Employers are required to post the OSHA 300A summary from February to April of each year to maintain OSHA recordkeeping compliance. This is an essential responsibility for employers – but can also be a confusing one.

Here are the 9 most common employer mistakes regarding the 300A posting:

Failure to post when there are zero incidents

Employers are required to post the Form 300A Summary even if there were no recordable injuries and illnesses. If there are no incidents, simply enter zeroes for the column totals.

Not posting the right data at the right time

When posting the 300A, be sure to post last year’s data. For example, the summary totals for cases that occurred in 2021 should be posted from February 1, 2022, to April 30, 2022.

Data doesn’t add up

If the number of cases does not equal the total injury and illness type, the OSHA 300 log may have been completed incorrectly.

Posting the OSHA 300A only on the company intranet

A paper copy of the Form 300A must be posted in a “conspicuous” place where notices to employees are customarily posted. Sharing only online is not sufficient to comply with OSHA guidelines.

No Signature

Everything on the form may be correct, but the form must be certified and signed by a company executive to comply with OSHA regulations. Make sure not to forget this important step!

Signed by the wrong person

The OSHA 300A Summary must be signed by a company executive. The Safety Manager or Human Resources Generalist normally does not qualify as a company executive.

Posting one OSHA 300A that covers multiple establishments

Employers must prepare an OSHA 300A for each establishment (location). An establishment is a single physical location where business is conducted, services performed, and operations housed.

Posting the wrong form

Employers must post the 300A Summary to comply with OSHA regulations. The OSHA 300 log should not be posted as it contains confidential information such as the injured employee’s name, the type of injury, the number of lost or restricted workdays, etc.

Confusing the OSHA 300A posting and electronic submission

Many employers are now required to also submit OSHA 300A data electronically to OSHA directly. This does not eliminate the need for these employers to post the 300A in paper format.
