Industrial Hygiene Worker Exposure Monitoring

Airzone offers exposure monitoring and analysis services to its clients. In Ontario, the Occupational Health and Safety Act (OHSA) and its Regulations are enforced by the Ministry of Labour. These laws are designed to help protect a worker in the workplace on a day-to-day basis over their career. Almost all facilities and workplaces across the province manufacture, produce, or use products that may expose a worker to a chemical or physical agent. Airzone can assist its clients with their responsibility to ensure a worker’s health and safety is maintained while performing their duties.

Ontario Regulation 833 is referenced when workers may be exposed to chemical or biological agents. Exposures to noise must comply with the limits set forth in Ontario Regulation 381/15 – Noise. Designated substances are a special group of compounds which may pose increased risk to a worker’s health. These are identified and regulated under Ontario Regulation 490. Regardless of the type of exposure, an employer must comply with the general duty clause which states that an employer shall take every precaution reasonable in the circumstances for the protection of a worker. An employer must be able to demonstrate that worker exposures to any substance listed in the regulations has not been exceeded over the worker’s 8-hour shift or 40-hour work week as well as any short-term or ceiling limits.

Worker exposure monitoring may be required for any number of reasons including:

  • Process or Production Changes
  • Ventilation Changes
  • Worker Complaints
  • Ministry of Labour Orders
  • Due Diligence
