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, and to the fuel depot. The size rules in this article do not apply if you are transporting diesel. Diesel is not classed as a C1 flammable liquid if it is being transported! 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.
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.
