A Clearance Certificate is usually required after asbestos removal, to confirm the work has been completed to a satisfactory standard and the areas are safe for reoccupation and normal use. All areas must be visually inspected and 'cleared', and an Air Monitoring Clearance is also often required or requested.
During a Visual Clearance all surfaces, ledges, fixtures and fittings in the work area are inspected for asbestos dusts and debris. The photograph above shows asbestos material debris stuck to a nail head, which must be removed before the area is cleared
An Air Monitoring Clearance determines if airborne fibre levels are below 0.01f/ml
(fibres per millilitre) of air, 10 times less than the asbestos National
Exposure Standard (NES) of 0.1f/ml. The NES for a harmful substance is a
concentration that should not cause ill health effects to most people with
exposure for 8 hours per working day.
BENSS provides independent clearances and project management for all size projects, from single small areas to ongoing large scale removals programs. Our consultants work closely with clients and contractors, using our expertise to identify potential problems before they occur and ensure areas are safely back in operation as soon as possible.
All air samples are analysed by our NATA (National Association of Testing Authorities) accredited laboratory, with results issued as Fibre Count Certificates.
