OSHA Form 300A is the annual summary of work-related injuries and illnesses that covered employers must complete, certify, and post in the workplace from February 1 through April 30 of the year following the reporting year. It must be posted even in a year with no recordable cases.
Form 300A summarizes the case-by-case detail recorded on the OSHA Form 300 log. It reports total cases by outcome, including deaths, cases with days away from work, cases with job transfer or restriction, and other recordable cases, plus total days away and days restricted, injury and illness types, and the establishment's annual average number of employees and total hours worked. Those denominators are what allow incidence rates to be calculated and compared.
A company executive must certify that the summary is accurate, and the certification cannot be delegated to a safety coordinator alone. The form is posted, as OSHA's recordkeeping rule requires, in a conspicuous place where employee notices are usually posted, at each establishment, and must be posted even if there were zero recordable cases for the year. Records are kept for five years.
Two details cause most of the mistakes. First, the exemptions are narrow: employers with 10 or fewer employees at all times during the prior year and establishments in certain low-hazard industries are partially exempt from routine recordkeeping, but all employers must still report severe events like fatalities and hospitalizations directly to OSHA. Second, posting is not the same as electronic submission. Many establishments must also submit 300A data electronically through OSHA's Injury Tracking Application by March 2, and larger establishments in designated industries must submit the 300 and 301 detail as well.
A company executive. The certification attests that the summary is accurate and cannot be delegated to a safety coordinator alone. In practice that means an owner, an officer, the highest-ranking company official at the establishment, or that person's immediate supervisor signs before the summary is posted.
Yes. The summary is posted at each establishment where employee notices normally appear even when the totals are zero. Skipping the posting because there were no recordable cases is a straightforward citation, and the records themselves are retained for five years.
No. Posting is a workplace notice requirement, while electronic submission is separate and applies to covered establishments based on size and industry. Employers subject to both obligations have to complete each one, and severe events such as fatalities and hospitalizations are reported directly regardless.
