A Repeat violation means OSHA cited the employer for a substantially similar violation within the past 5 years. Penalties multiply (up to ~$165,000 per repeat citation) and indicate the employer failed to permanently abate a recurring hazard.

Reference
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
Each citation specifies a section of 29 CFR, a severity tier, and a proposed penalty. Employers can contest citations through OSHA’s informal conference or before the OSH Review Commission.
Open vs closed
An open case has not yet been administratively closed — citations may follow or the case may close without action.
Current vs initial penalty
Initial penalty is the proposed amount at citation. Current penalty is the post-conference / settlement figure on file today.
Trigger types
A = Accident, B = Complaint, H = Programmed, F = Follow-up. See the glossary for all codes.
