OSHA places special importance on posting and recordkeeping. The compliance officer will inspect required records of deaths, injuries, and illnesses. The officer will also check to see that a copy of the OSHA 300A Summary has been posted and that the OSHA poster is prominently displayed in a conspicuous place where employees can see it. The latest OSHA poster is OSHA 3165-02R 2026, but earlier years or earlier versions like OSHA 2203 are compliant. OSHA requires that reproductions or facsimiles of the federal OSHA poster be at least 8.5 by 14 inches with at least 10 point type. The caption or heading on the poster must be in large type, generally not less than 36 point. Be aware that state-plan states may require a state version of the OSHA poster.

An OSHA letter of interpretation dated June 15, 2023, explains that OSHA posters and other labor law posters may not be hung “on top of one another” on a wall-mounted hanger. Covering required OSHA notices with other documents, regardless of the nature of those documents, and requiring workers to manually locate OSHA notices does not meet the requirement nor the intent of 29 CFR 1903.2.

Where records of employee exposure to toxic substances and harmful physical agents have been required, they are also examined for compliance with the recordkeeping requirements. The officer may also ask to look at required inspection and training records and written programs, as well as the PPE hazard assessment.
