What is the typical content and display timing for an OSHA 300A posting?

• A. A detailed daily log of all incidents, posted year-round
• B. A summary of injuries and illnesses; posted February 1 through April 30; displayed conspicuously at the workplace
• C. A list of all chemical hazards in the facility
• D. A schedule of annual safety meetings

Answer: (B)

The key idea here is understanding what OSHA requires to be posted about injuries and illnesses. OSHA 300A is the annual summary of work-related injuries and illnesses for the previous year. It does not show detailed incident records or daily logs—that information lives in the OSHA 300 log and 301 incident forms. The 300A provides totals: how many injuries/illnesses occurred, how many resulted in days away from work or job transfer/restricted work, and how many were other recordable cases. It must be posted in a conspicuous place at the workplace from February 1 through April 30 so employees can review the overall safety picture for the prior year. If there were no incidents, the 300A still gets posted with zeros.
