Laboratory asbestos air testing: air monitoring to support regulatory compliance, with fast results for worksites and post-work checks.

Asbestos Air Monitoring in Buildings: Purpose, Requirements and Testing

Summary: Asbestos air monitoring measures the concentration of airborne asbestos fibres inside a building. It is used before, during and after work to assess potential exposure, check the effectiveness of containment and support the safe return of premises to use.

BJL Laboratoires has provided airborne asbestos fibre measurements in buildings for more than 30 years, monitoring air quality in areas affected by asbestos-containing materials. These measurements help assess airborne fibre levels during construction, maintenance and asbestos removal work, and check the effectiveness of protective measures and containment.

What is asbestos air monitoring?

Asbestos air testing involves collecting and analysing air samples to detect and quantify airborne asbestos fibres. It provides information about airborne contamination in a building and supports the assessment of potential exposure for occupants and people working on the premises.

Why measure airborne asbestos fibre concentrations?

Asbestos air monitoring helps to:

• Quantify the concentration of asbestos fibres in the air
• Assess potential exposure in the areas concerned
• Check the effectiveness of containment and protective measures
• Monitor conditions during asbestos removal or maintenance work
• Document regulatory compliance and support the resumption of activities

When is asbestos air monitoring carried out?

Airborne asbestos fibre measurements may be carried out in several situations:

• Before work, to establish initial conditions and background concentrations
• During work, to monitor containment effectiveness
• After work, as part of clearance and reoccupation checks
• In adjacent areas or neighbouring rooms, for environmental monitoring

These measurements form part of the asbestos air testing services used to monitor worksites, assess compliance and track air quality in buildings.

How is asbestos air monitoring carried out?

A monitoring programme generally involves the following stages:

1. Define a sampling strategy suited to the building and the planned work.
2. Install air sampling pumps and suitable filter holders.
3. Collect samples in the designated areas.
4. Analyse the samples in the laboratory.
5. Interpret the results and issue a clear measurement report.

Analytical methods used

Air samples are collected using sampling pumps and suitable filters. For the French regulatory measurements in buildings covered here, asbestos fibre analysis and counting are performed using transmission electron microscopy (TEM).

The French Order of 19 August 2011, as amended refers to NF EN ISO 16000-7 for the sampling strategy and NF X 43-050 for sampling and the relevant analytical procedures.

Optical microscopy should not be presented as an interchangeable alternative for these regulatory measurements.

Frequently asked questions about asbestos air monitoring

What is the difference between asbestos material testing and air monitoring?

Material testing investigates asbestos in a solid sample. Air monitoring measures the concentration of asbestos fibres suspended in the air.

Why carry out air monitoring after asbestos removal?

It checks whether the measured airborne asbestos concentration meets the applicable requirements before the area is returned to use. It forms part of the required checks and does not replace other assessments, such as visual inspection where required.

Who may need asbestos air monitoring?

Project owners, asbestos removal contractors, building managers, engineering consultancies and professionals working on asbestos-containing materials may require these measurements.

How long does it take to receive the results?

The turnaround time depends on the type of assignment, the number of samples and the urgency of the request.
