 The agency has 840 compliance officers to handle all work sites in the country, between 7 and 9 million of them, Ketchum says. Jordan Barab, the former OSHA official, says it's a matter of resources. It would take 190 years for OSHA to inspect every workplace just once. So the likelihood of any employer seeing an OSHA inspector, unless one of their workers dies or there's a serious incident, is very low.
