A Clearance Certificate is required for licensed asbestos works.
Following any licensed asbestos works, a Visual Clearance Inspection must be undertaken, to confirm the work has been completed to a satisfactory standard, and areas are safe for normal use. All Clearance inspections must be conducted by a competent person (typically an Asbestos Assessor) engaged independently of the asbestos contractor.
Where higher-risk ‘friable’ materials are removed, asbestos air monitoring will usually be required. The area can only be opened for normal use following satisfactory monitoring results, which must be included with the Clearance Certificate.
Air Monitoring Clearances are often an effective way to address asbestos exposure concerns following any asbestos works or potential disturbance, even if not a legal requirement.
Our experienced & licensed Asbestos Assessors can assist with Asbestos Air Monitoring and Clearance Inspections, for all asbestos projects.
Visual Clearances
During a Clearance Inspection all surfaces, ledges, fixtures and fittings in the asbestos work area are inspected for potential asbestos dusts and debris.
Any suspect materials identified during the inspection must be removed before the area can be cleared, and in most cases this will include all loose dust and debris.
A typical Clearance Inspection includes the work area, adjacent areas potentially impacted, waste transit routes, and the surrounds of any waste containers, skips, or vehicles.
Air Monitoring Clearances
If an Air Monitoring Clearance is required, the asbestos work area must not be passed for reoccupation until airborne fibre levels are below 0.01f/ml (fibres per millilitre) of air.
Air samples are taken by drawing a known volume of air over a filter, which is then analysed under a microscope for asbestos fibres.
All samples are analysed by our NATA (National Association of Testing Authorities) accredited partner laboratory, and NATA accredited analysis certificates are provided with the report.
