Asbestos Air Monitoring & Clearances
The various Australian and New Zealand OHS/WHS/OSH Regulations prescribe requirements during and after an asbestos removal project. Air monitoring is conducted whilst removal works are occurring to ensure that control measures have been adequate and there has been no potential fibre release whilst works were undertaken.
At the completion of an asbestos removal project, an independent person is required to undertake a clearance inspection (some exemptions exist under state legislation pending quantity or type of material removed). These inspections ensure that all asbestos containing material and associated debris within the scope of the removal project has been removed appropriately. Clearance air monitoring is also undertaken to provide a certificate to acknowledge that the area is safe for re-occupation.
Greencap has several Licensed Asbestos Assessors (LAAs) across Australia who can complete the above works. With internal NATA accredited laboratories, Greencap are able to analyse asbestos air monitoring slides and issue NATA endorsed reports on the levels identified against the relevant exposure standards.
Greencap also has the ability to setup mobile, site-based laboratories – particularly for large and/or ongoing projects. This provides significant savings in terms of turnaround times and reduced project delays.
Whilst the majority of demand in this space is for asbestos related air monitoring and clearances, Greencap also has occupational hygienists experienced in lead and Synthetic Mineral Fibre (SMF) air monitoring. Whilst not as tightly regulated as asbestos, removal projects involving these hazardous materials pose potential risks. Air monitoring during these works provides assurance that control measures have been effective and that the area is safe for re-occupation following the completion of works.

Frequently Asked Questions
What is asbestos air monitoring?
Asbestos air monitoring is used to measure airborne asbestos fibres. Normally it is done daily during the period of a removal, outside the removal zone, to demonstrate that people are not being exposed to asbestos fibres. Following the removal, clearance air monitoring is conducted within the removal zone, to show that the area is safe to re-occupy.
Why is asbestos air monitoring important to my project?
Asbestos air monitoring is an important part of your project in order to demonstrate that the project is being managed safely.
Which pieces of asbestos air monitoring equipment does Greencap use?
Greencap uses air sampling pumps with a filter cowl attached which collects fibres. At the conclusion of the monitoring period, the filter is mounted on a microscope slide and inspected with a microscope to determine the number of asbestos fibres present on the slide.
