Diesel tanks AS1940 regulations

Does your diesel tank comply with AS1940 Standards?

When handling combustible and flammable liquids complying with safety measures is an important priority across industry. There are strict manufacturing and design requirements within Australia to ensure site compliance and safety, all of which are found within the Australian Standards. For the fuel storage industry, the Australian Standard 1940 is the primary regulation outlining how to safely handle and store flammable liquids. In 2017 major amendments were made to this standard showcasing new safety and operational requirements for fuel sites and diesel tanks. The changes affect the design and manufacturing of fuel tanks, site operations and the maintenance of your diesel fuel tank. It is important therefore that both manufacturers and suppliers are aware of the major changes that impact their current on-site fuel storage solutions and impact future buying decisions

It’s important your diesel tank complies with the AS1940 as this standard provides requirements for the planning, design, construction, and safe operations of all installations in which flammable/combustible liquids are stored or handled. Here are the key areas your fuel tank must comply with:

Additional safety features with bunds

For containment and potential spillage, having a bunded wall is already an important safety feature in case of fuel leakage.  The bund is an important safety feature as it contains any spillage within a secondary outer tank containment. Before the changes to AS1940 the spill containment of the secondary tank was at 100% capacity, with the introduction of the new standards increasing capacity to 110% of the largest tank.

Liquid Tank Levels

The introduction of safe fill levels is now mainstream across fuel tank providers with the AS1940 standard placing the limit of safe fill level to 95% of the tank’s capacity. Also, important to note that for above ground fuel storage tanks storing 5000L+ of a flammable liquid, a high-level alarm is now required as an additional safety feature. This is also applicable for above ground storage tanks storing combustible liquids, except the high-level alarm is required for 25,000l of liquid rather than 5000l.

GHS Alignment
New regulations surrounding chemical classification were also introduced with the amendment with a globally harmonised classification system. This makes fuel storage easier and safer as there is a greater transparency about the specific type of flammable and combustible liquid and its relevant storage containers.

I purchased a Poly Tank Fuel Trailer from DUROTANK in April 2018. DUROTANK builds one of the best fuel trailers I have ever used. The build quality, engineering and attention to detail is unreal. The fuel trailer is rock solid, it tracks extremely well full of fuel at 100km/hr and its road worthy. All of the fittings are hoses are high quality hydraulic hose and crimped fittings so there are no leaks. The Durotank team is very easy to deal with and more than happy to help with any enquiries. The staff are friendly and it is a pleasure to do business with them. I’d buy another one in a heartbeat, that’s for sure


Ben Harris – AB Contract Farming

The Duro Cubes are going extremely well! My guys are very happy with them. Having them already saved us on oil transport on at least 2 occasions so far and has also allowed us to restructure our oil work days and use out of hours oil deliveries to make more efficient use of the time on site.
