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.”

This Hazardous Area Training course is aimed at people who would like to develop the required competencies for classification of hazardous areas involving flammable fluids and dusts. 

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.

The competency requirements for hazardous areas are further detailed in AS/NZS 4761, which states that a candidate seeking assessment in this unit shall have been deemed competent to gather and analyse technical data in a relevant engineering or scientific discipline at AQF 7 or NZQF Level 7, which is equivalent to a bachelor’s degree.  

All attendees who attend and pass the course will be given a certificate of attendance. However, only those with a suitable qualification for the competency requirements listed in AS/NZS4761 (Bachelor’s degree or equivalent) will be allowed to complete the post-course case studies and be awarded their certificate of competency. 

Attendees in New Zealand will also be awarded the unit standard US 17069 on successful completion of their case studies.
