69.11. Verification: Before undertaking work liable to generate dust by a direct or indirect action on or inside a building or any civil engineering works under the employer’s authority, the employer must check for the presence of asbestos in the materials and products likely to contain some.
Depending on the availability of information, the employer must also check for the presence of asbestos when purchasing those materials or products.
The employer may be exempted from the obligation imposed by the first paragraph if the employer shows that the work to be carried out is not liable to produce asbestos dust emissions.
