THE COMPRESSED GAS CYLINDERS (FUEL FOR MOTOR VEHICLES) REGULATIONS, 1940, DATED NOVEMBER 18,1940, MADE BY THE SECRETARY OF STATE FOR THE HOME DEPARTMENT UNDER SECTION 6 OF THE PETRO-LEUM (CONSOLIDATION) ACT, 1928 (18 & 19 GEO. 5 C.32), AS APPLIED BY ORDER IN COUNCIL, DATED JANUARY 20, 1930.In pursuance of the powers conferred on me by section 6 of the Petroleum (Consolidation) Act, 1928, as applied by Order in Council dated the 20th January, 1930(a), I hereby make the following Regulations for the conveyance by road of cylinders (other than cylinders which comply with the Gas Cylinders (Conveyance) Regulations 1931(b)), which (i) contain any of the gases specified in the First Schedule to these Regulations in a compressed state, and (ii) during conveyance are fitted to a motor

(b) S.R. & O. 1931 No. 679, p. 16 above.
vehicle or a trailer and intended for the storage of compressed gas for the purpose of the propulsion of the vehicle to which they are fitted or the drawing vehicle as the case may be.
1. No cylinder to which these Regulations apply shall be used unless—
(i) it has been constructed by a cylinder manufacturer approved in writing by the Secretary of State for the purposes of these Regulations, and
(ii) it has been constructed in accordance with the Specification contained in Part I of the Second Schedule to these Regulations and also with either Specification A or Specification B contained in Part II of that Schedule, and has complied with the tests and other requirements described in those Specifications, the method of manufacture and testing of cylinders of this class at the works of the manufacturer being carried out to the satisfaction of an inspecting authority approved in writing by the Secretary of State for the purposes of these Regulations.
2. Each cylinder valve and other fitting shall be of forged steel, or of brass or bronze complying with the specification contained in the Third Schedule to these Regulations.
3. Each cylinder, or the valve or other fitting of such cylinder, shall be provided either with a fusible plug designed to fuse at 150°C. or with a bursting disc designed to operate at a pressure 1½ times the designed working pressure of the cylinder.
4. Each cylinder and its valves and fittings shall be maintained in good condition.
5. The working or internal pressure in any cylinder shall not exceed that for which the cylinder has been designed, and in any case shall not exceed 3,000 lbs. per square inch for cylinders constructed in accordance with the said Specification A and 1,800 lbs. per square inch for cylinders constructed in accordance with the said Specification B.
6. No cylinder shall be filled with gas unless it has been submitted within the preceding 2 years to the hydraulic stretch test described in the specification contained in Part II of the Second Schedule to these Regulations in accordance with which it was constructed. Prior to any hydraulic stretch test the cylinder shall be thoroughly cleaned and examined externally, and, so far as practicable, internally, for surface defects, corrosion and foreign matter. Where internal rust or foreign matter is observed the cylinder shall, prior to the hydraulic stretch test, be heated to a temperature not exceeding 300°C. and again cleaned and examined. After each hydraulic stretch test and before being taken into use the cylinder shall be thoroughly dried internally and clearly and permanently marked on the neck end with marks and figures indicating the person or firm who made the test and the date of the test as specified in Regulation 9. Any cylinder which fails to pass the test shall not thereafter be used for the conveyance by road of any compressed gas named in the First Schedule to these Regulations, and shall be rendered unserviceable for such use.
7. Except as provided in Regulation 6 and paragraphs 9, 14, 17, 21, 26 and 27 of the Second Schedule to these Regulations, no cylinder after completion of manufacture shall be subjected to any heat treatment process or be mechanically altered in any way.
8. No cylinder shall be filled with any of the gases specified in the First Schedule to these Regulations, unless steps have been taken to ensure that, at the time of filling, the gas is free from hydrogen sulphide and is, as far as is reasonably practicable, free from moisture and organic sulphur impurities.
9. Each cylinder shall be permanently and clearly marked with:—
(a) the manufacturer's identification mark and the rotation number of the cylinder;
(b) the date of the last hydraulic stretch test (this date may be indicated by the month and year, or by the year with a symbol to denote the quarter of the year), and the identification mark of the person or firm who made the test;
(c) a mark indicating the specification in Part II of the Second Schedule to these Regulations, in accordance with which the cylinder was constructed, viz. GP for Specification A, and GPM for Specification B or the corresponding British Standards Institution specification marks.
10. Every cylinder shall be securely attached to the vehicle or trailer on which it is being conveyed.
11. There shall be affixed to every vehicle or trailer on which any cylinder is being conveyed, and maintained in a legible condition, a notice showing as respects each cylinder for the time being conveyed thereon:—
(a) the manufacturer's identification mark and the rotation number of the cylinder;
(b) the water capacity of the cylinder in cubic feet;
(c) the date of manufacture of the cylinder;
(d) the date of the last hydraulic stretch test of the cylinder; and
(e) the working pressure of the cylinder.
12. Each cylinder shall be clearly marked in a distinctive paint with the words "FOR GAS PROPULSION ONLY, WORKING PRESSURE— LBS. PER SQUARE INCH" and with the water capacity in cubic feet. The figure for working pressure shall be that for which the cylinder is designed.
13. Not less than one year after the construction of any batch of cylinders, and subsequently at such intervals, not being less than one year, as the Secretary of State...
