AANZ are able to undertake air monitoring for a multitude of different reasons:
- Background monitoring – undertaken outside of the removal enclosure, before and during the removal process to ensure that the airborne fibre count remains the same during the works as it was before works commenced. This also confirms the presence of any leaks in the enclosure so that they can be remediated immediately.
- Reassurance monitoring – undertaken when asbestos is present but not being removed. When an asbestos containing material is staying in situ we are able to monitor the air around it to ensure that is it not releasing airborne fibres.
- Clearance monitoring – undertaken once removal works have been completed and all dust and debris have been cleaned up. Clearance monitoring is required before a certificate is issued allowing people into the area after the removal works have been completed.
- Personal monitoring – can be carried out at the request of the contractor to ensure that the workers in the enclosure are not being exposed to high levels of asbestos fibres in the air outside of their face masks. It is also best to carry out personal monitoring to determine the effectiveness of the controls the removalists are using to reduce the release of fibres inside the enclosure.
