Designated Substances in Laboratories
Ontario Regulation 490/09 under the Occupational Health and Safety Act states that any work done with designated substances must be reviewed by an assessment program to determine whether a control program has to be put into place.
The designated substances are as follows:
Coke oven emissions
Mercury, including Mercury-containing Thermometers, Manometers, etc.
*Silica means crystalline silica in a respirable form. This does NOT include Silica Gel.
If you have any of the above listed substances in your lab in any quantity, please fill out the Designated Substance Assessment Form for each substance and return it to Sarah Lamb in Safety, Health, Environment & Risk Management (SHERM). SHERM will contact you to set up an assessment of the use of the designated substance and work with you to get the appropriate controls in place if necessary.
If you have already been through the review process for designated substances used in your lab, please submit a new form if significant changes are made to the handling and use of the substance.
Please contact Sarah Lamb at extension 3108 or by email at email@example.com if you have any questions about this program, or if a substance that is used or stored in your lab is included in the above list.
