Asbestos Air Monitoring Melbourne
Asbestos air monitoring is a legal requirement for all friable asbestos removal works and should also be used for any bonded asbestos removals where:
- The works are indoors;
- The works may impact on others (for example if a minimum 10 metre exclusion zone cannot be established); or
- It is requested by neighbouring properties or other stakeholders.
Sometimes people also request air monitoring as an air quality check to allay concerns about a recent disturbance to asbestos materials or to assess a sites safety for airborne asbestos fibres.

What is Asbestos Air Monitoring?
Asbestos air monitoring measures the amount of respirable asbestos fibres in the air. The term 'respirable' means that the fibres are of a size and shape that can be deposited within the lungs. Air monitoring is usually carried out during or following asbestos removal works or as an air quality check.
While air monitoring usually shows that the respirable fibres are within the guideline levels in most cases (<0.01 fibres/mL), it is a proven way to put peoples minds at ease about asbestos removal works or asbestos safety. This can be very useful if for example there are concerned neighbours, adjacent workers or people that will re-occupy the asbestos removal areas following works. It may also be a legal requirement in some circumstances.
When is Air Monitoring Required?
Air monitoring for asbestos is a legal requirement in some circumstances, for example if:
- Friable asbestos is being removed;
- Asbestos removal is being carried out indoors; or
- Asbestos removal works may impact on others.
Greenlight are a specialist occupational hygiene company and will provide NATA accredited analysis of all samples. For our regular clients, we have industry competetive rates and can provide asbestos clearance certificates in combination with air monitoring as required at no additional cost.
Can Air Monitoring Results be Given in 'Real Time'?
The scene is familiar: I walk up to one of our trusty asbestos air monitoring pumps and there is a man looking at the numbers on the front panel with a worried frown. The number ticks up from 314 to 315. His eyebrows shoot up. "Those are minutes" I tell him. Understanding breaks as he nods his head. His eyes do not move from the monitor.
Currently there is not an easy or affordable way to measure airborne asbestos fibres in real time - the main problem is that the equipment that will do that is too costly. Instead we, as an industry, use a process where air is drawn over a membrane filter which is then analysed in a NATA accredited laboratory. Results are mostly given on a next day or same day basis depending on the time of completion.
There is some new tech just around the corner that will change all this (Artificial Intelligence combined with micro-photography!) but for now the industry cannot deliver results in real time.
What are the different kinds of air monitoring for asbestos?
Air monitoring for asbestos may be carried out for four main reasons:
Background Air Monitoring
This kind of air monitoring may be carried out as an air quality check or to set a baseline of airborne asbestos fibres. Some times this is carried out because people have a specific concern they would like assessed. For example a residential client we had recently found asbestos fragments in the sub-floor of his house. He wanted to know if this would affect the air quality in his home.
Control Air Monitoring
This kind of air monitoring is carried out during asbestos removal works to measure the effectiveness of the controls used. For bonded asbestos removal works, the controls are usually an exclusion zone with signage warning people at any entrances to the work area.
Control air monitoring is usually a public relations exercise to prove that works are safe, however it is also mandatory if friable asbestos is being removed, if works are carried out indoors or if works may affect others in the vicinity.
Clearance Air Monitoring
Clearance air monitoring is carried out within the asbestos removal area following works to prove that the area is safe to re-occupy. Clearance air monitoring is a legal obligation for any friable asbestos removal works or can be used to provide future occupants of the area with peace of mind.
Personal Exposure Monitoring
Exposure monitoring is carried out by fitting air monitors to representative workers with the cassette placed within the workers breathing zone. Greenlight use light-weight pumps fitted with a belt to the worker for maximum comfort and ease of work. Usually this kind of monitoring is carried out as part of a companies due diligence if asbestos exposure is a concern at a particular workplace. For example if workers work beneath an unsealed asbestos roof.
Who Can Perform Air Monitoring?
The regulations in Victoria require that a 'competent person' carry out these works, but what does that mean? The regulations very loosely define this as someone familiar with the use of equipment, asbestos hazards and measurement techniques with appropriate training and experience.
Air monitoring for asbestos is at essence an occupational hygiene assessment and as such should only be carried out by trained professionals. Make sure your consultant can tick these boxes as a minimum:
- They have a tertiary qualification in science, engineering or occupational hygiene;
- They work for an occupational hygiene company such as Greenlight;
- This one's important - they are not a former or current asbestos removalist (conflict of interest and unqualified); and ideally,
- They have been issued with an asbestos assessors license by one of the states (note: currently Victoria does not issue asbestos assessors licenses, however most other states do).
The asbestos air monitoring report should clearly state the qualifications of the technician towards the front of the document as well as containing a NATA accredited laboratory analysis report.

- Qualified independent air monitoring by licensed asbestos assessors;
