New CNESST standard on silica

Silica, present in many building materials such as concrete, mortar and tiles, is a substance potentially harmful to human health when inhaled in the form of dust. Workers exposed to high levels of silica are at increased risk of developing serious respiratory diseases, including silicosis

The Commission des normes, de l'équité, de la santé et de la sécurité du travail (CNESST) recently introduced a new standard to protect the health of workers exposed to silica on construction sites in Quebec. This standard aims to reduce silica exposure levels and prevent associated respiratory illnesses.

The new CNESST standard imposes several obligations on employers, including :
- Regularly measure silica exposure levels on worksites.
- Implement engineering controls to reduce silica dust emissions.
- Provide adequate training to workers on the risks associated with silica and the preventive measures to be taken.
- Set up medical surveillance programs for exposed workers.

Employers are required to comply strictly with the new CNESST standard. This means investing in appropriate personal protective equipment, implementing dust control measures on worksites, and providing ongoing training for workers.

The implementation of the new CNESST standard will have a significant impact on the construction industry in Quebec. Companies will have to adjust their work practices and safety policies to comply with the new regulations, which could lead to additional costs and operational challenges.

CNESST's new silica standard represents an important step towards protecting the health of workers in Quebec's construction industry. By implementing dust control measures and providing adequate training, employers can help reduce the risks of exposure to silica and preserve the health and well-being of their workers.
