, and checked, procedures at my workplace, I love to write. I was an Electronic School grad (and a Opticianary School grad, and almost a Pharmacy Technician School grad - the job I made a career of, in the mill, offered the job one month before I completed the Pharmacy School), but the electrical things there at my employer I retired from were beyond my initial comprehension. 3000 HP motors that ran on 15,000 volts, and had Breakers the size of refrigerators. They were older breakers, newer ones are big, but not quite that big. All new experiences for me, I almost left the first day, everything was massive. I've included a photo of my workplace, the emissions are steam, probably particles lifted in it, but now it's river water used to quench coke, I didn't work at the river, or in coking, we recovered chemicals from the Coke Gas and Cooling Water. Years ago they got rid of contaminated water by quenching with it, it must have been horrible. Today they use clean water, though there are other emissions from the plant. Thought you might enjoy the photo. Thanks much for the thoughtful message. I'd seen it sooner, but an online friend is in Spain, since he can't leave home, he blogs all day, and my inbox is filled with notices. He doesn't speak English, I don't speak Spanish, we use Google Translate. LOL.
