Question: If an employee experienced a recordable hearing loss case, where would the employer record the case on the OSHA 300 Log?

Answer: Prior to 2004, employers should record work-related hearing loss cases according to the instructions included with the Recordkeeping Forms. If the loss is associated with an event, such as acoustic trauma (e.g., an explosion), it would be recorded as an injury with a check mark in column (M)(1). If the loss is not an injury, it would be recorded as an illness, with a check mark in the all other illness column. Beginning in January 2004, employers must record all hearing loss cases in the separate hearing loss column (M)(5).
