I disagree with Jerry…
I guess we al need to back up our facts.
In commercial/industrial use these are very common and designed so that the breaker can not inadvertently be turned to the off position by damaging equipment or leaving safety equipment useless.
They do not stop the breaker from acting to its design of tripping internally.
They by OSHA standards CAN NOT be used as a safety device for personnel protection for the mere reason that anyone can remove them with a screw driver. This particular breaker lock is designed to hold a switch in the on position or possibly in the off position but not for use with personal safety.
There are more specific safety switch protection for working on a breaker that OSHA recognizes. They must be key operated and the kept or keys must be held by the individual working on the circuit. This is all referenced in OSHA books. I don't have the exact reference material with me while I'm traveling but I would be happy to get it for you.
I was a safety inspector and had taken OSHA's courses to learn these facts. I also at one time thought that they were acceptable for lock out tag out safety. OSHA corrected me on that. In addition when lock out tag out is in effect it must be accompanied by a tag explaining the date and individuals name and time he or she is working on the item. (there are a number of sub categories to this as well
