Occupational hygiene consists of assessing health and safety in the workplace by evaluating and controlling exposure to chemical, physical, ergonomic, and biological hazards.
Within Ontario, the Ministry of Labour under the Occupational Health and Safety Act is the governing body that regulates occupational exposures to workers who may be at risk. Under the Act, employers are responsible for taking all measures reasonably necessary under the circumstances to protect workers from exposure to a hazardous biological or chemical agent.
Our first step is to conduct an assessment of the hazards at a given worksite. An assessment typically consists of:
Examples of Hygiene Assessments can include evaluation of exposure to contaminants such as:
Monitoring Worker Exposure to Chemicals and Airborne Contamination
After the hazards have been identified and a plan has been drawn up, ongoing monitoring of workers is essential to ensure that the measures taken to limit or reduce exposure to contaminating substances are effective.
Typical monitoring may include:
Certain industries require specific and stringently controlled conditions for manufacturing – a pharmaceutical company being a good example. A ‘cleanroom’ is a closed environment where products are manufactured and the standards are often set by legislation.
Naturally, a cleanroom necessitates a higher level of vigilance than most others when it comes to monitoring environmental conditions. In particular, the concentration of airborne particles is most often a crucial parameter. Particle concentrations must be sampled and monitored on an ongoing basis to ensure optimal conditions and reduce the likelihood of any downtime due to contamination.
Maintaining such strict standards involves controlling all the variables, including:
Occupational Exposure Limits (OELs) for Ontario Workplaces Table 1 has been updated as of January 2013; it can be found here: Occupational Exposure Limits – Ontario
The table contains information found in the Ontario Table in Regulation 833 (“Regulation”) and the ACGIH Table that is referenced in the Regulation.
In addition, the table includes listings (i.e. Petroleum ether, Rubber solvent and VM&P Naphtha) not included in either the Ontario Table or the ACGIH Table. The Ministry recommends that OELs for those substances be calculated using the recommended method referenced.
