EHS 110: Hearing Conservation Program
To protect employees from noise exposures; to conserve hearing ability; and to prevent occupational hearing loss
29 Code of Federal Regulations §1910.95
Arizona State University Hearing Conservation Program
Employees who are exposed to noise greater than 85 decibels on the A scale (dBA) and/or employees who work in areas where excessive noise levels, or the potential for excessive noise levels, may exist
ASU provides hearing protection to employees, when needed, to prevent occupational exposure to noise levels that exceed or may exceed permissible exposure limits established by the U.S. Occupational Health and Safety Administration. Administrative and/or engineering control measures, e.g., enclosures, damping with absorbants, sound insulating, job rotation, etc., must be considered and implemented, when feasible, prior to the use of hearing protection. If administrative and/or engineering controls are not feasible, appropriate hearing protection must be used.
An employee whose job function requires the use of hearing protection must receive an initial audiogram examination and training before his or her initial assignment, and annually thereafter.
ASU maintains a Hearing Conservation Program (HCP) for university employees who may be exposed to excessive noise levels during the performance of their duties. The HCP is designed to achieve regulatory compliance and to provide a means for employees to be better informed about and protected from excessive noise levels and hearing loss.
Environmental Health & Safety develops, implements, and maintains the university’s HCP and written plan, assists departments with evaluating hearing hazards, and provides guidance on suitable control measures, including appropriate protective equipment. In addition, Environmental Health & Safety reassesses work areas as necessary and provides employee training.
Environmental Health & Safety performs an evaluation of the noise levels in suspected work areas. When measurement results indicate that any employee’s noise exposure may equal or exceed an 8-hour time-weighted average (TWA) of 85 dBA, monitoring is conducted to document the exposure and determine whether the employee should be included in the HCP. Screening and additional monitoring is repeated whenever a change in production, process, equipment, or controls increases the noise exposures. Employees who are exposed at or above an 8-hour TWA of 85 dBA are notified of the results in writing.
Departments and units must identify employees who may be exposed to excessive noise levels and ensure that these employees are provided the protections required by the HCP. In addition, departments must determine whether administrative and/or engineering controls can be used in lieu of hearing-protective equipment and implement these controls when feasible; establish and maintain written standard operating procedures; ensure that only properly trained and medically evaluated employees use hearing-protective equipment; and document and maintain all records pertaining to employee audiometric examinations and training.
Department supervisors are responsible for identifying potentially harmful noise levels in their work areas. Supervisors may suspect potentially harmful noise levels when noise in the work area routinely interferes with verbal communication; when noise routinely startles, annoys, or disrupts an employee or interferes with his or her ability to concentrate; or when it is the suspected cause of noticeable hearing loss or pain. Whenever a harmful noise level is suspected, the supervisor must notify Environmental Health & Safety.
All employees who are exposed to a TWA of 85 dBA or greater must receive an initial audiogram examination by a qualified physician, otolaryngologist, audiologist, or certified technician. This examination consists of a baseline audiogram and annual audiograms thereafter.
Before using hearing protection, each employee who is exposed to noise levels at or above an 8-hour TWA of 85 dBA must receive training upon initial work assignment to areas that are identified as excessively noisy, and annually thereafter or upon request. Information provided in the annual training program is updated to be consistent with any changes in protection devices and work processes.
The training includes, but is not limited to, the following topics:
Employees who work in noisy areas during the performance of their duties must use safe work practices, wear appropriate hearing protection while performing job functions, attend training on noise and hearing protection, report changes in workplace or “noisy” conditions to their supervisors, and comply with all provisions of the HCP.
