Hazardous Area Classification

$2,525.00 +GST

This course can be run online or face-to-face in New Plymouth.

The classification of areas where an explosive atmosphere might arise is required to permit the proper selection and installation of equipment for use in such hazardous areas. Explosive atmospheres result from the presence of flammable gases, vapours and dusts. The aim of this 3-day course is to develop the competencies required to perform a Hazardous Area Classification based on the requirements of AS/ NZS 60079.10.1:2009 and AS/ NZS 60079.10.2:2016 with supplementary information supported from EI15 4th Edition and IEC 60079.10.1:2015.

This course awards US 17069 and meets the competencies of AS/ NZS 4761.1. It has strict pre-requisites that must be met before your registration on the course is confirmed. This is to ensure your level of understanding is adequate to meet the preconditions for assessment to AS/ NZS 4761.1 2018 Competencies for Electrical Equipment in Hazardous Areas. 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).

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.
