The warehouse I worked in doesn't sounds that different. I worked the night shift, so had the joy of working in temperatures of 100F because the tar roof would radiate heat all night and there was minimal ventilation. Dust gets everywhere so you have a nice coating of sweat and dirt after a shift. Once time the warehouse was flood, but product needed to go out, so it was 100F and 90% humidity.
Still a better job than the alternatives I had!
