3 Stages of Asbestos Air Monitoring

3 Stages of Asbestos Air Monitoring

Asbestos air monitoring is essential to detect the concentration of airborne asbestos at a site. The monitoring involves measuring the volume of air drawn through a membrane filter. The filter is subsequently put on a microscope slide to find out the presence of tiny asbestos fibres.

In this article, we will briefly explain the three important stages of asbestos air monitoring.

Stage 1 — Background Monitoring

The first stage of the asbestos air monitoring is carrying out a preliminary inspection of the site. Background monitoring is carried out to find out the exact area where the asbestos is located. During this stage, the asbestos removal experts try to determine where the problem exists prior to disturbance of the asbestos containing materials.

Asbestos fibres are counted using a technique known as Phase Contrast Optical Microscopy (PCOM). The concentration of asbestos in the air can be counted using this technique that should be carried out in accordance with Control of Asbestos Regulations 2012 (CAR 2012).

Stage 2 — Leak Monitoring

The second stage of the asbestos air monitoring involves finding out sources of asbestos fibre leaks. The tests that are carried out to detect leaks indicate where the asbestos fibres are spreading. A leak monitoring can help confirm the tests carried out during the background monitoring test. It can also inform asbestos removal experts about the presence of an asbestos hazard that was not revealed during the leak monitoring stage.

Stage 3 — Reassurance Monitoring

Reassurance monitoring is the third test of asbestos air monitoring. The test is carried out after the asbestos removal process is completed. The air monitoring test is carried out to ensure that the asbestos hazard has been completely eliminated from the area.

The reassurance test is also carried out in case a previously identified asbestos containing material has been damaged during repair works. In addition, it is carried out in case a non-licensed asbestos removal company had previously carried out disposal of asbestos but it is still suspected that the threat is not removed.
