Do I Need An Asbestos Test Conducted On My Building?
The EPA requires that an asbestos testing is conducted before you demolish or renovate a building to ensure that any asbestos containing materials are not disturbed and create a potentially toxic and harmful environment.
Additionally, it is recommended that older buildings regularly get asbestos testing as damage to older structures is more likely, and the usage of asbestos was more popular in the past. This means that older buildings are more likely to house asbestos materials that can become dangerous at any time.
What Is An Asbestos Air Test
There are two different types of asbestos air tests, a “Phase Contrast Microscopy (PCM)” and a “Transmission Electron Microscopy (TEM) “. TEM is generally regarded as the more accurate test as they can detect smaller fibers.
What Is A PCM Test?
PCM tests use a pump to pull an air sample through a filter. Then the filter is removed and examined through a microscope to see if there are any fibers visible on the filter. While the process is generally quick and inexpensive, it can miss smaller fibers. Additionally, PCM can’t accurately say whether a fiber is an asbestos fiber or another type of fiber, which means that identifying fibers is only step one, and then they would need to be tested.
What Is A TEM Air Test?
TEM air tests send air samples directly to a lab where they are testing with electrons. This process allows the tester to determine whether a fiber is an asbestos fiber or something else. It also gives the ability to detect smaller fibers that the human eye can miss.
What Test Do I Need?
With many asbestos testings we would generally recommend a PCM test prior due to its speed and cost efficiency. But, with larger scale projects and with higher end buildings that require an extra degree of confidence, a TEM test is recommended.
With that being said, we would highly recommend a TEM test to be performed at the end of an asbestos removal project to ensure that the job was completed properly. Contact us today to learn more about the asbestos testing process and to set up a time for a testing today!
