Occupational Exposure Limits (OELs) restrict the amount and duration of worker exposure to hazardous workplace substances such as asbestos, benzene and lead.
Consultation on the annual revised limits recommended by the American Conference of Governmental Industrial Hygienists (ACGIH) is the foundation of the Ministry of Labour (MOL)’s OEL update process. Through this process, the MOL has successfully updated OELs for over 200 hazardous substances since 2004.
The table posted on the MOL’s website contains new or revised OELs or listings proposed for 9 substances resulting from changes recommended in 2012 by the ACGIH. Stakeholders wanting to learn about the ACGIH, their “Notice of Intended Changes (NIC)” and opportunities to comment can visit www.acgih.org/TLV/NIC.htm
Important changes proposed based on the 2012 recommendations of the ACGIH include the following:
In addition to the changes noted above, the MOL is also proposing to withdraw the listings for certain substances listed in the Ontario Table in Regulation 833 that were previously withdrawn by the ACGIH on the basis that there was not sufficient data to support the determination of a separate OEL. Exposures to these substances will continue to be regulated by the OELs for Particles (Insoluble or Poorly Soluble) Not Otherwise Specified (PNOS).
Where an OEL for a hazardous substance has not been recommended and is not under consideration by the ACGIH at this time, stakeholders are invited during this consultation period to nominate the substance for development of an OEL. The submission should include a proposed limit and supporting documentation.
Stakeholder input is an essential part of the OEL updating process. Stakeholders are invited to submit comments on any or all of the proposed changes. Specific concerns should contain a clear description of the rationale and supporting documentation.
The 60 day consultation period ends March 11, 2013. Submissions may be mailed, faxed, or sent electronically to the following addresses:
