OHS compliance for Class 3 Flammable Liquids in Western Australia 

Sep 12, 2019 Posted by Walter Ingles

This blog is for business owners, operators and HSE Managers who are responsible for Dangerous Goods compliance at workplaces in Western Australia. Most Australian states and territories follow the Model WHS Legislation released by Safe Work Australia in 2012, however the government of WA issues and enforces their own legislation. This blog will help you understand your compliance obligations as they relate to Class 3 Flammable Liquids and other Dangerous Goods. 

IMPORTANT: The state of Western Australia is currently in the process of updating their WHS legislation to bring it in line with the legislation developed by Safe Work Australia. The legislation is still under review by the DMIR.  


Work health and safety regulation in WA 

Work health and safety laws in Western Australia are administered and enforced by WorkSafe WA, a division of the Department of Mines, Industry Regulation and Safety. There are two key pieces of legislation that relate to Class 3 Flammable Liquids: 

The state legislation sets out the duties of a business owner or operator to provide a safe workplace, as well as identifying and controlling risks and hazards. Some key responsibilities (unique to WA) that relate to Class 3 Flammable Liquids include: 

  • Assessing the risks of exposure to chemicals and creating formal assessment reports to outline the severity of the risk, and the actions that have been taken to either eliminate or control them. These reports must be updated at least once every 5 years and be available during WorkSafe Inspections. 
  • Specific requirements for inducting and training anyone likely to exposed to hazardous substances during the course of their work, or when visiting the site. 
  • Ongoing monitoring of risks associated with hazardous substances and sharing the results with the workers and contractors who are actually handling (or working near) the chemicals.

Dangerous Goods 

Worksites who use and store Class 3 Flammable Liquids also have additional obligations under Dangerous Goods legislation. In Western Australia, Dangerous goods are regulated by the Department of Mines, Industry Regulation and Safety (Dangerous Goods branch).  

Legislation includes: 

  • Dangerous Goods Safety Act 2004 — outlining the duty of all persons who are involved in storing, handling or transporting dangerous goods to take all reasonable measures to minimise the risk to people, property and the environment from the goods. Fines start at $50,000 for non-compliance. 
  • Dangerous Goods Safety (Storage and Handling of Non-explosives) Regulations 2007 — outlining duties relating to chemical spills, segregation, licensing a dangerous goods site, placarding, manifest and Dangerous Goods site plan, fire control equipment, impact protection for Dangerous Goods stores, underground petroleum and fuel storage, ventilation, record keeping and emergency planning.

Australian Safety Standards 

To fulfil all your Dangerous Goods compliance obligations in the state of Western Australia, we also recommend making Australian Standard AS1940:2017 – The storage and handling of flammable and combustible liquids the foundation of site handling and storage practices.
