PART 1

ROAD TANKERS

1. In this Part, unless the context otherwise requires-
"compression ignition engine" (壓燃式引擎) means a compression ignition engine within the meaning of the Road Traffic (Construction and Maintenance of Vehicles) Regulations (Cap 374 sub. leg. A);
"overall height" (總高度) means overall height within the meaning of the Road Traffic (Construction and Maintenance of Vehicles) Regulations (Cap 374 sub. leg. A);
"vessel" (盛器), in relation to a road tanker, means that part of the tanker which is used to contain liquefied petroleum gas in bulk.

2. All equipment of the road tanker shall be in good and efficient working order and in such condition as not to be likely to cause danger to any person upon the tanker or upon a road.

3. The body, chassis and fuel tank of the road tanker and all equipment shall be constructed of non-combustible material.

4. Any combustible material used in the construction of the road tanker shall be flame-resistant.

5. The road tanker shall he not more than 4.1 metres in overall height.

6. The vessel of the road tanker shall-
        (a) be of a design pressure which includes an allowance to accommodate stress due to horizontal and vertical acceleration and retardation likely to be encountered in operation;
        (b) where the vessel has a water capacity of more than 5000 litres, be fitted with baffle plates designed, so far as is practicable, to minimize surge and to allow for complete internal examination of the vessel;
        (c) be mounted on the tanker in a sound manner;
        (d) be effectively screened with fire-resisting shields from-
          (i) the interior of the cab;

7. All valves, fittings, pumps, pipework and accessories fitted to the road tanker shall be so situated or protected that the risk of damage or leakage of liquefied petroleum gas in the event of the tanker being involved in a traffic accident is, so far as is practicable, minimized.

8. Any section of a pipe or hose of the road tanker which may-
        (a) contain liquid liquefied petroleum gas; and
        (b) be closed at each end,
shall be provided with hydrostatic relief valves to protect that section from bursting due to increase of hydraulic pressure caused by temperature rise likely to be encountered in operation.

9. The engine of the road tanker shall be-
        (a) a compression-ignition engine;
        (b) provided with an air inlet system which prevents-
          (i) over-running of the engine to destruction; and
          (ii) flame propagation due to engine back-fire; and
        (c) constructed and so situated or protected so as to avoid any danger to any liquefied petroleum gas carried by the tanker.

10. The fuel tank of the road tanker shall be-
        (a) of double case construction;
        (b) fitted with a lock to the filling hole cover;
        (c) so placed that, in the event of a leak from the tank, fuel can only drain to the ground;
        (d) separated from the cab of the tanker; and
        (e) suitably protected against impact.

11. A means of-
        (a) cutting off the supply of fuel to the engine of the road tanker; and
        (b) stopping that engine,
shall be provided in a position which is-
        (i) outside the cab of the tanker;
        (ii) easily accessible; and
        (iii) identified, in the English and Chinese languages, by a notice prominently and legibly stating-
"EMERGENCY ENGINE STOP
緊急停車掣".

12. All electrical apparatus in the road tanker shall be so constructed and installed as to guard adequately against the risk of short circuit and the outbreak of fire.

13. All electrical apparatus which is in any enclosed area of the road tanker where an accumulation of liquefied petroleum gas may occur shall be suitable for use Zone 1 areas as defined in British Standard Code of Practice 5345: Part 2: 1983.

14. All electrical apparatus which is not in any enclosed area of the road tanker but is not more than 750 millimetres distant from the vessel of the tanker, or any pressure valve, fixed liquid level gauge, vapour return connection, loading or draw-off connection, or other opening to the vessel, shall be suitable for use in Zone 2 areas as defined in British Standard Code of Practice 5345: Part 2: 1983.

15. The road tanker shall be fitted with-
        (a) no tyres other than anti-static tyres each of which has an electrical resistance which complies with British Standard 2050; or
        (b) an anti-static chain so that one end of the chain is effectively secured to the chassis of the tanker and the other end of the chain touches the ground.

16. The road tanker shall prominently and legibly display, in the English and Chinese languages, in letters and characters not less than 120 millimetres in height, the following notices-
        (a) at the front end of the tanker-
"CAUTION LPG
小心石油氣";
        (b) at the rear end of the tanker-
"CAUTION LPG-KEEP CLEAR
小心石油氣─不得駛近"; and
        (c) at each side of the tanker-

"CAUTION LPG-NO SMOKING
小心石油氣─不准吸煙".

17. The name and telephone number of the person to be contacted in the event of an emergency involving the road tanker shall be prominently and legibly displayed in the English and Chinese languages on each door of the cab of the tanker.
