Asbestos Information

The Electrical Safety Authority’s Health and Safety Requirement for Personnel to Enter a Facility that has confirmed or suspected asbestos containing materials (ACM).

Asbestos and Asbestos-Containing Material (ACM) – Your Responsibilities

Asbestos-containing material is a major safety risk for anyone working or living on-site.  If ESA suspects the presence of asbestos-containing material on your site – such as a home renovation or construction project – we are required by law to advise you of this concern.

We cannot proceed to complete the electrical inspection until the owner or contractor(s) provide information confirming the site has been tested for asbestos containing materials, in accordance with Ontario regulation 278, and that it will either not be disturbed, or that it will be properly removed. This is confirmed through providing a Designated Substance Survey (DSS), and a certificate that it has be removed by a competent person.

If that information cannot be provided then ESA requires confirmation that the air quality at this site meets occupational exposure limits.  This can be done through an air quality test.

Ontario Regulation 278/05 governs safety precautions that must be followed for all work on or around asbestos-containing material, or work that is likely to disturb asbestos-containing material. The Ministry of Labour has confirmed this Regulation applies to work performed by constructors, employers and workers at a private residence.


Designated Substance Surveys

The Regulation requires a Designated Substance Survey (DSS) to be completed prior to commencing any work. This survey samples materials on the site to determine if they contain asbestos. Any asbestos-containing material that will be disturbed or removed as part of work must be removed according to the Regulation. More information...


Air Quality Tests

If a Designated Substance Survey was not completed prior to commencing work an air quality test can be done to confirm that the air quality in the building meets occupational exposure limits. Air quality tests must be completed by a competent professional. (Certified Industrial Hygienist (CIH), a Registered Occupational Hygienist (ROH), a Registered Occupational Hygienist Technician (ROHT), Canadian Registered Safety Professional (CRSP), or Professional Engineer).  To find a qualified professional, refer to the links under “Additional Resources”. Submit your full report along with Asbestos Reporting Forms (HS-3015).


ESA Suspects Asbestos-Containing Material in my Residence / Building. What do I do?

ESA cannot proceed to complete the electrical inspection until the owner or contractor(s) provide information confirming that the site is safe to enter by providing either the Designated Substance Survey or the results of the Air Quality Test.  

In order to avoid delays due to an unsafe work site make sure you have the designated substance survey available upon request by the ESA inspector. 

If further information is required send any reports and supporting documentation meeting the outlined requirements to:
