Having the knowledge and confidence that you're compliant really matters.
Let our team give you piece of mind that everyone will go home safe.

Are you meeting the standards for your industry?

If there is a possibility of fire or explosion in a hazardous area being caused by an ignition source than an assessment needs to be made.

Area classification is used to determine the possibility of an explosive atmosphere being present and can be assessed using AS/NZS 60079.10.1 for Gas & Vapour and AS/NZS 60079.10.2 for Dusts. These are not the only means to determine a hazardous area although are the preferred standards to be used in Australia. 

Selection, installation and maintenance of electrical equipment for explosive gas atmospheres are detailed in AS/NZS 60079.14. The requirements of this standard are mandatory and are called up in the applicable Acts or Regulations of each State or Territory in Australia. Inspection of equipment to AS/NZS 60079.17 gives the owner faith that the integrity of the equipment has not been compromised and that in the unlikely event a flammable atmosphere is present, the equipment will continue to keep the plant and equipment safe.

Hazardous Areas Design

In the design phase of your site, every effort is usually made to minimize the extent of the hazardous area but it may be difficult to ensure that an explosive atmosphere will never occur.

There are a few things to remember for the design of a hazardous area -

  • All the principals of AS/NZS 3000 & AS/NZS 60079.n series apply
  • Installing electrical equipment outside the zone eliminates the need to spend money on expensive certified equipment.
  • Gases are not dusts and dusts are not gases

Hazardous Areas Dossier

A hazardous areas verification dossier is a live, legal document that demonstrates your installation is compliant with the relevant standards. This should be available to everyone on site and should be updated as equipment is inspected, new equipment installed or classification changes.

Type B Gas Appliance

Type B appliances are commonly found in industrial sites and are defined in AS/NZS 5601.1 as an appliance with gas consumption in excess of 10 MJ/hour for which a certification scheme doesn’t exist.

Upon successful completion of the design, installation and commissioning the minimum requirements for ongoing Type B compliance is -

  • Appendix A - Technical Submission
  • Type B Gas Device Approval Certificate (Section 733)
  • Gas System Compliance Certificate (Section 734)
  • Operating Plant Compliance Certificate (Section 697)
  • Managing ongoing Type B compliance
