Report to Regional Health and Safety Officer

[SOR/2002-208, s. 11]

 Where it is not reasonably practicable, without providing hearing protectors, for an employer to maintain the exposure to sound of an employee to whom section 7.4 applies at a level that does not exceed the limits prescribed by that section, the employer shall, without delay,

  • (a) make a report in writing to the regional health and safety officer setting out the reasons why it is not reasonably practicable to do so; and

  • (b) provide a copy of the report to the work place committee or the health and safety representative.

Hearing Protection

  •  (1) Where an employer is required to make a report pursuant to section 7.6, the employer shall, as soon as is reasonably practicable, provide every employee whose exposure to sound is likely to exceed the limits prescribed by section 7.4 with a hearing protector that

    • (a) meets the requirements set out in CSA Standard Z94.2-M1984, Hearing Protectors, as amended from time to time; and

    • (b) prevents the employee using the hearing protector from being exposed to a level of sound that exceeds the limits prescribed by section 7.4.

  • (2) Where an employer provides a hearing protector to an employee pursuant to subsection (1), the employer shall

    • (a) in consultation with the work place committee or the health and safety representative, formulate a program to train the employee in the fit, care and use of the hearing protector; and

    • (b) implement the program.

  • (3) Every employer shall ensure that every person, other than an employee, to whom the employer grants access to a work place where the person is likely to be exposed to a level of sound that exceeds the limits set out in section 7.4 uses a hearing protector that meets the standard referred to in paragraph (1)(a).

  • SOR/91-448, s. 1;

Warning Signs

  •  (1) At every work place where an employee may be exposed to an A-weighted sound pressure level greater than 87 dBA, the employer shall, at conspicuous locations within the work place, post and keep posted signs warning of a potentially hazardous level of sound in the work place.

  • (2) For the purposes of subsection (1), the measurement of the A-weighted sound pressure level in a work place shall be performed instantaneously, during normal working conditions, using the slow response setting of a sound level meter.

  • SOR/91-448, s. 1;
  • SOR/98-589, s. 7.
