Asbestos Air Testing: When You Need It and What the Results Mean
Asbestos air testing measures airborne fibres to help establish whether asbestos work has been properly controlled. It is different from an asbestos survey, which identifies asbestos containing materials within a property.
When Is Air Testing Needed?
Air monitoring may be used during controlled asbestos work, after certain removal or disturbance, or where reassurance is needed following concerns about possible fibre release.
For licensed asbestos removal, air testing forms part of the formal four stage clearance process before an area can be returned to use. The clearance process also includes inspections and checks, not simply an air test.
In Glasgow and across Scotland, this can be particularly relevant when renovating older homes, tenements, garages, or properties where asbestos has been disturbed during building work.
What Do the Results Mean?
Results are generally reported as a concentration of fibres per millilitre of air. For four stage clearance, the applicable clearance indicator is 0.010 fibres per millilitre. This is a clearance threshold, not a declaration that an area contains absolutely no asbestos fibres.
The workplace asbestos control limit in Great Britain is currently 0.1 fibres per millilitre, measured over four hours. This is not a safe exposure level, and it should not be confused with the clearance indicator.
If you are unsure whether your property needs air testing after asbestos has been disturbed, professional advice can establish the appropriate testing route and provide documented results.
