When to Record

As you learn of work-related incidents (injuries or onsets of illness), work with the site manager to record information within seven (7) calendar days in Columns A-F and M of the form.

How to Record

How to Correct an Error

If you make an error, strike through the error and initial the strikethrough.  Do not use white-out or correction tape.

Retention and Updates

NKY Health must retain the OSHA 300 form, the privacy case list, the Annual Summary (OSHA 300-A), and the OSHA 301 Incident Report for five (5) years following the end of the calendar year.  

The OSHA 300 forms must be updated over the five (5) year period to include any newly discovered recordable injuries or illnesses and to show any changes that have occurred in the classification of previously recorded injuries and illnesses.  If the description or outcome of a case changes, NKY Health must remove or line out the original entry and enter the new information.  

Updating the OSHA 300-A (Annual Summary) and the OSHA 301 Incident Report is voluntary (there is no requirement to update these two documents).
