Asbestos survey, called also asbestos location survey or, asbestos assessment survey or, asbestos testing and inspection is required by Ontario Regulation 278/05 Asbestos on Construction Projects and in Buildings and Repair Operations for all buildings in which friable or non-friable building materials are present. Friable asbestos-containing materials (ACM) include those that can be crumbled and pulverized by hand pressure. Non-friable ACM are those that require tools to be broken and pulverized. Friable ACM most often found in buildings include: mechanical systems thermal insulation, fireproofing, soundproofing and other acoustic applications. Non-friable ACM include: drywall joint compounds, plasters, vinyl asbestos flooring materials, acoustic tiles, gaskets, putties, and caulks.

An asbestos survey is required to establish whether the materials present in the building contain asbestos and to delineate the location and condition of asbestos-containing materials (ACM).

An asbestos survey is based on a walk-through inspection and sampling of suspect building materials for asbestos.

An assessment of relative risk of exposure to airborne asbestos takes place during the survey. Factors included in the assessment include:

Type and amount of asbestos in ACM,
Friability and condition of ACM,
Accessibility to building occupants,
The likelihood of disturbance by regular activities in
the building.

The assessment of relative risk of exposure constitutes basis for recommendation of corrective action if such is deemed necessary. An Asbestos Survey Record constitutes part of an Asbestos Management Program which is required for all buildings where friable or non-friable ACM is present. A more extensive survey including intrusive inspections and encompassing all designated substances is necessary prior to a re-construction
or demolition work.
