Most employers are required to post the OSHA Form 300A from February 1 – April 30 every year. Employers that are classified with a low-hazard Standard Industrial Classification code or have 10 or fewer employees are exempt from posting.
If there were no recordable incidences in the previous year, the summary form must still be posted with zeros. The form should be posted in an area frequented by employees, usually close to the compliance postings.
