BOILERS AND PRESSURE RECEIVERS ORDINANCE, 1%2
(No. 38 of 1962).
BOILERS AND PRESSURE Receivers REGULATIONS, 1962.
In exercise of the powers conferred by section 65 of the Boilers and Pressure Receivers Ordinance, 1962, the Governor in Council bas made the following regulations-
PART I
GENERAL.
1. These regulations may be cited as the Boilers and Pressure Receivers Regulations, 1962 and shall come into operation on the day appointed for the commencemeat of the Boilers and Pressure Receives Ordinance, 1962.
1. Without prejudice to any other provisions of these regulations, every boiler and pressure receiver, every part of a boiler or pressure receiver and every part of the auxiliary equipment connected with a boiler or pressure receiver shall be of good construction, sound material. adequate strength and free from any patent defect.

PART II
BOILERS, STEAM RECEIVERS AND AIR RECEIVERS.
(1) Every boiler, whether separate or one of a range- (a) shall have attached to it-
(D) 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 permis. sible working pressure:
(ii) a suitable stop-valve connecting the boiler to the steam pipe;
(iii) a correct steam pressure gauge, connected to the steam space and easily visible by the boiler attendant, which shall indicate the pressure of steam in the boiler in pounds per square inch and have marked upon it by a red line the maximum permissible working pressure of the boiler;
(iv) at least one water gauge of transparent material, or of such other type as the Principal Surveyor may approve, to show the water level in the boiler, which shall, if it is of the
3
glass tubular type, be provided with an efficient guard that does not obstruot the reading of the gauge; and
(v) where it is one of two 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) Sub-sub-paragraph (ii) of sub-paragraph (a) of paragraph (1) shall not apply with respect to economizers.
(3) Sub-sub-paragraphs (iii), (iv) and (v) of sub-paragraph (a) of paragraph (1) and sub-paragraphs (6) and (c) of paragraph (1) shall not apply with respect to economizers or superheaters.

4. (1) Every steam receiver that is not so constructed and main- Requirements tained as to withstand with safety the maximum permissible working with respect pressure of the boiler to which it is connected or the maximum pressure receivers. 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;
(6) 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 indicate the pressure of steam in the steam receiver in pounds per square inch and have marked on it by a red line the maximum permissible working pressure of the steam receiver;
(d) a suitable stop-valve; and
(e) where it is ous of two 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 attach- ing a test pressure gauge.
