Hazardous Area Classification

Our experienced hazardous engineers can inspect, classify and audit hazardous areas.

We have 3 hazardous area engineers and they conduct work all over Australia.

We conduct;

  • Hazardous Area Classification
  • Hazardous area compliance checks
  • Hazardous Area audits
  • Hazardous Area Inspections including ‘H’ Class Inspectors
  • Hazardous Area Design
  • Training Audits
  • Training Gap Analysis


Area classification is a method of analysing and classifying the environment where explosive gas atmospheres may occur so as to facilitate the proper selection and installation of equipment to be used safely in that environment.


AS/NZS 60079 Part 10-1: Classification of areas – Explosive gas atmospheres and

AS/NZS 60079 Part 10-2: Classification of areas – Combustible dust atmospheres


Standard intended to be applied where there may be an ignition hazard due to the presence of flammable gas or presence of flammable gas or vapour, mixed with air under normal atmospheric conditions but does apply to:

  • Petrochemical Plants
  • Chemical Plants
  • Gas Installations
  • Dust Industries – (Timber Mills, food manufacture, wheat storage and Transport, Coal storage and Transportation).


Methods of Classification

The basic elements for establishing the hazardous zone types are:

  • Identification of the sources of release
  • Determination of the grade of release
  • Determination of the release rate, velocity, etc
  • Determination of the type of area (openness)
  • Degree and availability of ventilation
  • Use of an appropriate code or calculations to determine the extent of zone
