Major hazard facilities

Major hazard facilities are sites that store, handle and process large quantities of hazardous materials, such as oil refineries, chemical plants or large fuel and chemical storage areas.

Operators of major hazard facilities must:

  • identify all major incidents and major incident hazards for the facility
  • conduct and document a safety assessment of the facility's operation, that includes a comprehensive and systematic investigation and analysis of all aspects of potential risks to health and safety
  • implement control measures that eliminate or minimise the risk of a major incident occurring
  • prepare an emergency plan
  • establish a Safety Management System
  • prepare a safety case which demonstrates that the Safety Management System will control risks arising from incidents and incident hazards. It also needs to assess the adequacy of measures required to control risks associated with the occurrence of major incidents.


    Organisations or individuals must inform us if they have, or are likely to have, any chemical in excess of 10% of the threshold quantities set out in Schedule 15 of the Work Health and Safety Regulations 2012 (SA).

    Your notification will ensure that all potential major hazard facilities are made known to us and will allow us to determine if your site is a major hazard facility. If we do, we will send you a licence application, set an  annual fee for a 5 year licence, request a safety case and evidence of registration of your business, to be completed within 24 months of our determination.
