Asbestos air monitoring

Essential testing before, during and after asbestos remediation

An area cordoned off due to asbestos in the air.

Under the Control of Asbestos Regulations 2012, there must be monitorng of the asbestos particles in the air following any planned or unforeseen refurbishments or property repairs. 

What does our asbestos air monitoring service include?

It is crucial to undertake a comprehensive assessment of any area of asbestos removal or disturbance and our air monitoring services are accredited under UKAS and conform to ISo/IEC17025:2005. All air monitoring is managed in accordance withthe HSE guidance including HSG248 Asbestos: The analysts’ guide for sampling, analysis and clearance procedures At IOM we undertake the following:

  • Background monitoring in areas where asbestos materials are present.
  • Witnessing smoke tests and commissioning of enclosures.
  • Leak testing  to monitor if there is any breach in the enclosure.
  • Personal monitoring during asbestos activities.
  • Four stage clearance testing.
  • Visual inspections.
  • Reassurance monitoring.

Iit is vital to use an independent analytical company who are UKAS accredited to verify quality standards and to use a company who are independent of removal contractors; thus ensuring objective advice.

Please remember that allowing staff or the public to re-enter an area that has not been properly assessed can result in fatal exposure to asbestos fibres.


What is an asbestos four stage clearance?

Air Monitoring is preceded and followed by additional steps, which when combined are typically known as a 'Four stage clearance'. This process is implemented following the removal of asbestos and typically involves the following:

  1. A visual check of the site condition to ensure that planned removal is complete.
  2. A thorough visual review and inspection of the enclosed work area to ensure that no obvious risks exist.
  3. An undertaking of air monitoring within the enclosure to establish the presence of asbestos fibres, coupled with subsequent lab analysis.
  4. A further air-monitoring assessment upon dismantling an enclosure.

Only upon completion of all these steps can a certificate of re-occupation be issued.
