LCS Laboratory offers a professional-grade Asbestos Fibres in Air Test Kit for homeowners, using Transmission Electron Microscopy (TEM). This cutting-edge method, developed by the National Institute of Occupational Safety and Health (NIOSH) and known as NIOSH 7402, is the preferred choice of asbestos abatement professionals for accurately identifying asbestos fibres, even in the presence of other fibrous materials like wood or glass. This test specifically measures asbestos fibres, ensuring compliance with the regulated limit of 0.01 fibres per cubic centimetre (ff/cc), thereby confirming the air is safe.

When to Use This Kit

Homeowners can use the NIOSH 7402 TEM test as a reliable self-assessment tool, particularly if asbestos has been unexpectedly disturbed during renovations. Because it isolates asbestos fibres from other airborne particles, this test is ideal when non-asbestos fibres are also present, providing specific, accurate results unaffected by non-asbestos fibres.

Kit Contents and Sampling Process

The Asbestos Fibre Test Kit includes:

  • An air sampling pump,
  • Multiple cassettes for collecting airborne asbestos fibres,
  • Sampling instructions (also downloadable from our “Sampling Manuals” page),
  • Prepaid laboratory analysis.

Once you’ve collected the samples, simply fill out the “Air Testing” request form and return it, along with the pump and samples, to our laboratory for analysis.

Best Time for Sampling

Perform this test only after asbestos removal is complete and the area is fully cleaned of dust and debris. Sampling during ongoing renovation or cleanup may overload the test with construction dust, which can affect results. The purpose of this clearance test is to confirm the area is safe for re-occupancy.

Understanding Your Laboratory Report

The laboratory report will be provided as a Certificate of Analysis. Under “Asbestos Concentration in Air,” you may see one of the following:

  • “<0.002” – Asbestos fibres are not detected. This is the ideal outcome.
  • “0.005 Chrysotile” – A low concentration of Chrysotile asbestos (0.005 ff/cc) is present. Although asbestos is detected, the level is below the regulated limit, indicating a low exposure risk.
  • “0.012 Amosite” – A high concentration of Amosite asbestos (0.012 ff/cc) is detected. This exceeds the permissible limit, indicating the room should be re-cleaned and retested for safety.
