Funniest example i saw was a former groundsman tried to be an arborisrt...he put on his high vis vest, put out all his cones, put his ear plugs and safety glasses on, then climbed and stood on the verry top of a ladder that had clear markings 4 rungs from the top, reached out with the chainsaw and started cutting the branch he was hanging on to....i think you can guess what happened......
So as im realizimg whats unfolding in front of me and unable to get his attention , he realizes at the last moment part of his stupidity.... He is then left dangling by one hand, one foot on the ladder and a running chainsaw hanging from him....
All the procedures, policies and ppe wont stop morons inventing new ways to hurt themselves...
The same guy got electocuted twice and had to be severely repremanded for doing wheelstands on a full size tractor, mowing up an unsafe embankment...using only the slasher to stop the tractor flipping....
