This unit of competency specifies the outcomes required to visually inspect and use a range of measuring devices to undertake the monitoring of airborne asbestos fibres in the workplace as an integral part of identifying hazards, assessing risks, monitoring the effectiveness of controls, and ensuring that the workplace is free of visible asbestos fibres and air monitoring results are at acceptable levels prior to reoccupation.
The unit includes the planning of the monitoring process, the selection and use of processes and air-monitoring equipment, the conduct of the assessment process, and the proper handling and interpretation of results.
Asbestos assessment and air monitoring are required during all friable (Class A) asbestos removal and for non-friable (Class B) asbestos removal where a risk assessment indicates that airborne asbestos fibres may result from the removal activity.
Licenses are required in most states and territories. Work must be completed according to relevant legislative, code of practice, industry, customer and organisational requirements, including work health and safety (WHS) policies and procedures. Analysis of samples must conform to National Association of Testing Authorities (NATA) or other accredited laboratory requirements and standards.
The model WHS regulations and the Code of Practice: How to safely remove asbestos (2018) outlines regulatory requirements for clearance inspections, air monitoring (the Membrane Filter Method for Estimating Airborne Asbestos Fibres) and certification.
Candidates are advised to check for specific jurisdictional regulatory requirements.
