When Is It Necessary

A DSS (Designated Substances Survey) is required prior to any construction job, from demolitions, to renovations or restorations. An inspection is considered mandatory in order to take the steps necessary for a safe and healthy working environment, preventing unsafe exposure from hazardous materials.

 

What a Designated Substances Survey Includes

A Designated Substances Survey is tailored according to the particular space being inspected. A typical DSS consists of:
— An extensive visual examination for all designated substances
— The collection of physical samples for further testing by third-party, accredited laboratories
— Air testing for lab analysis
— A detailed report that meets the requirements of the Ministry of Labour
