Asbestos Testing: How to Test for Asbestos
Asbestos testing is a very important aspect of running a workplace. Because it is a hazardous material, asbestos testing and removal is a delicate process where there is little room for error. While businesses outsource their testing to third party specialists, it is still important to understand how the testing process works regardless.
What is asbestos?
It is a substance consisting of naturally occurring minerals. Due to its particularly potent heat resistance, it was used as insulation for a wide range of building products throughout Australia for about half a century, including, but not limited to:
- flat and corrugated sheeting
- cement pipes
- floor tiles
- automobile parts such as brake pads
- textured paints
Because Australia was one of the highest users of asbestos per capita, we continue to find it in construction parts to this day. However, products containing it were phased out during the 1980s, with a national ban on products and importation coming into effect in 2003.
Laboratories conduct testing in order to ensure that this substance is not in a location where it can affect people and cause serious harm. This testing is enacted for both the home and the workplace.
Why is asbestos dangerous?
When workers handle asbestos-containing materials in an unsafe manner, fibres can be released into the air. These fibres can be 50 to 200 times thinner than a human hair, can be inhaled easily and can be near impossible to detect. When inhaled, these fibres become trapped deep in your lungs, which causes extensive damage over long periods of time.
The two asbestos-containing material groups include:
- Bonded (non-friable) materials, made up of a bonding agent (such as cement) with fibres added. They usually contain less than 15% of asbestos and normally do not release fibres unless they are disturbed, damaged or have deteriorated over time.
- Friable (loosely bound) materials are those which can be crumbled or reduced to powder by hand. Bonded asbestos can become friable if severely fire damaged or crusted. Friable asbestos materials are the most dangerous as the fibres can be released into the air.
This is why businesses need to ensure regular testing services in their workplace. The potential for employees or visitors to come into contact with this hazardous material is high enough that regular testing is important for keeping everyone safe.
How to test for asbestos
Testing is carried out in specialised scientific laboratories using methods such as:
- Polarised Light Microscopy Testing - A detection method in which a polarised light microscope observes details of a substance that would otherwise be invisible due to their optically anisotropic characteristics.
- Dispersion Staining Testing - An analytical technique used in light microscopy in which the differences in light refraction between a standard and unknown material are observed using a known dispersion curve.
Testing techniques such as these are complex, and cannot be performed without the necessary testing expertise and equipment. This is why businesses outsource their testing to expert institutions that know testing protocols.
How can I identify asbestos in my workplace?
Because asbestos is difficult to identify and you can’t tell if a material contains it with the naked eye, the testing requires specialised testing equipment. In order to confirm whether or not a material contains asbestos, you need to submit a sample of said material to a laboratory approved by the National Association of Testing Authorities (NATA) in Australia or International Accreditation New Zealand (IANZ) in New Zealand for testing services.
It is important to only have qualified personnel extract the material samples for testing. These qualified personnel include:
- Professional occupational hygienists
- Licensed removalists
- NATA & IANZ accredited laboratory staff
What areas in the workplace are likely to contain asbestos?
Some of the areas in the workplace where you may potentially find hazardous material that needs testing are:
