Can You Store Diesel in a Polyethylene Tank?

Yes, but only if the tank is specifically manufactured for diesel storage using diesel-grade polyethylene. A standard poly rainwater tank is not suitable and should never be used for fuel storage.

Polymaster’s poly diesel fuel tanks are made from diesel-grade polyethylene, built for Australian conditions, and available in single or double-walled configurations from 5,000L to 10,000L.

What Does AS1940 Require for Poly Diesel Tanks?

AS1940:2017 is the Australian standard for the storage and handling of flammable and combustible liquids. It specifically permits fire-retardant polyethylene tanks for diesel storage in Australia, provided the following requirements are met.

• Purpose-built tanks only: repurposed containers, including IBCs, do not comply
• Maximum 10,000L: for farm use on open land greater than 2 hectares
• Bunding required: secondary containment of 110% of tank capacity must be in place; self-bunded diesel fuel tanks satisfy this requirement in a single unit
• Separation distances: from buildings, boundaries, and ignition sources must be observed
• Labelling: with contents and hazard class is mandatory on every tank

Getting this right from the start protects your business, your property, and your fuel supply. A non-compliant setup can create serious liability exposure and may void your insurance in the event of a spill or fire.

Polymaster’s self-bunded diesel fuel tanks are designed to meet AS1940 diesel storage compliance requirements straight out of the box, with self-bunded options available in the Ranger, Quantum, and Essential series.
