Act respecting occupational health and safety

(chapter S-2.1, s. 223).

CHAPTER I INTERPRETATION AND SCOPE

1. In this Regulation,

“asbestos” means the fibrous form of mineral silicates belonging to rock-forming minerals of the serpentine group, that is, chrysotile, and of the amphibole group, that is, actinolite, amosite, anthophyllite, crocidolite, tremolite, or any mixture containing one or more of those minerals;

“mine” means any establishment, with or without a processing or transformation mill, at which exploration, other than the boring of an artesian well, or extraction from the ground or from bedrock is done for the purpose of removing a mineral substance to obtain a commercial or industrial product;

Buildings, warehouses, garages and workshops located on the surface and in which work related to exploration or extraction of a mineral substance is performed are part of a mine.

A mine includes a quarry or a sand pit, but not a peat bog;

“physician in charge of health services” means the physician in charge of health services in an establishment, as referred to in Division III of Chapter VIII of the Act respecting occupational health and safety (chapter S-2.1);

“silica” means cristobalite, quartz, tridymite, fused silica or any mixture containing one or more of those minerals.

O.C. 1325-95, s. 1.

2. The purpose of this Regulation is to ensure the medical monitoring of workers who perform work in a mine where they are exposed to asbestos or silica, in order to prevent and screen for pulmonary diseases caused by those contaminants.

This Regulation does not apply to a worker governed by the Act respecting labour relations, vocational training and workforce management in the construction industry (chapter R-20).

This Regulation does not apply to a worker does only office work on the site of a mine. Notwithstanding the foregoing, this Regulation, except sections 3, 4, 6, 7 and 8, applies to such a worker if he holds a pulmonary health certificate or has previously held a pulmonary health certificate or a medical certificate within the meaning of the Regulation respecting the medical certificate of workmen (R.R.Q., 1981, c. S-2.1, r. 3).

This Regulation applies to a worker who, on 2 November 1995, does not hold a medical certificate but is in the employ of an employer who operates a mine within the meaning of section 1. Subject to sections 13 to 15, such worker is deemed to hold a pulmonary health certificate.

O.C. 1325-95, s. 2.

CHAPTER II GENERAL PROVISIONS

3. An employer shall not hire a worker for the purpose of having him perform work referred to in section 2 unless the worker, in accordance with this Regulation, has undergone a pre-employment pulmonary health examination and holds a pulmonary health certificate.

Notwithstanding the foregoing, a worker who holds a valid pulmonary health certificate when hired is dispensed from that examination.

O.C. 1325-95, s. 3.

4. An employer shall not have a worker do work referred to in section 2 unless the worker, in accordance with this Regulation, has undergone the pulmonary health examinations during employment and holds a pulmonary health certificate.

Notwithstanding the foregoing, for a period of not more than one year, the employer may have such work done by a worker who, for a valid reason such as a layoff, was unable to undergo a new pulmonary health examination. The employer and the worker shall then take the necessary steps for the worker to undergo the examination as soon as possible.

O.C. 1325-95, s. 4.

5. Notwithstanding sections 3 and 4, an employer may hire a worker who does not hold a pulmonary health certificate and has a pulmonary occupational disease, for the purpose of having him perform work referred to in section 2, or may have such work performed by such worker during employment, if a decision rendered pursuant to the Act respecting industrial accidents and occupational diseases (chapter A-3.001) states that the worker is capable of performing work that exposes him to asbestos or to silica, despite functional limitations or an intolerance to either of those contaminants.
