OSHA definitely wasn't around then. Kind of even looks like an empty flask in hand, unless that was his water bottle. With the working conditions as they were, IIRC there weren't that many deaths, but then again, my memory may be shot

Those folks must have been truly desperate, fearless, or stupid. Maybe all 3.
