Designated Substance Survey (DSS)


The Occupational Health and Safety Act (OSHA), ONTARIO REGULATION 490/09 DESIGNATED SUBSTANCES (O. Reg. 490/09), allows for certain toxic substances to be especially designated.  This means that specific regulations have been constructed for the control of these substances in the workplace.  There are eleven (11) designated substances deemed to be toxic and of particular concern.  These eleven (11) designated substances are:


1. Acrylonitrile  O. Reg. 8352. Arsenic O. Reg. 8363. Asbestos O. Reg. 2784. Benzene O. Reg. 8395. Coke Oven Emissions O. Reg. 8406. Ethylene Oxide O. Reg. 8417. Isocyanates O. Reg. 8428. Lead O. Reg. 8439. Mercury O. Reg. 84410. Silica O. Reg. 84511. Vinyl Chloride  O. Reg. 846


Accordingly, each Designated Substance Regulation outlines the amount of the substance that a worker can be exposed to (Classification of Work, i.e. Type 1 Asbestos Operations), ways to control the substance, personal protective equipment required and other safety measures, and ways to measure the substance in a workplace.


Section 30 of the OHSA deals with the presence of designated substances on construction projects.  Since silica, asbestos, lead, benzene and mercury are designated substances (O. Reg. 490/09), compliance with OHSA and its Regulations requires the owner of a project to determine if silica, asbestos, mercury, benzene and/or lead is present on a project through a designated substance survey and, if it is, to so inform all potential contractors as part of the bidding process.  In a similar way, contractors who receive this information are to pass it onto other contractors and subcontractors who are bidding for work on the project.  If the owner or any contractor fails to comply with this requirement, whey will be liable of any loss or damages that result from a contractor subsequently discovering that silica, asbestos, mercury, benzene and/or lead is present [clause 25(2)(d)].


A Designated Substance Survey includes a visual inspection (walk-through) of the site, to identify the readily-accessible areas for the presence of designated substances used in building and construction materials and equipment.  Accordingly, we assess the type, characteristics and condition of the building materials and when necessary samples of certain materials will be collected for subsequent laboratory analysis.


The result is a Designated Substance Survey Report that outlines materials of concern on the job site, lab analysis and results of materials tested, overall discussion of the materials (types, locations) found in the job site and conclusions/recommendations made according to these observations and testing.  


ERAM Consulting Designated Substance Surveys will also include inspections for other Hazardous Materials.  Depending on the Scope of the Project, the site and the building itself, this may or may not be necessary.  Other Hazardous Materials include:


1. Mold (Mould)

2. Polychlorinated Biphenyls (PCBs)

3. Ozone-Depleting Substances (ODSs)

4. Radon

5. Urea Formaldehyde Foam Insulation (UFFI)


These substances usually require special consideration due to legislation and waste disposal requirements.  Thus, in properly identifying these other Hazardous Materials on a project work site, work procedures and proper waste handling guidelines can be determined to minimize possible health and environmental impact.
