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.
Serious633%
A Serious violation is one where there is substantial probability that death or serious physical harm could result, and the employer knew (or should have known) of the hazard. Maximum penalty is ~$16,550 per violation. The majority of OSHA citations fall into this category.

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.
About this inspection
OSHA classified this as Planned (Programmed) — a programmed (planned) inspection, typically targeting high-hazard industries.
