Designated Substance and Hazardous Materials Survey

The Ontario Occupational Health and Safety Act requires building owners to identify Designated Substances prior to any demolition or renovation work on their property.

A Designated Substances Survey (DSS) is an investigation to determine the presence or absence of Designated Substances or Hazardous Materials such as Asbestos, Lead Paint, or Mould.

Hallex Environmental ensures that your property’s DSS is handled in a safe and responsible manner.

DSS services include:

  • Indoor/outdoor air sampling; and
  • Testing of building materials (e.g. asbestos, lead)
