142 Vapour transfer system and lines
142 Vapour transfer system and lines
(1) A petrol storage tank must have a vapour transfer system that ensures vapour displaced by the transfer of petrol to the petrol storage tank from a delivery tank on a tanker truck is returned to the delivery tank by a vapour return line.
(2) The vapour return line must not permit the escape of vapour into the atmosphere.
(3) The vapour return line must have a fitting on the vapour return line that—
(a) connects to the vapour return line on the delivery tank on the tanker truck, and
(b) does not permit the escape of vapour into the atmosphere, and
(c) closes automatically when disconnected.
(4) The fitting on the vapour return line must be incompatible with the fitting on the petrol delivery line to ensure liquid is not discharged into the vapour return line.
