5. Requirements with respect to air receivers
(1) Every air receiver shall—
(a) where the air receiver is connected with a compressor, be so constructed as to withstand with safety the maximum pressure that can be obtained in the compressor or be fitted with a suitable reducing valve or other suitable appliance to prevent the maximum permissible working pressure of the air receiver being exceeded;
(b) be fitted with a suitable spring-loaded safety valve that is so adjusted as to permit the air to escape as soon as the maximum permissible working pressure of the air receiver is exceeded;
(c) be fitted with a correct pressure gauge, which shall indicate the pressure of air in the air receiver in pascals or multiples of pascals; (87 of 1988 s. 45)
(d) be fitted with a suitable appliance for draining the air receiver;
(e) be provided with a suitable manhole, handhole or other means that will allow the interior thereof to be thoroughly cleaned; and
(f) where more than one air receiver is being used by the same person in any industrial undertaking, bear a distinguishing mark, which shall be easily visible.
(2) Every air receiver, other than a pressurized fuel container, shall have marked upon it so as to be plainly visible the maximum permissible working pressure of the air receiver and the date on which it was last examined by an appointed examiner. (87 of 1988 s. 45)
(3) Where the safety valve fitted on an air receiver in accordance with subregulation (1)(b) is not fitted directly to the air receiver, a suitable fusible plug shall also be fitted to the air receiver.
(4) For the purposes of those provisions of subregulations (1) and (3) that relate to safety valves and pressure gauges, any set of air receivers supplied with air through a single pipe may be treated as one air receiver:
Provided that, where, by virtue of the said subregulation (1), the air receiver is required to be fitted with a reducing valve or other appliance to prevent the maximum permissible working pressure of the air receiver being exceeded, this subregulation shall not apply unless such valve or other appliance is fitted on the said single pipe.

6. Special requirements with respect to pressurized fuel containers
(1) Every pressurized fuel container shall—
(a) be fitted with a pressure release valve;
(b) be placed in a metal tray or housed in a suitable structure so that all valves and safety devices are readily accessible;
(c) where it has a maximum permissible working pressure of not more than 500 kilopascals, be fitted with piping properly secured along its whole length, save that for a length of 600 millimetres immediately preceding the burner the piping shall be in the form of a loose coil so as to facilitate easy manipulation; and (L.N. 107 of 1979)
(d) be fitted with a remote control valve situated in a position as near to the burner as is possible consistently with its safe operation.
(2) The provisions of subregulation (1) shall apply to pressurized fuel containers in addition to any of the provisions of regulation 5 that apply to such containers.
(87 of 1988 s. 46)

7. Pumps
Every pump used in connection with the fuel burning system in a fuel burning installation, whether the pump is used for the purpose of supplying the burners or of transferring fuel, shall be separated from any pump used for any other purpose and shall be provided with—
(a) an efficient escape valve, which shall discharge into the suction side of the pump; and
(b) means for stopping the pump, which shall be situated outside the boiler house in a readily access position.

8. Heaters
(1) No means, other than steam or such other means as may be approved by the Authority, shall be used for heating fuel in a fuel burning installation. (87 of 1988 s. 51)
(2) Every heater fitted in a fuel burning installation shall be of good design and adequate strength.
(3) Where, in any such heater, steam is used to heat the fuel and the condensate is returned to the boiler in connection with which the heater is provided, the heater shall be provided with an observation tank by means of which it can be readily ascertained whether or not the condensate is free from oil.

9. Pumps, etc. to be fitted with equipment to catch any leakage of fuel
Every pump, heater, strainer and furnace mouth in a fuel burning installation shall be fitted with save-alls or gutters for the purpose of catching any fuel that may leak therefrom or that may spill when any cover or door is open or of intercepting any fuel that may escape from the burners, as the case may be.

10. Multiple burners
(1) (a) Where there is more than one burner in a fuel burning installation, a master valve shall be provided for the purpose of enabling the supply of fuel to every burner to be shut off in the event of an emergency.
(b) Every such master valve shall—
(i) be situated outside the boiler house in a readily accessible position; and
(ii) be of the quick-closing type.
(2) The shut-off valves on the furnace front that control the supply of fuel to such burners shall be provided with safety catches so as to prevent any such burner from being removed until the supply of fuel is shut off.

11. Flue dampers
(1) Every flue damper fitted in a fuel burning installation shall be so constructed that it can be fixed securely in an open position.
(2) Save as provided in subregulation (3), the area of any such flue damper shall be such that it does not obstruct more than 90% of the free space of the flue.
(3) Where any such flue damper does not comply with subregulation (2), the flue damper shall be interlocked with the fuel supply or otherwise so arranged that the fuel burning installation cannot be started up or operated when the flue is closed.

12. Steam pipes and water pipes to be protected against weather, etc.
Every pipe that conveys oil, steam or water under pressure to or from a boiler, steam receiver or steam container shall be protected to the satisfaction of the Authority against the effect of weather and damp and against external damage.
(87 of 1988 ss. 47 & 51)

13. Steam pipes to be lagged
Every pipe that conveys oil or steam under pressure shall be lagged to the satisfaction of the Authority with fire-proof material.
(87 of 1988 ss. 48 & 51)
