Hot you say? Nothing, when I was in engineering school in the early 60 s, my buddy was from a steel mill town in Illinois and would spend the summer at home earning some school money in the mill. One day he was asked if he wanted to work OT this coming Saturday in the Soaking Pit and remember to bring his steel tipped work boots. Report to gate 1234 and see the Forman. The Forman pointed him to a field shack and tolled him to pickup a hood, jacket, pants and wooden clogs to fit over his boots. BTW his out fit was all asbestos. Once at the pit, no water. The pit was about 50 feet deep lined with refectory brick, just about glowing. The pit is used to cool down the hot rolled steel slowly. The job is to go down into the pit and chip away the slag. there were 3 teams, each teem spent 3 minutes down, and came up when the whistle was blown, than the next teem went down, 3 down, 6 up. now he was a big, big boy, standing 6-7 at 260. When he got home he fell into bed, slept all night, did not get out of bed till late Sunday evening and still pooped Monday and Tuesday. Now can you top that for hot?
