Can I use a poly tank to store diesel on my farm?
Ricegrowers' Association of Australia has on its website the Guidelines
for Storing Fuel on Farms. The guide is published by the Australian
Institute of Petroleum. This
guideline includes a checklist that fuel distributors use, to decide
if they will deliver to your above ground bulk diesel storage unit.
(Its possible this link could change, so search Google for "Guidelines
for Safe Above-Ground Fuel Storage")
The fuel distributor will want to ensure that the tank meets the AS1692
Standard (Tanks for Flammable & Combustible Liquids), there is no rust,
there is good drive-in access, the site of the tank is clear, and not
near any hazards, and that the ladder to get to the filling point meets
the OH&S requirements in your state, and the requirements of AS1657
(ladders & handrails). More detail can be found in their fuel storage
For diesel, the maximum tank size they allow is 10000 litres (see AS1940
You should contact the EPA (Environment Protection Authority) in your
State for other requirements in relation to bunding, spills, and location
near waterways. You should also refer to AS1940
- The storage and handling of flammable and combustible liquids.
Unfortunately poly tanks don't pass the flame test in AS1692 - and the
standard refers only to metal tanks. Attempts are being made to allow
poly tanks to qualify for the Standard, as they are in NZ, but at this
stage they do not meet AS1692. This is a great shame because the major
safety problem with diesel storage tanks is rust, and our poly tanks
never rust! We have a range of transportable steel bunded
fuel storage tanks available. Most mining sites require a bunded
Its not illegal to have a poly diesel storage tank, its more to do with
whether or not the fuel distributor will fill it for you. Some fuel
distributors will deliver to a site with a poly tank, so check with
your local distributor. In our experience if one dealer/distributor
won't, then try their competitor, they probably will.
However, mounting our tanks on a trailer or truck, will allow you to
cart diesel to your site. We have purpose-built diesel
trailers, or our poly tanks can be mounted to a gal skid for pushing
onto a tipper or flat-bed truck. Have a look at the rules
for transporting Diesel .
Please note that
the above standard only applies to class 3 flammable liquids as defined
in ADG Code Clause 1.4.9. Diesel is a C1 liquid, except when its
being transported. Comments below refer only to diesel (not other
flammable liquids). If diesel is stored with other flammables the rules
AS1940 specifies a maximum size of 10000L for diesel storage, provided
its outdoors, on open land (at least 2ha) and not near anything combustible.
It's a good idea to have an appropriate fire extinguisher nearby when storing any flammable liquid.
In enclosed areas
like sheds and warehouses, the maximum size is 500L, but this
changes depending on the surrounding items like walls and boundaries,
and the type of establishment, eg school, laboratory, commercial building..
A warehouse can store diesel up to 2000L depending on the available
floor space. Please refer to the standard for more detail.
A bund is
a containment area or wall, that can hold the diesel, in the event of
a spillage or tank failure. It needs to be able to retain its usefulness,
even in the event of fire eg brick wall. AS1940-2004 clause 5.8.3 gives
a detailed description of the rules relating to the construction of
a bund. Clause
5.8.1 says a bund is not required if your tank fits within the definition
of minor storage.
