Hazardous Area Classification

Hazardous Area Classifications can be conducted to any national or international standards for:


  • Flammable Gases, Vapours and Mists and,
  • Combustible Dusts
  • Tank Farms for Flammable & Combustible Liquid Storage




Hazardous Area Classification of gases, dusts and mists is generally conducted to AS/NZS 60079.10.1 (which supersedes the AS/NZS 2430.3 series and incorporates these as national annexes).


On occasion, reference is also made to other standards such as IP-15 or API-505 or selections from the NFPA series where further clarification may be required.





Hazardous Area Classification reports can take some time to draft and should be compiled by a competent person.

It is expected that a draft report will be sent, complete with draft Hazardous Area Classification drawings for client comment, prior to the issue of the final report.
