I still remember seeing a safety video in a 4-H tractor safety course I took around 10 years old. I wasn't paying too close attention to the video about PTO safety and how never straddle or step over a running PTO UNTIL they said, "and that is his testicles on the tray next to his bed". Talk about straighten up and pay attention quickly!I got out of construction when I was 25. I was constantly injured and my knees/hips/neck/back still give me trouble 20 years later.
Edit: I’ll add that I saw a guy get his pants caught in a PTO and walk away with no injuries. I fell off of 3 sections of scaffolding onto concrete and walked away. I was shocked multiple times. I’m honestly quite lucky to be alive.
I don’t worry about seeing somebody’s legs get ripped off in my office.
