[1988 Ed.
[Subsidiary]
(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.
Requirements with respect to air receivers
5. (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:
