A. Engineering controls should be instituted to reduce noise levels to reasonable limits where practical. In all areas where noise hazards exist, warning signs should be posted at entrances or on the periphery of those areas. B. Hearing protection must be worn when the noise level exposure equals or exceeds 90 dBA for eight hours. The department in which the noise hazard is located will provide the hearing protection. The type of hearing protection is left to the needs of the worker and the department with consultation from the Department of Public Safety and the Speech and Hearing Center.
Employees are responsible for wearing the prescribed hearing protection.
