-
Vent terminals for underground flammable liquid (e.g. petroleum) tanks have a flame arrester fitted Note: Flame arrester may also satisfy the protective cage requirement below
-
There are no combustible materials (e.g. wood chips, dry leaves, rubbish) within 3 m of the vent pipes
-

Dispensers
-
Emergency stop on each dispenser is regularly tested (e.g. monthly) for compliant operation
-
Hoses are free of cracks, fractures, leakage, or movement between hose and fittings
-
Impact protection is installed (e.g. bollards) or dispenser is located so potential damage (e.g. from vehicles) is minimised

LIGHTING
-
Areas around the dispensers and payment unit are sufficiently lit to provide a safe working environment whenever the unit is available for service

An emergency information panel (EIP) placard is posted on above-ground tanks or at tank storage areas
-
There is a sign at the above-ground tank or tank storage area showing either standard warning symbols of at least 100 mm diameter or words saying ‘FLAMMABLE GAS’ and ‘NO SMOKING’, or a warning sign (in lettering of at least 50 mm high) prohibiting smoking and ignition sources If the area is isolated by a fence, the signs must be visible from outside the fence and all points of access
-
Each activation point for the emergency shut-down system has a sign with instructions (in red or dark lettering at least 20 mm high on a white background) on how to activate the system Note: The instructions may be given on same sign as ‘LP GAS EMERGENCY STOP’
-
Tanks are at least 6 m from any other above-ground tank, package store or filling area for flammable or combustible materials
-
Tanks are at least 2 m from any vent outlet of a flammable liquid store (e.g. vents for underground tanks)
-
Tank impact protection is at least equivalent to highway crash barriers (i.e. 700 mm high and at least 1.5 m from the tank
-
There are no combustible materials within 3 m of the LP Gas tanks
-
The site has a clear exit for fuel tankers so vehicles leave by driving forward without needing to reverse
-
Tanks that are no longer in service have been decommissioned and gas-freed
-
For single tanks with a capacity of 8 kL or less, there must be access to a tap with sufficient water pressure to operate a garden hose
-
Hose reels are installed near all tanks with capacities greater than 8 kL Note: Fire extinguishers of type 2A 60B(E) may be substituted for hose reels where there is a single tank with a capacity of 16 kL or less and the water supply is insufficient
-
There are enough hose reels to ensure that water hose nozzles can reach everywhere within 5 m of the tank and tanker standing area
-
The ground below tanks and for at least 1.5 m beyond each tank is either paved or resistant to saturation by flammable liquids
LP Gas Vehicle Filling
-
Communication system is available so attendant can speak to anyone using the LP Gas dispenser
-
Two spare standard metal automotive filler caps (spare fuel caps) are kept on site in case the vehicle fill point leaks
-
Signs with standard warning symbols of at least 100 mm diameter or words saying ‘STOP ENGINE – NO SMOKING’ (in red or dark lettering at least 50 mm high on a white background) are displayed at or adjacent to the filling area
-
Driver instruction signs are displayed in a readily visible location at each LP Gas dispenser (see Figure 5)
-
Dispensers have signs with LP Gas filling instructions (see Figure 6)
-
A sign with the LP Gas emergency procedure is readily visible outside the service station building and another sign with the procedure is prominently displayed inside the building or office
-
Hoses are free of cracks, fractures, leakage, or movement between hose and fittings, and are inspected at least monthly
-
Fuel is not released when the unconnected (i.e. not attached to a vehicle fill point) nozzle trigger is operated
-
For dispensers that are open to the public, the nozzle can be locked to the dispenser when the unit is not available for operation
-
Self-service dispensers are supervised from a control centre (console) by an attendant who is specifically in charge of fuel dispensing
