Air sampling is used to detect and measure the level of asbestos fibres present. For some types of asbestos removal work, air sampling is mandatory but it can also be used to assess personal exposure, background levels and to provide reassurance following minor works. Whether a single background air sample or large complex areas such as boiler houses within a hospital, we have the experience, skills and knowledge to provide a competent service.

Air monitoring will be carried out in compliance with the HSE’s Guidance Note HSG248 Asbestos: The analysts’ guide as we are a UKAS accredited Testing Laboratory No. 4234 ensuring conformity to ISO/IEC17025:2005.

Air Monitoring can be offered on an emergency basis, available 24 hours a day 365 days a year. Read below for details of different types of test that can be provided or contact us for a consultation, where we will recommend a suitable strategy.

The type of air sampling will vary during repair or removal projects and a hierarchy of tests will be needed. We work closely with our clients to ensure that asbestos projects are effectively planned to provide quantitative evidence and reassurance to both occupants and visitors alike.

The ASP team of analysts hold the internationally recognised BOHS proficiency module P403 “Asbestos Fibre Counting” and the P404 “Air Sampling of Asbestos and MMMF and requirements for a Certificate of Reoccupation Following Clearance of Asbestos”. Importantly, each analyst has a minimum of 5 years experience undertaking asbestos air sampling and are multi-disciplined so can draw upon a wealth of knowledge to ensure the air sampling strategies adopted, are accurate.Read below to find out more about air sampling and for details of different types of air monitoring that can be provided or contact us for a consultation, where we will recommend a suitable strategy.


The Method

Air sampling involves drawing a measured volume of air, through a filter using a small pump. The filter is mounted onto a microscope slide for examination. The fibres are counted using phase contrast optical microscopy (PCM) and the concentration of fibres is calculated using the World Health Organisation (WHO) method.
