I am pretty sure OSHA can only enforce regulations if you have employees. If you are a one man operation and the sole proprietor of the business, OSHA regulations do not apply, or at least they cannot make you comply. I had an OHSA inspector come to my home, listed as my business address, and asked where were the FED Labor posters, wanted to see my company safety and training manuals etc. At the time I had no employees and told him I was a one man operation. He made a notation in his book, left without me showing him anything, and never came back.
