Asbestos Bulk Sample Analysis

Asbestos was used in more than 3,000 different types of building materials from the 1950s to 1990s.  If your home was built before the 1990s and you are planning to do renovation(s), it is important to determine if any of the building materials contain asbestos.  When asbestos-containing materials are disturbed, asbestos fibres are released into the air.  The release of asbestos fibres into the air is a health risk for workers working on the property and the people living in the home.

Bulk sample analysis of potential asbestos-containing building materials needs to be conducted by a staff of highly trained and experienced laboratory analysts.  Astech's current roster of asbestos laboratory analysts has a combined experience of 20 years in locating and identifying the differing asbestiform minerals present in older fibrated building materials.

Astech's laboratory utilizes analytical method NIOSH 9002 Issue 2 'Asbestos (bulk) by Polarized Light Microscopy (PLM)' which is an accepted method of asbestos bulk sample analysis by WCB.


Astech participates in the American Industrial Hygiene Association (AIHA) Bulk Asbestos Proficiency Analytical Testing (BAPAT) Program as one method to ensure that proper quality control methods are in place.

How to Take Asbestos Samples

Follow these helpful instructions to collect samples for asbestos testing and analysis:

  • Spray the building material with a mixture of soap and water to prevent fibre from being released during sample collection.
  • While using a HEPA-filtered respirator, take a representative sample from within the materials suspected of containing asbestos by penetrating the entire depth of the material.
  • Place the sample in a sealable freezer bag and attach a label with material description and location.
  • For multiple samples, please enclose each sample in separate sealed bags. This avoids cross-contamination.


If you have any questions about sampling procedures or quantities, please call our office.
