ABSTRACT A vehicle for transporting a liquid commodity has a combined frangible disc safety vent and siphon unloading pipe nozzle. The siphon unloading pipe passes through a hole in the vehicle that is surrounded by the nozzle side wall. The hole is dimensioned to enable the nozzle to act as a surge chamber that dissipates transient pressure surges and thereby prevents premature breaking of the frangible safety vent disc.
