Resource Hub
The Hierarchy of Spill Controls is a well-established framework used across Australian workplaces to
manageand mitigate chemical spill risks. Based on the broader WHS hierarchy of controls, it is supported
by EPA guidelines and key Australian Standards, including AS/NZS 3833:2007 and AS/NZS 1940:2017.
This resource helps organisations to:
Implement control strategies – Apply measures from elimination through to PPE, tailored to specific
spill scenarios
Maintain compliance – Align with WHS Regulations and EPA containment protocols
Select appropriate products – Match Akuna’s spill control solutions to each level of the hierarchy
for effective risk reduction
Control levels include:
Elimination – Remove hazardous substances entirely
Substitution – Replace with safer chemical alternatives
Engineering controls – Use bunding, spill pallets, and containment systems
Administrative controls – Train personnel, conduct regular audits, and display
clear procedures
Personal Protective Equipment (PPE) – Provide suitable gear to ensure safe
and effective spill response
Use this framework to strengthen your spill risk management and support a safer,
more compliant workplace.
