Following any licensed asbestos works, a Visual Clearance must be undertaken to confirm the work has been completed to a satisfactory standard, and areas are safe to reoccupy for normal use regarding asbestos exposure risks.
An Air Monitoring Clearance is required for any licensed works with friable materials, in addition to a Visual Clearance, to establish if affected areas are safe to reoccupy with regards to airborne asbestos fibres. Air Monitoring Clearances are often an effective way to address asbestos exposure concerns following any asbestos works or potential disturbance.
Our Experienced & Licensed Asbestos Assessors can undertake Clearances and issue Clearance Certificates for all sizes of project.
During a Visual Clearance all surfaces, ledges, fixtures and fittings in the asbestos work area are inspected for ACM dusts and debris.
Suspect dusts and debris identified must be removed before the area can be Cleared.
A typical Clearance inspection will include the work area, adjacent areas that may have been 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 for the presence of asbestos fibres.
All air samples are analysed by our NATA (National Association of Testing Authorities) accredited partner laboratory.
