Section 37
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 suitable reducing valve or other suitable automatic appliance to prevent the safe working pressure of the receiver being exceeded;
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 supply of steam as soon as the safe working pressure is exceeded;
a correct steam pressure gauge, which shall indicate the pressure of steam in the receiver;
a suitable stop-valve; and
except where only one steam receiver is in use, a plate bearing a distinctive number which shall be easily visible,and the safety valve and pressure gauge 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.
(3)
For the purpose of subsection (2), except 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 that 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 that single pipe.
(4)
Every steam receiver and all its fittings shall be thoroughly examined by an authorised boiler inspector, so far as the construction of the receiver permits, at least once in every 24 months.
(5)
The Chief Inspector may, if he thinks fit, by a certificate in writing authorise, subject to any conditions specified in the certificate, a period exceeding 24 months within which the examination under subsection (4) is to be made.
(6)
A report of the result of every such examination in the prescribed form and containing the prescribed particulars (including particulars of the safe working pressure), shall be prepared in duplicate and signed by the person making the examination. A copy of such report shall be handed to the occupier of the factory and the other copy shall be sent to the Chief Inspector.
(7)
No steam receiver which has previously been used shall be taken into use in any factory for the first time in that factory until it has been examined and reported on in accordance with subsections (4) and (6); and no new steam receiver shall be taken into use unless there has been obtained from the Chief Inspector a certificate specifying the safe working pressure of the receiver and stating the nature of the tests to which the receiver and fittings have been submitted, and the certificate is kept available for inspection, and the receiver is so marked as to enable it to be identified as the receiver to which the certificate relates.
(8)
Any person who for the purposes of this section desires that an examination of a steam receiver should be carried out by, and any person who in order to obtain the certificate referred to in subsection (7) desires that the necessary tests should be carried out by, any authorised boiler inspector who is an inspector, shall notify the Chief Inspector accordingly and, on payment by such person of the prescribed fee, the Chief Inspector shall instruct such an authorised boiler inspector to carry out the examination or the tests, as the case may be.
(9)
Every steam container shall be so maintained as to secure that the outlet is at all times kept open and free from obstruction.
