DSS Asbestos & Hazardous Materials Management

DSS Asbestos & Hazardous Materials Management


Cambium's team specializes in environmental and health and safety and can help you assess and control exposure of workers and the public to hazardous materials in a building. We provide designated substance surveys (DSS), asbestos and hazardous material assessments and indoor air quality assessments.

Our team has a wide area of expertise and experience related to the management of hazardous materials. We are trained professionals and can conduct field surveys and tests to provide necessary information for contractors involved in on-site works or for compliance and due-diligence purposes. We are happy to help you meet your needs and requirements related to applicable standards and regulations for the purpose of due diligence.

We offer DSS, asbestos and hazardous materials management services that include the investigation and coordination of remediation related activities associated with the interior health and safety of a structure. Our services include:


Designated Substance Surveys and Hazardous Materials

Cambium consultants offer solutions to meet many requirements of the Ontario Occupational Health and Safety Act prepared by the Ministry of Labour. In particular, the requirement that all designated substances at a project site must be reported to all construction contractors working within the facility is regulated by Ontario Regulation 490 and Ontario Regulation 213. The purpose of a designated substance survey is to inventory the location of all designated substances within the facility.

A designated substance is defined as a biological, chemical or physical agent, or combination thereof, to which the exposure of a worker is prohibited, regulated, restricted, limited or controlled. Eleven (11) substances have been designated in Ontario: acrylonitrile, arsenic, asbestos, benzene, coke oven emissions, ethylene oxide, isocyanates, lead, mercury, silica and vinyl chloride; however, typically four (4) of the substances are commonly encountered in buildings such as the one on-site and include:

  • Asbestos (building materials).
  • Silica (concrete, masonry, stone and boiler refractory).
  • Mercury (thermometers, pressure gauges, and paints).
  • Lead (paint applications and pipe solder).

The objective of a designated substance survey is to identify and quantify the extent of designated substances located at the site through sampling and analysis. A typical designated substance survey includes the following:

  • Collection of building material samples that may potentially contain a designated substance (typically related to asbestos, lead and mercury).
  • Mapping, photographing records and documentation of all sample locations.
  • Report generation detailing the presence or absence of designated substances throughout the site.

The designated substance survey can also be incorporated into a Designated Substance and Hazardous Materials (DSHM) Survey which identifies any hazardous materials throughout the building such as PCB light ballasts and PCB containing window caulking.  A DSHM is particularly important for demolition projects where all materials must be disposed of under Ontario Regulation 347.

Cambium has dedicated, professional and experienced staff trained to conduct clear designated substance surveys used to provide required information to contractors involved in on-site works.  The prepared deliverables will ensure contractors take appropriate steps to control exposure of workers to all designated substances existing within the facility.


Asbestos Survey and Inspection

Asbestos-containing materials still exist in many buildings throughout Ontario and can present a significant degree of risk to workers and building occupants if disrupted through maintenance or renovation programs. Ontario Regulation 278/05 Designated Substance – Asbestos on Construction Projects and in Buildings and Repair Operations, requires the building owner to establish whether any handled building material contains asbestos and whether the asbestos is friable or non-friable.

Asbestos-containing material is defined as material that contains 0.5 percent or more of asbestos by dry weight. Friable asbestos is material that can be crumbled by hand pressure when dry. Prior to demolition or renovation, an asbestos survey must be completed by a competent worker to establish the amount and type of asbestos-containing material(s) in a building.

Cambium can assist clients in conforming to Ontario Regulation 278/05 by conducting an asbestos survey which includes the following:

  • Assessment of the facility, including visual verification of building systems, equipment and site components, interviews with building operations staff and review of any available drawings, reports and photos.
  • Collection of potential asbestos containing material samples in general accordance with Ontario Regulation 278/05 to be verified through laboratory analysis.
  • Documentation of the condition of all potentially asbestos-containing material substances.
  • Mapping, documentation and photographs, of all sample locations.
  • A report of all asbestos containing materials within the facility.
  • Annual updates to the report, as required by Ontario Regulation 278/05 as part of the on-going asbestos management of the building.

Flood Management Services

Cambium’s flood management services include assessment for water damage, sewage contamination, mould and other associated risks.  Our staff has the capability of developing remediation and potential infection control procedures (health care facilities), remediation monitoring, and necessary clearance for re-occupancy.
