Hazardous Materials Surveys

Since the inception of the below listed Occupational Health & Safety (OHS) Regulation, it’s become common practice to ensure that sites are free of potentially hazardous materials prior to the demolition of a building or structure.

JMB Environmental Ltd has been providing professional and cost-effective hazardous materials surveys and reports since 1981. A typical hazardous materials survey will focus on the following materials:

  • Asbestos
  • CFC’s
  • Halons
  • Lead
  • Mercury
  • Mould
  • PCB’s
  • Silica
  • Other Site Specific Materials


Part 20.112 of the OHS Regulation

Before work begins on the demolition or salvage of machinery, equipment, buildings or structures, the employer or owner must:

  1. ensure that a qualified person inspects the site to identify any asbestos-containing materials, lead, or other heavy metal or toxic, flammable or explosive materials that may be handled, disturbed or removed,
  2. have the inspection results available at the worksite, including any drawings, plans or specifications, as appropriate, to show the locations of any hazardous substances,
  3. ensure that any hazardous materials found are safely contained or removed, and
  4. if hazardous materials are discovered during demolition work that were not identified in the inspection required by paragraph (a), ensure that all work ceases until such materials are contained or removed.
