· NOISE CONTROL AND
HEARING CONSERVATION PROGRAM
The employer must ensure that a worker’s
noise exposure does not exceed 85 dBA over an 8-hour time period. (Occupational Health and Safety Code, 218)
NOISE CONTROL AND HEARING
CONSERVATION PROGRAM
The employer must ensure
that all reasonably practicable measures are used to reduce the noise to which
workers are exposed.
The employer must ensure
that a new work site, significant alterations to a work area, new work process
or new equipment are designed or constructed such that the continuous noise
generated is not more than 85 dBA or as low as reasonably practicable.
(Occupational Health and
Safety Code, 216-7)
If workers may be exposed to noise in excess of 85 dBA over an 8-hour
period, the employer must conduct a noise exposure assessment in accordance
with CSA Z107.56-94 (R1999) Procedures for the Measurement of Occupational
Noise Exposure.
Noise exposure must be measured using a type 2 sound level meter
meeting the requirements of ANSI S1.43-1997 Specifications for
Integrating-Averaging Sound Level Meters, a type 2 noise dosimeter meeting
the requirements of ANSI S1.25-1991 Specifications for Personal Noise
Dosimeters, or an integrating sound level meter meeting the requirements of
ANSI S1.43-1997 Integrating-Averaging Sound level Meters.
The employer must ensure that a noise exposure assessment is conducted
by a competent person and updated if a change in equipment or process affects
the noise level.
(Occupational
Health and Safety Code, 219)
If a noise exposure assessment confirms that workers are exposed to
excess noise, the employer must develop and implement a noise management
program that includes policies and procedures.
The noise management program must include a plan to educate workers in
the hazards of exposure to excess noise and train workers in the correct use of
control measures, methods and procedures to be used when measuring worker
exposure, posting of warning signs in work areas where the noise level exceeds
85 dBA, methods of noise control to be used, selection, use and maintenance of
hearing protection, requirements for audiometric testing and an annual review
of the program.
(Occupational
Health and Safety Code, 221)
The employer must ensure that hearing protection provided meets the
requirements of CSA Z94.2-02 Hearing Protection Devices – Performance,
Selection, Care and Use.
The employer must provide workers with training in the selection, use
and maintenance of hearing protection in accordance with manufacturer’s
specifications, and ensure that workers wear the hearing protection.
Workers must wear the hearing protection provided in accordance with
training.
(Occupational
Health and Safety Code, 220)
The employer must provide an initial baseline test as soon as
practicable after a worker has been exposed to excess noise, but not later than
6 months after the worker is employed, and at least every second year. (Occupational Health and Safety Code, 223)
