I worked in a dealer shop that was an old bus depot. It was built like a Quonset hut with almost no ventilation. I measured 130 degrees in there near the sun exposed wall, so miserable with the exhaust of the cars running in there. If that wasn't bad enough, they had an engine steam cleaner in there which ran on kerosene, or diesel #1. When that thing was running it made my eyes burn and even stung my sinuses. Someone reported it to OSHA, or somebody, and they made them stop using it. My boss thought it was me but it wasn't. He insisted it was harmless, but he was never in there while it was running,
The best thing to happen to that building was the 1994 earthquake which caused part of it to collapse and it was condemned. They moved me into one of the surviving buildings. I went from having 5 stalls to 1 stall but I was right by the door and got even more ventilation from a hole in the wall courtesy of the earthquake.
