Actinolite, Anthophyllite & Tremolite Asbestos Testing to International Standards: Australian FirstPosted 10th February 2021, Carl Strautins
Safe Environments: first laboratory in Australia to obtain NATA accreditation in identifying actinolite asbestos, anthophyllite asbestos, and tremolite asbestos to the international standards for asbestos identification ISO 22262-1 Air quality — Bulk materials — Part 1: Sampling and qualitative determination of asbestos in commercial bulk materials.
Accreditation status for asbestos testing is significant as the model Work Health and Safety ( WHS ) Regulations at clause 423 requires that ) If a person with management or control of a workplace arranges for an analysis, the person must ensure that the sample is analysed only by:
- a NATA-accredited laboratory accredited for the relevant test method
- a laboratory approved by the regulator in accordance with guidelines published by Safe Work Australia; or
- a laboratory operated by the regulator.
Subsequently, by having asbestos testing conducted by Safe Environments you can be assured that you comply with the WHS regulations when identifying actinolite asbestos, anthophyllite asbestos, and tremolite asbestos. You also don’t need to have samples sent to a third party as we have capabilities in X-ray diffraction (XRD) and scanning electron microscopy (SEM)
In many cases asbestos laboratories may find fibres that are not chrysotile, amosite or crocidolite and they must then report as unknown mineral fibres. This is because they are not accredited for the testing of actinolite asbestos, anthophyllite asbestos, and tremolite asbestos
When unknown mineral fibres are identified then many labs then send samples for asbestos testing to third parties that are not accredited by NATA for the confirmatory techniques such as x-ray diffraction (XRD) or scanning electron microscopy (SEM). For instance, some asbestos testing laboratories where unknown mineral fibres are detected XRD has been known to be used to detect serpentine. Whilst chrysotile asbestos is a serpentine, there is a risk is for false positive results
Safe Environments are now accredited by NATA for identification of asbestos using polarised light microscope (PM) for actinolite, anthophyllite and tremolite asbestos as standard practice. Stay tuned as Safe Environments have satisfied requirements as part of a recent NATA audit to add actinolite asbestos, anthophyllite asbestos, and tremolite asbestos using XRD and scanning electron microscopy (SEM).
