S-2.1, r. 4 - Safety Code for the construction industry

Full text
2.21.4. When planning and performing work, the employer must identify workplace situations that may exceed the noise exposure limits and implement reasonable means to eliminate or reduce noise, in particular by taking into consideration one or several of the following means:
(1)  eliminate or reduce noise at source;
(2)  limit the propagation of noise by enclosing a machine or piece of equipment;
(3)  reduce a worker’s exposure, in particular by isolating a workstation;
(4)  maintaining a machine or piece of equipment and keeping it in proper working order.
When it is not possible to respect the exposure limits, the employer must implement all the reasonable means identified, even if they do not allow the noise to be reduced sufficiently to respect the exposure limits.
