We offer a wide range of asbestos air monitoring services according to the environment.

We hold UKAS accreditation for asbestos air monitoring, air sampling and fibre counting (2075), and we are regular participants in the RICE inter-laboratory counting exchange.

Asbestos Fibres

  • Asbestos minerals incorporated in building materials break down to very fine fibres when disturbed
  • These fibres can linger in the air for a considerable time. The fibres are so small that they penetrate very deep into the respiratory system; hence, they are referred to as respirable fibres.
  • Whilst other materials may generate respirable size fibres to some extent, this phenomenon is a particular characteristic of the asbestos minerals.
  • The Control of Asbestos Regulations 2012 define a control limit and an air clearance limit for asbestos (respirable) fibres in air. These are regulatory fibre concentrations that must not be exceeded in specified situations.
  • Airborne respirable fibre concentrations are determined by collecting airborne dust on cellulose nitrate filters and counting the fibres under phase contrast microscopy.

Reassurrance Testing

  • Reassurance asbestos air testing provides information on respirable fibre concentrations in air, and helps to define whether a work area is suitable for occupation.
  • Reassurance air sampling may follow some very minor work on an asbestos-containing material. Or it may be appropriate when damaged asbestos is found.

Background Air Testing

  • Background testing provides baseline information on respirable fibres in a building prior to asbestos work taking place.

Personal Exposure Monitoring

  • In some instances employers are required to keep records of those who work with asbestos-containing materials.
  • Part of this record keeping can involve periodically measuring exposure levels of individual workers to respirable fibres.
