Air testing

Fusion Technical Ltd are fully qualified and can arrange to undertake air testing to cover all the client’s needs. Asbestos fibre air monitoring is used to detect the level of asbestos fibre within the atmosphere. There are various different applications and situations in which air monitoring should be undertaken.

Types of Air Tests Undertaken

Static sampling is appropriate for:

Personal sampling is used:

Scanning Electron Microscopy (SEM)

Scanning Electron Microscopy enables a magnification of up to 200,000x, with fibre counting at 2000x, as opposed to 500x magnification when using a Phase Contrast Optical Microscope (PCOM) method.

X-ray diffraction enables identification of the fibre type i.e. differentiates asbestos from other non-asbestos fibres.
Current government policy is to leave asbestos in situ and manage it through preventing disturbance to it. This approach is sensible and pragmatic for low risk, well-bounded materials, but does not adequately control the risk presented by higher risk materials such as asbestos insulation boards, lagging and sprayed coating.

There is an acute need to determine whether there are elevated asbestos fibre level concentrations in buildings and whether the occupants of buildings are being exposed to this risk.

Reassurance air monitoring by PCOM, commonly to a limit of detection of 0.01 f/cm3 is inadequate for detecting fibre asbestos concentrations experienced through normal occupation but remains the favoured pragmatic technique for detecting the higher concentrations produced when asbestos is disturbed.

Fusion Technical can arrange to undertake SEM air monitoring for our clients.
