29 CFR 1910.95(g)(8)(ii)(C): Unless a physician determines that the standard threshold shift is not work-related or aggravated by occupational noise exposure, the employer did not ensure, when a standard threshold shift occurs, the employee was referred for a clinical audiological evaluation or an otological examination, as appropriate, if additional testing is necessary or if the employer suspects that a medical pathology of the ear is caused or aggravated by wearing of hearing protectors: a) Polishing department The employer did not refer an employee with a standard threshold shift for otiological examination. Two employees in polishing were exposed to continuous noise at 140.8% and 175.7% of the permissible exposure limit (PEL) eight hour time-weighted average sound level of 90 dBA which are 1.41 and 1.76 times the allowable exposure limit. The equivalent sound levels of the measured doses are 92.5 dBA and 94.0 dBA, respectively. Sampling was performed for 484 minutes and 482 minutes on 6/9/16. The dosimeter threshold level was set at 90 dBA. Violation occurred on or about 6/3/16. b) Test firing department The employer did not refer an employee with a standard threshold shift for otiological examination. Two employees in test firing were exposed to continuous noise at 289.0% and 309.7% of the permissible exposure limit (PEL) eight hour time-weighted average sound level of 90 dBA which are 2.89 and 3.10 times the allowable exposure limit. The equivalent sound levels of the measured doses are 97.6 dBA and 98.1 dBA, respectively. Sampling was performed for 443 minutes and 485 minutes on 6/9/16, with the un-sampled portion of time considered to represent zero exposure for the exposure calculation. The dosimeter threshold level was set at 90 dBA. Violation occurred on or about 6/3/16.
