Asbestos Air Monitoring Edinburgh — independent evidence during work and before reoccupation
Background, leak, reassurance, personal and clearance air monitoring across Edinburgh and the Lothians, together with four-stage clearance and Certificates of Reoccupation where the complete process is required and satisfactorily passed.
Different air tests answer different project questions
Air monitoring should be selected from the question that needs answering, rather than added automatically.
Background monitoring
Establish conditions before work or provide a comparison point where justified.
Leak monitoring
Assess defined locations outside a controlled enclosure while relevant work is taking place.
Personal monitoring
Assess exposure associated with a particular person, activity and sampling period.
Reassurance monitoring
Provide evidence after a concern, cleaning activity or controlled task where the sampling objective is defined.
Formal clearance is more than an air test
Review site condition, work scope and readiness for detailed inspection.
Inspect the enclosure and work area carefully for visible dust, residue and debris.
Undertake prescribed air sampling after a satisfactory visual inspection.
Assess the former enclosure area after dismantling before completing the process.
0.010 f/ml is a clearance indicator — not zero fibres
The applicable Stage 3 clearance indicator is 0.010 fibres per millilitre. It should not be described as proof of zero fibres and is not the GB worker control limit.
The current GB control limit is 0.1 fibres/ml averaged over four hours, and HSE states that the control limit is not a safe exposure level.
Stage 3 clearance indicator
0.010 f/ml Different from the 0.1 f/ml four-hour workplace control limitThe certificate depends on satisfactory completion of the full applicable process
A satisfactory fibre count alone is not the complete four-stage clearance. Visual cleanliness, job completeness and final assessment are also part of the handback decision.
Late booking can delay enclosure handback and follow-on construction.
Air monitoring for licensed removal, occupied property and defined reassurance questions
Background, leak, personal or clearance monitoring may be relevant where asbestos work takes place beside occupied areas or programme-critical spaces.
Where applicable, the clearance process combines site-condition checks, thorough visual inspection, Stage 3 air monitoring and final assessment after enclosure dismantling.
A low reassurance result should not replace source assessment, material identification or controlled cleaning where those actions are still required.
