Samples are taken from your home or office from likely Asbestos Containing Material (ACM) areas. Examples of common testing areas would be: walls, ceilings, floors, and rooves. The size of the sample is generally the size of a $.50 piece (which is roughly 2" x 2") in order to provide enough material for our lab to test with.
Who can take a sample? Well, there is a regulation called the Asbestos Hazard Emergency Response Act (AHERA) that the federal government enacted in the 1986.
Per this set of regulations, if a person who is not AHERA certified takes their own samples, this causes a new set of issues.
A homeowner can technically take their own samples, if they plan on renovating their house themselves, in a DIY fashion.
Other than that, a homeowner or business owner, cannot take their own samples. The results report that we would generate for those samples would not be valid for anything other than information. A contractor engaged in a demolition or renovation cannot use an asbestos results report where the samples were not taken by an AHERA certfied building inspector. This means that no work could happen on the home or business until new samples were taken and tested by our lab.
Our in house lab uses Polarized Light Microscopy (PLM) for our asbestos testing. This requires the use of 2 different kinds of scopes.
The first (picture on the right) is our Stereo Scope. This is used for looking at the bulk samples to see if there are any fibers in the bulk samples.
Fibers that are found are then reviewed with the PLM scope (the scope on the left).
The PLM scope allows the lab technician to analyze the sample at a much higher magnification. This polarized light will determine if the fibers seen with the stereo scope are indeed asbestos.
Once we receive the bulk sample described above, it is then prepared on the Stereo Scope. This allows the lab tech to decide whether or not further examination is needed with the PLM scope.
If the sample does require a more in depth review with the higher magnification PLM scope, then a slide is prepared with a mixture of liquid and small piece of the bulk sample.
What the lab tech is looking for, and a reason that polarized light is required for asbestos, is that the asbestos shows up as a specific color (depending on the type of asbestos). If there is any asbestos in the sample.
The small picture shown on the right is an example of a bulk sample testing positive for asbestos. The blue coloring in the picture is an asbestos fiber.
Once the testing is complete, then our lab tech submits a report which details any asbestos found sample by sample.
