Asbestos Air Monitoring

Confirming the Air Is Safe, Before and After Removal

Asbestos Air Monitoring – Licensed Assessors Across Regional Victoria

Asbestos air monitoring is the process of measuring airborne asbestos fibre concentrations before, during and after asbestos-related works. Our licensed Asbestos Assessors use calibrated air pumps and collection filters to gather samples, which are then analysed by a NATA-accredited laboratory. Results are compared against the regulatory limit of 0.01 fibres per millilitre to confirm whether the environment is safe.

Air monitoring is a core component of the post-removal asbestos clearance certificate process for Class A removals, and is also commonly requested during Division 6 pre-demolition works and sensitive removal projects in occupied buildings.

When Is Air Monitoring Required?

Legally required for all Class A (friable) asbestos removal
Strongly recommended for Class B works conducted indoors or in enclosed spaces
Where disturbance to areas beyond the work zone is possible
In sensitive environments such as hospitals, schools or aged care facilities
When insurers, principal contractors or building owners require independent verification

The Four Types of Air Monitoring We Provide

Background Monitoring – establishes normal fibre levels before any works begin
Control Monitoring – detects fibres escaping the removal area during works
Clearance Monitoring – confirms the area is safe for reoccupation, forming part of the clearance certificate process
Personal Exposure Monitoring – measures individual worker fibre exposure during removal activities

Types of Air Monitoring We Provide

Under NOHSC:3003 (2005), four distinct types of asbestos air monitoring are recognised. ProCheck Services provides all four, depending on the nature of your project:

Type of Monitoring	Purpose	When It’s Used
Background Monitoring	To establish the normal airborne fibre levels prior to asbestos work	Conducted before any asbestos removal or disturbance to determine baseline air quality
Control Monitoring	To detect asbestos fibres that may escape the removal area or enclosure	During friable (Class A) removal where negative pressure enclosures are used, and during non-friable (Class B) removal at site boundaries or adjacent areas to confirm fibres are not escaping the work zone
Clearance Monitoring	To confirm the area is safe for reoccupation following asbestos removal	After final visual inspection and cleaning of the work area (particularly for Class A removal), prior to re-entry, reoccupation, or demolition
Personal Exposure Monitoring	To measure the airborne asbestos fibre exposure of individual workers	During asbestos removal activities, especially in high-risk environments or where required by the employer

Compliance Standards We Work To

Part of a Broader Compliance Picture

Air monitoring typically forms one component of a broader asbestos compliance program. Whether your project also requires a Division 5 audit, an asbestos management plan or a full hazardous materials audit, ProCheck can coordinate all of these services for your site.
