(1)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 other source of supply, shall be fitted with—
(a)a suitable reducing valve or other suitable automatic appliance to prevent the safe working pressure being exceeded; and
(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 supply of steam as soon as the safe working pressure is exceeded; and
(c)a correct steam pressure gauge, which must indicate the pressure of steam in the receiver . . . F2; and
(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.
(2)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)Where any set of receivers is supplied with steam through a single pipe and the reducing valve or other appliance required by paragraph (a) of subsection (1) of this section is fitted on that pipe, the set shall be treated as one receiver for the purposes of paragraphs (a) to (c) of subsection (1) and for the purposes of subsection (2) of this section, and if the set forms part of a single machine, also for the purposes of paragraph (d) of the said subsection (1).
(4)Every part of every steam receiver shall be of good construction, sound material, adequate strength and free from patent defect.
(5)Every steam receiver and its fittings shall be properly maintained, and shall be throughly examined by a competent person, so far as the construction of the receiver permits, at least once in every period of twenty-six months.
(6)A report of the result of every such examination containing the prescribed particulars (including particulars of the safe working pressure) shall be entered in or attached to the general register.
(7)Every steam container shall be so maintained as to secure that the outlet is at all times kept open and free from obstruction.
(8)In this section—
“safe working pressure” means, in the case of a new steam receiver, that specified by the maker, and in the case of a steam receiver which has been examined in accordance with the provisions of this section, that specified in the report of the last examination;
“steam receiver” means any vessel or apparatus (other than a steam boiler, steam container, a steam pipe or coil, or a part of a prime mover) used for containing steam under pressure greater than atmospheric pressure;
“steam container” means any vessel (other than a steam pipe or coil) constructed with a permanent outlet into the atmosphere or into a space where the pressure does not exceed atmospheric pressure, and through which steam is passed at atmospheric pressure or at approximately that pressure for the purpose of heating, boiling, drying, evaporating or other similar purpose.]
