About OSHA inspections
The U.S. Occupational Safety and Health Administration (OSHA) conducts inspections under several triggers: programmed targeting of high-hazard industries, employee complaints, workplace accidents, fatalities, and follow-ups to prior citations.
Citations

Open vs closed

Current vs initial penalty
Initial penalty is the proposed amount at citation. Current penalty is the post-conference / settlement figure on file today.
