This guidance helps businesses and organisations understand their obligations and good practice when using tertiary containment systems to contain pooling substances.

Key points

  • You must manage the risks of hazardous substances in your workplace.
  • Based on your assessed risks, a tertiary containment system can contribute to managing risks of pooling substances at your workplace if secondary containment fails.
  • If a tertiary containment system is installed, the risks to the health and safety of people from any plant or structure must be eliminated or minimised.
  • Through a whole-of-workplace approach, tertiary containment systems can make a meaningful difference to emergency management.
