Distances To Boundary Fences

Guide for Separation Distances from Tanks to Buildings

For diesel the width of tank or diameter which ever are greater dimension or at least 3 Metres to boundary fences. AS 1940-2017 Table 5.3 For flammable liquids at least 6 Metres but further distance may be required – As a guide refer to separation distances to buildings for petrol above 7,000 Litres capacity. AS 1940-2017 Table 5.3 and Table 5.4 Poly diesel tanks can be used up to maximum capacity of 10,000 Litres but must have minimum separation distance from buildings or boundary fences of 15 Mtrs. AS 1940-2017 2.2.5.2 (a & e )

Further Info On Storage Tanks

Separation distance between horizontal tanks when installed together is a minimum of 600mm between such tanks but increases to at least 1 Meter for vertical tanks. AS 1940-2017 5.7.5 and 5.7.6 Tanks for combustible liquids can be stored inside buildings up to a maximum size of 1000 Litres. See further criteria to be met AS 1940-2017 5.6.3.1 Polyethylene diesel storage tanks must not be used on construction sites. AS 1940-2017 2.2.6 A minimum 3 Metre separation is required from a flammable self-bunded tank to any ignition source including the vehicle being refilled. AS 1940-2017 5.9.2 ( g ) Further regulations governing pumping equipment, dispensing points and ignition sources to storage tanks needs to be followed and can be found in AS 1940:2017
