58. Steam receivers and steam containers (1) Every steam receiver and every part thereof and all its fittings shall be of good construction, sound material, adequate strength and free from patent defect, and shall be properly maintained. (2) Every steam receiver, not so constructed and maintained as to withstand with safety the maximum permissible working pressure of the boiler or the maximum pressure which can be obtained in the pipe connecting the receiver with any source of supply, shall be fitted with— (a) a suitable reducing valve or other suitable automatic appliance to prevent the safe working pressure of the receiver being exceeded; (b) a suitable safety valve so adjusted as to permit the steam to escape as soon as the safe working pressure is exceeded, or a suitable appliance for cutting off automatically the steam supply as soon as the safe working pressure is exceeded; O2 – 41 [Issue 1] Occupational Safety and Health Act (c) a correct steam pressure gauge, which shall indicate the pressure of steam in the receiver; (d) a suitable stop-valve; and (e) except where only one steam receiver is in use, a plate bearing a distinctive number which shall be easily visible. (3) The safety valve and pressure gauge specified in subsection (2) shall be fitted either on the steam receiver or on the supply pipe between the receiver and the reducing valve or other appliance to prevent the safe working pressure being exceeded. (4) For the purpose of subsection (2) other than paragraph (e) thereof, any set of receivers supplied with steam through a single pipe and forming part of a single machine may be treated as one receiver, and for the purpose of the said subsection, except paragraphs (d) and (e) thereof, any other set of receivers supplied with steam through a single pipe may be treated as one receiver but this subsection shall not apply to any such set of receivers unless the reducing valve or other appliance to prevent the safe working pressure being exceeded is fitted on the said single pipe. (5) Every steam receiver and all its fittings shall be properly examined by a registered boiler inspector, so far as the construction of the receiver permits, at least once every 24 months. (6) The original report of the result of every such examination in the form set out in the Seventh Schedule shall be sent by the owner to the Director, Occupational Safety and Health within 28 days of the completion of the examination. (7) Every steam container shall be so maintained as to secure that the outlet is at all times kept open and free from obstruction.
