Slightly off topic: I once owned a construction company. We built concrete foundations. One day an OSHA representative shows up to the site. My foreman asked the representative if the excavation met OSHA standards. (if the banks of an excavation are not shelved properly, a cave off could injure or kill a construction worker). My guy thought they were OK, but he wanted to make sure. The OSHA guy wouldn’t tell him. He more or less said that we would find out after we put men into the hole whether or not we would get a citation. My guy pulled the crew off the site. Government regulation for you.
I’m not sure I would want to cross a man who digs holes and then fills them up with concrete for a living. To many places to dispose of unwanted things, like OSHA inspectors.
Once had an OSHA Affirmative Action hire tell us that our guys need to be wearing life vests and have a boat on site since they were working near a drainage ditch that had water flowing in it 5 inches deep.
Couldn’t find it in her book, but she was sure it was in there
In the mining industry, I have seen the same thing from MSHA inspectors. If you try to get a specific answer to a question such as how high a worker has to be from the ground before fall protection is required (to mention but one), you cannot. They will write citations if they feel like it.
