The role of an Accredited Hazardous Areas Auditor

As previously mentioned, in Queensland a person must not connect or reconnect an electrical installation located in a Hazardous Area, to a source of electricity after electrical installation work has been performed on the electrical installation unless—

a)the electrical work has been inspected by an accredited auditor; and

b)the accredited auditor has confirmed that the electrical installation, to the extent it is affected by the electrical work, has been tested to ensure it is electrically safe and complies with the requirements of the wiring rules and any other standard applying under this regulation to the electrical installation.

ConclusionTo say a piece of equipment is compliant is to say that:

•The installation has been correctly classified•The equipment selection is correct•The equipment has been installed as per the certificate of conformity and/or manufactures specifications•Accessories and terminations comply, have been done correctly and, where relevant to a correct torque •Equipment has been electrically tested and deemed safe•The inspector is trained, competent and authorised
