On-Site Workshop: 3-Day How to Apply Hazardous Area Australian Standards (Group II) 2018

This workshop provides a sound understanding of electrical compliance and your responsibilities in Group II (flammable gases, liquids and vapours) hazardous areas.

Potential sources of ignition are often taken into hazardous locations where flammable liquids, gases, vapours and dusts are generated, processed, handled and stored. These flammable substances can easily ignite from an arc, spark or heat. It is essential you avoid accidental ignition of these flammable substances.

This workshop is suitable as first time, refresher and continuing training for personnel requiring a comprehensive understanding of electrical installations in hazardous areas. It is suitable for those who need a detailed understanding of how to achieve hazardous area electrical compliance, in particular electricians, electrical engineers, instrument engineers, control engineers and electrical regulators.

Trainees will receive an introduction to hazardous area legislation, a detailed understanding of how hazardous areas are classified, and sources of ignition based on current Australian Standards. This workshop also provides trainees with a sound understanding of the relevant Australian Standards used to select, install, inspect, test and maintain hazardous area electrical installations.
Ensure you remain compliant* and maintain your hazardous area skills and knowledge by booking this essential workshop today.
