NOISE & HEARING CONSERVATION
It is the policy of Tulane University
in conjunction with the Office of the Environmental Health and Safety (OEHS) to
provide employees with a safe and healthful work environment. The OSHA standard for Occupational Noise Exposure
(29 CFR 1910.95) requires employers to provide employees with protection
against the effects of noise exposure when sound levels exceed the Permissible
Exposure Limit of 90 dBA as an 8-hour Time Weighted Average (TWA). Protective measures may be provided either
through engineering or administrative controls.
If these control measures fail to reduce the noise to within acceptable
limits, personal protective equipment shall be provided and used. Participation in a Hearing Conservation
Program is required when employee noise exposures equal or exceed the “action
level” of 85 dBA as an 8-hour Time Weighted Average (TWA).
The goal of the Hearing Conservation Program is to protect employees from
noise-induced hearing loss due to excessive and/or prolonged workplace exposure
to hazardous noise (i.e., noise levels equal to or greater than 85 dBA). The program includes the following elements:
- Supervisors and/or departmental personnel are
responsible for notifying the OEHS of noise complaints or potential noise
hazards.* Upon request or as deemed appropriate, work
environments will be surveyed by the OEHS to identify potentially
hazardous noise levels and personnel at risk. Equipment, processes or locations where
noise levels equal or exceed 85 dBA should be posted with appropriate high
noise warning signage.
- Employees with workplace noise exposure levels
greater than or equal to an 8-hour Time Weighted Average (TWA) of 85 dBA
must participate in the Hearing Conservation Program.
- Personnel who participate in the Hearing Conservation
Program will receive initial and annual audiometric testing to monitor the
effectiveness of the program. These
personnel will be provided with hearing protective devices (earplugs or
ear muffs) and annual training.
Departmental supervisors are responsible for providing training to
all affected personnel however the OEHS can provide training materials and
other assistance.
- Whenever feasible, noise levels will be taken into
consideration when purchasing and selecting equipment as well as design or
remodeling of workplaces which may contain high noise sources.
* NOTE:
As a basic rule of thumb,
noise levels may equal or exceed 85 dBA if you need to raise your voice to be
heard by someone standing about 3 feet away from you.
