EEHA Audits

An experienced hazardous area auditor must have a detailed understanding of the relevant Australian standards, acts and regulations.

At MOXI HA Services our hazardous area installation auditors and electrical engineers have extensive knowledge of all the specific design and installation requirements for electrical installations within hazardous areas.

We are accredited in the design, classification, inspection and maintenance of electrical equipment in hazardous areas, so whatever your needs our hazardous area installation auditors come armed with the right experience and competency, backed by the infrastructure to support you, the client.


A new plant or a plant review aimed at reducing zoning or for modification of an existing facility, our skilled, competent EEHA experts provide cost-effective Hazardous Area Classifications for your business. MOXI HA Services will provide you with delineation drawings, classification reports and supporting documentation that ensures your site demonstrates compliance with AS/NZS 60079 Standards.

Hazardous area classification is a method of determining the likelihood with which an explosive atmosphere may occur in a given location. This then helps to determine the appropriate requirements for the selection and installation of equipment to be used in that location.

When classifying explosive gas atmospheres, MOXI HA Services are able to provide assistance in applying the principles of AS/NZS 60079.10.1 for site classification to ensure the appropriate apparatus is selected. This standard includes the Australian examples previously given in the AS/NZS 2430.3 series and also accepts the use of other industry standards, such as API RP505 and IP15.

For areas where the hazard is an explosive dust atmosphere, MOXI HA Services compliance engineers are able to provide the best available advice on the application of the current AS/NZS 60079.10.2 classification requirements.

Hazardous area classification is required for a range of potentially hazardous areas such as LNG, Gas, Oil, Mining, aircraft hangars, petrol stations, paint-finishing locations or flour mills, the list goes on.

Conformity Assessment Document

Conformity Assessment is the demonstration that specified requirements relating to a product, process, system, person or body are fulfilled.

In the context of installing electrical equipment in a hazardous area, AS/NZS 60079.14 requires “assurance of conformity of equipment”. This is achieved by the use of equipment certified as complying with the relevant IEC, AS/NZS or AS hazardous area equipment standards. In Australia, according to AS/NZS 60079.14, only certificates issued under a scheme meeting certain requirements, such as the following, are acceptable.


Equipment certified under alternative schemes or to other standards may be used in situations where suitable equipment with acceptable certification is not practically obtainable.

In the 2005 edition of AS/NZS 2381 Part 1 Clause the use of Conformity Assessment Documents [CADs] was introduced as a potential justification for the use of equipment certified to an alternative standard. This has been expanded with the addition of Annex ZD to AS/NZS 60079.14 introduced in 2009 and may be applied where a certificate other than ANZEx or IECEx can be shown to provide an 'equivalent level of safety' to either an ANZEx or IECEx Certificate of Conformity.

Equipment approved for use in Hazardous Locations by a NRTL (e.g. FM, UL or CSA) in North America, or with a Type Examination Certificate issued in accordance with the ATEX directive 94/9/EC are examples of equipment certified to an alternative standard which may be suitable for Conformity Assessment.
