In New Zealand and Australia, HAC assessments for flammable fluids are covered under AS/NZS 60079.10 , which states that:

“The area classification should be carried out by those who understand the relevance and significance of properties of flammable materials and those who are familiar with the process and the equipment along with safety, electrical, mechanical and other qualified engineering personnel.”

Candidates seeking assessment for the unit standard “Classify Hazardous Areas” (US 17069) are required to have a relevant engineering or scientific discipline qualification at NZQF level 7 (i.e. Bachelor Degree or equivalent).

This Hazardous Area Classification Training course is aimed at engineers to develop the required competencies and achieve US 17069.

The course will:

  • Provide an introduction to the relevant gas or dust combustion, vapour/liquid equilibrium, fluid mechanics and dispersion analysis calculations.
  • Provide an overview of the national and international codes and recommended practices for the classification of Hazardous Areas.
  • Teach and practice a number of different techniques for establishing the degree and extent of the classified areas.
  • Enable assessment of the hazardous area required for releases outside the scope of prescriptive examples.
  • Provide an overview of the different design bases for the types of electrical equipment protection certifiable for use within specific hazardous areas.
  • Provide guidelines on documenting the HAC assessment.
