Choose the test that answers the project question
Different types of asbestos air monitoring are designed to answer different questions and should not be treated as interchangeable.
Background monitoring
Establish conditions before work or provide a justified comparison point.
Leak monitoring
Check areas outside a controlled asbestos enclosure during relevant work.
Personal monitoring
Assess exposure associated with a defined person, activity and sampling period.
Reassurance monitoring
Provide evidence after a concern, cleaning process or controlled task.
Clearance air monitoring
Stage three of the four-stage clearance process after a satisfactory visual inspection.
Soil-project monitoring
Task-appropriate perimeter, personal or reassurance strategies during ground disturbance.
Independent evidence during and after asbestos work
Tees Valley applications include licensed enclosures, industrial maintenance, healthcare and education projects, accidental-disturbance checks, asbestos-in-soil works and reassurance following controlled remediation.
- Background and reassurance monitoring
- Leak and personal monitoring
- Four-stage clearance where required
- Clear analytical reporting and interpretation
Sequential assessment before reoccupation
- 1
Preliminary check
The site condition, enclosure integrity and relevant paperwork are reviewed.
- 2
Thorough visual inspection
The enclosure and associated areas are inspected for visible dust, debris and remaining material.
- 3
Clearance air monitoring
Air sampling is undertaken after the visual stage has been completed satisfactorily.
- 4
Final assessment
The area is assessed after enclosure dismantling before a Certificate of Reoccupation is issued.
Analytical support for local property and projects
Occupied buildings
Reassurance or project monitoring for homes, offices, shops, schools and healthcare premises.
Industrial premises
Monitoring for factories, workshops, warehouses, plant areas and operational maintenance.
Construction and remediation
Analytical strategies for asbestos removal, refurbishment, demolition and contaminated-land projects.
What to send for an accurate analytical scope
- The asbestos material and work category
- Plan of work and enclosure details
- Site plan and intended sampling locations
- Dates, shifts and handback requirements
- The specific exposure or clearance question
- Contact details for the site and removal team
The 0.01 fibres per cubic centimetre clearance indicator is not a general safe-exposure limit. The analytical strategy must match the work, material, enclosure, exposure question and legal requirements.

Middlesbrough air-monitoring FAQs
What is a four-stage clearance?
It is a sequential process including a preliminary check, thorough visual inspection, clearance air monitoring and final assessment after enclosure dismantling. All stages must pass before a Certificate of Reoccupation is issued.
Is all asbestos air monitoring UKAS accredited?
ASM is UKAS accredited under number 32982 for defined testing activities and locations on its current ISO/IEC 17025 schedule. The schedule defines the precise accredited scope.
Can an air test prove a building is asbestos-free?
No. Air monitoring measures airborne fibre concentration during the sampled period and conditions; it does not identify all asbestos-containing materials within a building.
When is reassurance monitoring useful?
It may help after a controlled incident or work activity where the question, area and sampling conditions are defined. It should not replace inspection, cleaning or an appropriate survey.
Plan the analytical strategy before work begins
Send the material, work method, enclosure arrangements, programme, site plan and monitoring objective.
