Sampling of contaminants in workplaces

Sampling of contaminants in workplaces

Contaminants in workplaces specific to each industry

Our professionals establish sampling plans of the contaminants present in various work environments, for:

  • Dust: crystalline silica, wood dust, metal dust, respirable dust, etc.
  • Welding/cutting gases and fumes.
  • Chemical compounds: Formaldehyde, benzene, volatile organic compounds (VOCs).
  • Micro-organisms: Moulds, yeast, bacteria, and endotoxins.
  • Gas and biogas: Carbon monoxide, carbon dioxide, nitrogen dioxide, sulfur dioxide, methane, etc.

Noise exposure assessment

Noise exposure assessment

Excessive noise levels: From discomfort to hearing loss

Our team of professionals can support you in:

  • The development of a periodic sound levels verification program.
  • The assessment of workers noise exposure using continuous measurements (dosimetry).
  • Carrying out a complete mapping of the factory or the workplace to determine the critical areas.
  • The issuance of an expert report with results interpretation and appropriate recommendations.

Respiratory protection program

Respiratory protection program

A respiratory protection program according to current standards

Our professionals support our clients in the various stages of their respiratory protection program.

  • Analyzing the contaminants present in the building to know the respiratory protection required, either by process analysis, on-site inspection or by sampling.
  • Support in setting up the respiratory protection program.
  • Fit tests
  • Training workers on the exposure risks specific to their industry and on the respiratory protection required.

Compliance of breathable compressed air

Compliance of breathable compressed air

All employers must ensure the compliance of the breathable compressed air supplied to workers

Our team of professionals takes samples according to the appropriate CSA standard for the required breathing air supply systems, every 6 months.

We can also carry out analysis in a certified laboratory for the specific analysis of gases, volatile hydrocarbons (other than methane), halogenated hydrocarbons, oils, particulate matter and condensates.

In addition, our experts carry out compliance checks, in particular in accordance with the CSAZ180.1-00 standard – article 48 of the Regulation respecting occupational health and safety (RSST).
