Dear Mr. Burdman:

Thank you for your letter dated January 7, requesting clarification on the proper recording of hearing loss cases on the OSHA 200 log. You letter was forwarded to the OSHA Office of Statistics by the New York Regional Office. The Division of Recordkeeping Requirements is responsible for the maintenance of the injury and illness recordkeeping system nationwide.

As explained in the enclosed June 4, 1991 memorandum, for federal enforcement purposes, a company will be cited for not recording a work related cumulative shift in hearing of 25 dB or greater. A company that records a Standard Threshold Shift (STS) (defined as 10 dB or higher) would be in complete compliance with the injury and illness recordkeeping requirements. If a worker is exposed to noise levels in excess of an 85 dB 8-hour time-weighted average, as found in the hearing conservation standard, any hearing loss is presumed to be work related.

When entering recordable occupational illnesses on the OSHA Log, the date of initial diagnosis or recognition of the illness is used. The date of the audiogram which reveals the recordable shift in hearing should be used to satisfy this criteria (e.g., if a 1990 audiogram shows a recordable shift in hearing, the case should be entered on the 1990 OSHA Log). If the employee's hearing loss resulted from an instantaneous event or exposure and is evaluated as an injury, enter the actual date of the work incident which resulted in the injury (see section A on page 9 of the enclosed Recordkeeping Guidelines for Occupational Injuries and Illnesses).

If a recordable injury or illness is discovered within 5 years after an employee retires (i.e., the maintenance and retention period of the records), the case should be recorded in the year of occurrence if the date of injury or onset of illness can be identified. If not, the case should be recorded in the retiree's last year of employment (see Q&A E-5 on page 23 of the Guidelines).

When a case involves an employee who has had multiple employers, the employer responsible for administering the audiogram which revealed a recordable shift in hearing must enter the case into the company's OSHA records. This holds true if workplace exposure contributed to any part of the loss of hearing. The entire shift in hearing need not be attributable to that specific company to be considered a recordable case.

I hope you find this information useful. If you have any further questions, please contact us at Area Code: (202) 219-6463.
