| (Cap 56, section 65) [1 March 1963] (G.N.A. 101 of 1962) Cap 56A reg 1 Citation PART I GENERAL These regulations may be cited as the Boilers and Pressure Vessels Regulations. (87 of 1988 s. 41) Cap 56A reg 2 General provisions as to construction, etc. of boilers, etc. Without prejudice to any other provisions of these regulations, every boiler and pressure vessel, every part of a boiler or pressure vessel and every part of the auxiliary equipment connected with a boiler or pressure vessel shall be of good construction, sound material, adequate strength and free from any patent defect. (87 of 1988 s. 42) Cap 56A reg 3 Requirements with respect to boilers PART II BOILERS, STEAM RECEIVERS AND AIR RECEIVERS (1) Every boiler, whether separate or one of a range- (a) shall have attached to it- (i) a suitable spring-loaded safety valve, separate from any stop-valve and capable of being sealed, which shall be fixed directly to the boiler and so adjusted as to prevent the boiler being operated at a pressure greater than its maximum permissible working pressure; (ii) a suitable stop-valve connecting the boiler to the system; (87 of 1988 s. 43) (iii) a correct pressure gauge, connected to the boiler and easily visible by the boiler attendant, which shall have marked upon it by a red line the maximum permissible working pressure of the boiler and which shall indicate the pressure in the boiler in pascals or multiples of pascals; (87 of 1988 s. 43) (iv) at least one water gauge of transparent material, or of such other type as the Authority may approve, to show the water level in the boiler, which shall, if it is of the glass tubular type, be provided with an efficient guard that does not obstruct the reading of the gauge; and (87 of 1988 s. 51) (v) where it is one of 2 or more boilers, a plate bearing a distinguishing number, which shall be easily visible;(b) shall be provided with means for attaching a test pressure gauge; and (c) unless it is externally fired, shall be provided with a suitable fusible plug or an efficient low-water alarm device.(2) Subregulation (1)(a)(ii) shall not apply with respect to economizers. (3) Subregulation (1)(a)(iii), (iv) and (v), (b) and (c) shall not apply with respect to economizers or superheaters. (4) Subregulation (1)(a)(iv) and (c) shall not apply to vessels in which oil is heated at a pressure greater than atmospheric pressure. (87 of 1988 s. 43) Cap 56A reg 4 Requirements with respect to steam receivers (1) Every steam receiver that is not so constructed and maintained as to withstand with safety the maximum permissible working pressure of the boiler to which it is connected or the maximum pressure that can be obtained in the pipe connecting the steam receiver with any other source of supply of steam shall be fitted with- (a) a suitable reducing valve or other suitable automatic appliance to prevent the maximum permissible working pressure of the steam receiver being exceeded; (b) a suitable spring-loaded safety valve that is capable of being sealed and is so adjusted as to permit the steam to escape as soon as the maximum permissible working pressure of the steam receiver is exceeded or a suitable appliance for cutting off automatically the supply of steam as soon as that pressure is exceeded; (c) a correct steam pressure gauge, which shall have marked on it by a red line the maximum permissible working pressure of the steam receiver and which shall indicate the pressure of steam in the steam receiver in pascals or multiples of pascals; (87 of 1988 s. 44) (d) a suitable stop-valve; and (e) where it is one of 2 or more steam receivers, a plate bearing a distinguishing number, which shall be easily visible.(2) The safety valve and the steam pressure gauge of every steam receiver shall be fitted on the steam receiver or on the supply pipe between the steam receiver and the reducing valve or other appliance provided to prevent the maximum permissible working pressure of the steam receiver being exceeded. (3) Every steam receiver shall be provided with means for attaching a test pressure gauge. (4) For the purposes of subregulation (1), other than the provisions of paragraph (e) thereof, any set of steam receivers supplied with steam through a single pipe and forming part of a single machine may be treated as one steam receiver, and, for the purposes of the said subregulation (1), other than the provisions of paragraphs (d) and (e) thereof, any other set of steam receivers supplied with steam through a single pipe may be treated as one steam receiver: Provided that this subregulation shall not apply to any such set of steam receivers unless the reducing valve or other appliance provided to prevent the maximum permissible working pressure of the steam receiver being exceeded is fitted on the said single pipe. Cap 56A reg 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; |
