February 1 marks the deadline for covered employers to post a new summary of work-related injuries and illnesses.

The summary—the U.S. Occupational Safety and Health Administration’s (OSHA) Form 300A—is required to be posted in the workplace every year from February 1 to April 30. The summary form must be completed and posted even if no work-related injuries or illnesses occurred during the year.

Employers with 10 or more employees whose workplaces aren’t classified as a partially exempt industry must record work-related injuries and illnesses using OSHA Forms 300, 300A, and 301. (Partially exempt industries include those in specific low-hazard retail, service, finance, insurance, or real estate industries.) Information on which employers are required to keep them and links to the forms are available on OSHA’s website.
