This unit covers the explosion-protection aspects of designing electrical power, control and instrumentation systems and installations. It requires the ability to identify hazardous area zones from classification diagrams, or from examples of previously classified areas or those given in Standards, and to select and locate explosion-protected equipment and wiring systems and other items that may influence the explosion-protection technique, classify areas where flammable/combustible potentially explosive materials may exist. It requires the ability to gather and analyse data relative to explosion hazards, determine the extent of risk and establish and document zones and establish design briefs and to pursue economical and effective design solutions

This Skill Set is directly equivalent to the Units .16 Classify hazardous areas, 2 .17 Plan electrical installations for hazardous areas and 2 .18 Design explosion -protected electrical systems and installations  in the Australian/New Zealand Standard AS /NZS 4761 .1 Competencies for working with electrical equipment for hazardous areas  (EEHA ) Part 1 : Competency Standards
