AS/NZS 2381.1:2005 Australian Standard, titled: “Electrical equipment for explosive gas atmospheres - Selection, installation and maintenance - General requirements” requires personnel who carry out testing and inspection of installations covered by the Standard to be competent.
A Competent Person is defined in AS/NZS 2381.1:2005 as ‘a person who can demonstrate a combination of knowledge and skills to effectively, efficiently and safely carry out activities in hazardous areas, covered by this Standard’.
The Joint Series of Competency Standards AS/NZS 4761:2003 Australian standard, titled: “Competencies for working with electrical equipment for hazardous areas (EEHA) - Competency Standards” sets out the general competencies required by personnel working with electrical apparatus in hazardous areas and the scope of technical training required to achieve those competencies.
The training required to meet the definition of ‘competent’ includes training on the various types of explosion-protection apparatus and the installation practices associated with each explosion-protection discipline, the relevant rules and regulations and the principles of area classification.
