How do you accidentally shoot a nail into you? Every nail gun I’ve ever used has a safety catch that has to be depressed before the gun will shoot.
On a nail gun, as also on a firearm, the safety is YOUR FINGER. Mechanical devices can fail. Safety is YOU, and following rules 1 through 3 of the Four Rules of Gun Safety.
“Every nail gun I’ve ever used has a safety catch”
My climbing partner was a carpenter and went west to climb in The Valley, also took a job framing.
The job frightened him!
He said all the nail guns had the had the safety removed or jammed up for bump nailing.
You get used to moving holding the trigger down.
Yes, you still need to pull the trigger, but if you brush the nose it fires with the trigger pulled.
OSHA came by the job, checked the extension cords never looked at the nail guns.
Lol, perhaps these days, but not in 1973 when I was worked on a house framing crew. There was certainly no “safety” on those nail guns. I got so comfortable with the nail guns that I would swing the gun up by the hose and grab hold of it. One time, as I tried to get hold of the gun, I guess I hit the trigger as I swung up the gun. The gun fired a nail into my upper thigh muscle. I didn’t feel a thing, but when I looked down, I saw the nail sticking out of my leg. I think only about an inch of so of the nail went in. I just reached down and pulled it out. The weird thing was, it never hurt and it never even bled after I pulled it out. I guess it went in and came out very cleanly.
