For Ontario employers, we will help ensure that you comply with Ontario Regulation 490/09 (Designated Substances), which requires an assessment to determine whether workers’ health may be affected by exposure to a designated substance like lead, silica, mercury, isocyanates and asbestos.  If the assessment finds that workers’ health may be affected, a control program is required to protect workers.


ECOH can help ensure you are compliant with the regulation by evaluating whether lead and other designated substances are present in your workplace.  If there is likely to be exposure to designated substances or other hazardous materials, we can help you ensure that workers and building occupants are protected. 

Our services include:

  • Developing and updating designated substance surveys and data bases
  • Inspections, air monitoring and sampling during  and after abatement/ remediation work
