Health surveillance is monitoring a person to identify changes in their health resulting from exposure to a hazardous substance.   

Health surveillance may detect harm to health at an earlier stage, allowing controls to be improved to protect workers’ health or earlier medical treatment. 

If the health of a person is at risk as a result of exposure to asbestos at work, the employer must ensure that health surveillance is carried out in accordance with the Occupational Safety and Health (OSH) Regulations 1996. Regulation 5.1 defines ‘health surveillance’ and regulation 5.23 requires an employer, main contractor or self-employed person to provide health surveillance to a worker in relation to hazardous substances.

Activities that may present a health risk due to asbestos exposure, and where health surveillance should be carried out, include:

• Removal or handling of friable asbestos materials (‘friable’ means the asbestos containing material is in a powder form, or can be crumbled by hand pressure);
• Handling asbestos using unsafe practices (eg cutting with power tools - note that this is not permitted under OSH legislation); or
• Activities where asbestos exposure is at or above the asbestos exposure standard (8 hour time weighted average of 0.1 fibres/mL)

Please note that excessive exposure to asbestos must be reported to WorkSafe (OSH Regulation 5.40) and exposed people must be informed (OSH Regulation 5.41).

All air has a very low background level of asbestos. Low risk activities such as working in asbestos cement buildings, or maintaining such buildings using safe work methods, do not require health surveillance.

Health surveillance must be conducted by an Appointed Medical Practitioner (AMP), a doctor with adequate training and experience in relation to asbestos and who has been appointed by the employer after consultation with the worker/s. WorkSafe has a list of doctors who conduct health surveillance work, although not all such doctors are listed.

If the doctor you choose has not conducted health surveillance for asbestos previously, it is essential for them to contact WorkSafe’s occupational physician on 1300 307 877 to ensure they are aware of their duties under OSH legislation. 

Should there be any indications of adverse health effects from asbestos exposure, the AMP can refer the person to a respiratory physician for an assessment.

Following the baseline assessment, the frequency of health surveillance is based on medical advice and depends on the individual’s risk profile.
