Hearing Conservation Amendment to the OSHA 200 log.

← All interpretations§ 1904

OSHA’s standing caveat

Interpretation letters explain existing requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. Enforcement guidance may be affected by later changes to OSHA rules, and a letter addresses the facts it was given — not necessarily yours.

June 26, 1992 Mr. James J. Hamulav Kimball & Curry, P.C. Suite 1600 2600 North Central Avenue Phoenix, Arizona 85004 Dear Mr. Hamula: I am responding to your letter dated February 18 which was transferred to my office from the Directorate of Compliance. My Division of Recordkeeping Requirements is responsible for administering the OSHA injury and illness recordkeeping system nationwide. Please excuse the lengthy delay in our response. The June 4 memorandum describes OSHA's interim policy of issuing citations for violations of 29 CFR Part 1904 when employers fail to record occupational hearing loss on the OSHA Log and Summary of Occupational Injuries and Illnesses (Form 200). Employers are still expected to comply with all of the provisions of the Hearing Conservation Amendment (29 CFR Part 1910.95). Many companies have been recording Standard Threshold Shifts (STS) of 10 dB or greater (as defined in the Hearing Conservation Amendment (HCA)) on their OSHA Logs. If these companies continue to do so, they will be in complete compliance with the injury and illness recordkeeping requirements and enforcement policy. OSHA does not want to discourage your client companies from continuing this practice. If they continue to record 10 dB shifts on their OSHA Form 200, they should revise the baselines using the HCA provisions to avoid recording the same STS more than once. If your clients choose to record 25 dB shifts on the OSHA Form 200, the initial shift must be measured from the employee's "original baseline". The "original baseline" is the baseline audiogram first established as a result of the RCA. This could be a 1983 audiogram under the RCA, a pre-1983 audiogram grandfathered in under the RCA, or a pre-employment audiogram given to an employee hired after 1983. When a 25 dB shift occurs and the case is recorded on the OSHA Log, that audiogram will then become the new reference baseline for future measurements. Another recordable case would not be logged until the employee suffers a 25 dB shift from the new reference baseline. I hope you find this information useful. If you have any further questions please contact my staff at (202) 523-1463. Sincerely, STEPHEN A. NEWELL Acting Director Office of Statistics
