![]() (5) The employer shall notify each employee exposed at or above the action level of the results of the monitoring. (4) The employer shall provide affected employees or their representatives with an opportunity to observe any measurements of employee noise exposure which are conducted pursuant to this section. (B) The attenuation provided by hearing protectors being used by employees may be rendered inadequate to meet the requirements of Section 5098(b). (A) Additional employees may be exposed at or above the action level or (3) Monitoring shall be repeated whenever a change in production, process, equipment or controls increases noise exposures to the extent that: (D) Instruments used to measure employee noise exposure shall be calibrated to ensure measurement accuracy. (C) All continuous, intermittent and impulsive sound levels from 80 dB to 130 dB shall be integrated into the computation. (B) Where circumstances such as high worker mobility, significant variations in sound level, or a significant component of impulse noise make area monitoring generally inappropriate, the employer shall use representative personal sampling to comply with the monitoring requirements of this section unless the employer can show that area sampling produces equivalent results. (A) The sampling strategy shall be designed to identify employees for inclusion in the hearing conservation program and to enable the proper selection of hearing protectors. (2) The monitoring requirement shall be met by either area monitoring or personal monitoring that is representative of the employee's exposure. Such determinations shall be made by December 1, 1982. ![]() (1) When information indicates that any employee's exposure may equal or exceed an 8-hour time-weighted average of 85 decibels, the employer shall obtain measurements for employees who may be exposed at or above that level. For purposes of the hearing conservation program, employee noise exposures shall be computed in accordance with Appendix A and Table A-1 and without regard to any attenuation provided by the use of personal protective equipment. ![]() The employer shall administer a continuing, effective hearing conservation program, as described in this section, whenever employee noise exposures equal or exceed an 8-hour time-weighted average sound level (TWA) of 85 decibels measured on the A-scale (slow response) or, equivalently, a dose of fifty percent.
