THE GAS CYLINDERS (CONVEYANCE) REGULATIONS, 1931, DATED JULY 31, 1931, MADE BY THE SECRETARY OF STATE FOR THE HOME DEPARTMENT IN PURSUANCE OF SECTION 6 OF THE PETROLEUM (CONSOLIDATION) ACT, 1928 (18 & 19 GEO. 5 C. 32) AS APPLIED BY ORDER IN COUNCIL, DATED THE 20TH JANUARY, 1930. (a)[These Regulations (S.R. & O. 1931, p. 1040) are printed as amended by Regulations, dated July 24, 1947 (S.R. & O. 1947 (No. 1594) I, p. 1681).]
In pursuance of Section 6 of the Petroleum (Consolidation) Act, 1928, as applied by Order in Council dated the 20th January, 1930, I hereby make the following Regulations for the conveyance by road of vessels containing any of the gases specified in the First Schedule hereto in a compressed state.
1. No cylinder shall be used for the conveyance by road of any of the said gases in a compressed state unless (1) it is constructed in accordance with the specifications contained, and has complied with the tests described, in the Second Schedule hereto; (2) the conditions contained in the following Regulations are complied with.
2. Cylinders shall be maintained in good condition and the valves shall be securely closed so as to prevent leakage.
3. Cylinders shall be so conveyed as not to project beyond the sides or ends of the vehicle. Adequate means shall be taken to prevent cylinders falling off the vehicle. This regulation shall not apply to any cylinder containing any of the gases specified in the First Schedule in a compressed state carried exclusively for the purposes of, and attached to, the vehicle.
4. Cylinders shall be legibly marked or labelled with the name of the gas and the name and address of the person or firm by whom it was compressed.
5. The working or internal pressure in any cylinder shall not exceed 1,980 lbs. to the square inch.(b)
6. The valves of cylinders containing carbon monoxide, coal gas, hydrogen or methane shall be protected against damage, either by the design of the cylinder or by the provision of a stout metal cap or metal cover, securely attached to the body of the cylinder. The metal cap or cover shall be so made that it is nowhere in actual contact with any part of the valve or valve body. Every valve cap or cover shall be provided with a vent of such size as to prevent any gas pressure inside the cap or cover. This Regulation shall not come into force until after a period of one year from the date of these Regulations.
(a) S.R. & O. 1930 No. 34 p. 4 above.
(b) Regulation 5 as amended by S.R. & O. 1947 No. 1594.
7. The valves of cylinders containing carbon monoxide, coal gas, hydrogen or methane shall be provided with left handed screw threads for the pipe or other connections.(a)
8. Oil or similar lubricant shall not be used on any valves or other fittings of any cylinder.
9. Each cylinder shall, before being filled with gas, have been submitted by the gas compressing person or firm within the preceding two years to the hydraulic test specified in the Second Schedule. Prior to any hydraulic 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, prior to the hydraulic test, shall be heated to a temperature not exceeding 300° C. and again cleaned and examined. After each hydraulic test and before being taken into use the cylinder shall be thoroughly dried internally, and shall be stamped on the neck end with marks and figures indicating the person or firm and the date of test as specified in Clause 8 of the Second Schedule. Any cylinder which fails to pass the test shall not be conveyed by road when containing any compressed gas to which these Regulations apply.
10. Cylinders containing gases shall be painted with the following identification colours:—
Air … … … … … … … … … … … grey
Argon … … … … … … … … … … . blue
