If a commercial building was constructed prior to 31 December 1989 and asbestos is present or likely to be present, a building audit and asbestos register is required.

A person with management or control of a workplace must ensure that all asbestos or asbestos containing material at the workplace is identified, the location of the asbestos clearly indicated and recorded in a register and an asbestos management plan provided if asbestos is identified or is likely to be found at the workplace from time to time. This task must be carried out by a competent and suitably trained person such as Occupational Hygienists or Licensed Asbestos Assessors.

The register must be kept up to date and be readily available to all workers, including contractors, at the workplace. This register must be reviewed at least once every five years, or earlier if asbestos or ACM has been disturbed/removed/sealed or enclosed, further asbestos or ACM is identified, or if the asbestos management plan for the workplace is reviewed.
