Incorporating Successful Asbestos Practices

ASB Environmental Ltd have developed efficient working practices and effective techniques when removing asbestos containing materials since company inception. Developing innovative removal procedures to incorporate into future projects is a key objective for ASB Environmental in moving forward in this competitive industry.

Regularly audited by the HSE, we ensure the exemplary standards of Health & Safety required are achieved across the board and that our work method complies with that detailed within the Control of Asbestos Regulations (CAR) 2012. These regulations stipulate the techniques, procedures and methods to be used when working with, removing and disposing Asbestos materials. Basic requirements when as follows: –

  • Risk assessment and preparation of method statements
  • Notification of Licensable or Notifiable Non-Licensed asbestos materials
  • Maintaining accurate employee records i.e. Training Portfolio, Exposure Records
  • The use of Personal and Respiratory Protection Equipment (PPE) & (RPE)
  • Segregation of Asbestos working zones i.e. Respirator Zones and Asbestos Enclosures
  • Recognised Industry Removal Techniques
  • Waste disposal to Licensed Waste Transfer Station
  • Decontamination of plant, equipment, trained operatives and all surfaces

Each of the above control measures are implemented and designed to protect asbestos operatives when removing asbestos, clients, present and future occupiers from exposure to asbestos fibres.

It is not always necessary to use a licensed contractor as non-licensed contractors can remove some asbestos materials. In particular the removal of good condition non-friable products containing Chrysotile asbestos such as cement products, floor tiles and roof sheets.

It is however considered best practice to use licensed asbestos specialist, particularly for complex processes such as removing artex from ceilings or removing floor tiles from concrete floors or in areas of high risk such as communal areas. As failure to implement, the complete package of safety control measures can cause considerable public exposure to asbestos fibres.

Air monitoring

If you have concerns regarding the presence of asbestos, the level of risk can be assessed via air monitoring. Most asbestos removal works will require air monitoring and 4 stage clearance testing, which by law must be undertaken by an independent UKAS accredited laboratory. ASB Environmental Ltd can supply this indoor air quality service for your peace of mind.

Air monitoring services include:

Personal monitoring – where operatives’ exposure is measured within an enclosure during asbestos removal works to check that the protection factor of their respiratory protective equipment (RPE) is not exceeded.

Four-stage clearance – the procedure carried out by the UKAS accredited laboratory following the removal of asbestos. A visual inspection must be conducted by the analyst to ensure that the area has been cleaned to a satisfactory standard and is suitable for re-occupation. Clearance air monitoring is then conducted inside the enclosure to check that airborne fibre levels are below the recommended limit. Once satisfactory results are achieved, the analyst will issue a certificate of re-occupation.

Reassurance monitoring – may be conducted in certain circumstances (such as when an enclosure has been removed on completion of asbestos remedial works) to confirm that the airborne fibre levels are satisfactory.

Compliance monitoring – conducted to check that exposure to workers does not exceed the control limit. The control limit can be calculated over a 10 minute or 4 hour period.

Background monitoring – generally conducted to check that fibre levels in the air are below the recommended level. This can occur during minor remedial works or when accidental damage has occurred to ACMs. Background monitoring can also be used as part of an over-all monitoring strategy to manage asbestos-related risk.

Leak (enclosure check) monitoring – performed outside the enclosure while asbestos removal work is in progress to check that control measures are adequate.
