We always had to review accidents , industrial, and found the great majority were caused by not following safety rules and not using safety gear !
One company I worked for wanted things CLEAN. It resulted in better quality work , fewer accidents an even more pride in their work.I know of one steel company where dirt collecting on a beam prevented seeing a worsening crack , the beam then broke !.
WWII brought another problem many workers had no experience with machinery. Veronica Lake was one of many actresses who were used in posters showing dangerous situations .I remember one where she was operating a drill press and her long hair was caught and twisted around the drill bit !! Today we have style to deal with - long chains, rings ,floppy clothes - all dangerous !
We saw from minor cuts to death all easily avoided .
