To exempt marine fuel dispensing stations from the application of Clause 4.6.5.2.(2)(b), which would otherwise require automatic hose nozzle valves, if certain conditions are met [dispensing operations must be continuously attended and hose nozzle valves are manually operated], on the basis that marine fuel dispensing stations pose a higher fire risk.
The conditions [that are to be met] are to limit the probability that inadequate control of dispensing operations will lead to an unwanted escape of liquid, which could lead to the ignition of vapour from a nearby ignition source, which could lead to harm to persons.
To state the application of Clause 4.6.5.2.(2)(a).
