Section 38
Section 38
Cast-iron underfired vulcanisers
(1)
Every cast-iron underfired vulcaniser and all its fittings and attachments shall be of good construction, sound material, adequate strength and free from patent defects, and shall be properly maintained.
(2)
Every cast-iron underfired vulcaniser shall have attached to it —
a suitable safety valve (separate from and incapable of being isolated by any stop-valve), which shall be so adjusted as to prevent the vulcaniser from being worked at a pressure greater than the maximum permissible working pressure and which shall be fixed directly to or as close as practicable to the vulcaniser;
a correct steam pressure gauge connected to the steam space and easily visible, which shall indicate the pressure of steam in the vulcaniser or have marked upon it, in a distinctive colour, the maximum permissible working pressure;
a water gauge, of transparent material or other type approved by the Chief Inspector, to show the water level in the vulcaniser, and if the gauge is of the glass tubular type and the working pressure in the vulcaniser normally exceeds 275 kilo-newtons per square metre, the gauge shall be provided with an efficient guard, but not so as to obstruct the reading of the gauge;
where there are two or more vulcanisers in use in the same premises, a plate bearing a distinctive number which shall be easily visible.
(3)
The working pressure of a cast-iron underfired vulcaniser shall not exceed 413 kilo-newtons per square metre.
(4)
No cast-iron underfired vulcaniser shall be used to supply steam to another vulcaniser or other receiver external to the vulcaniser.
(5)
Every cast-iron underfired vulcaniser and all its fittings and attachments shall be thoroughly examined by an authorised boiler inspector at least once in every 12 months, and also after any extensive repairs except that the authorised boiler inspector may, at his discretion, arrange to make the examination up to one month after the 12 months have expired.
(6)
Any examination in accordance with the requirements of subsection (5) shall consist, in the first place, of an examination of the vulcaniser when it is cold, and secondly, of an examination under normal steam pressure; the examination under normal steam pressure shall be made as soon as possible after the examination of the vulcaniser when cold, and the person making the examination shall see that the safety valve is so adjusted as to prevent the vulcaniser from being worked at a pressure greater than the maximum permissible working pressure.
(7)
A report of the result of every such examination in the prescribed form shall, as soon as practicable and in any case within 7 days of the completion of the examination, be prepared in duplicate and signed by the person making the examination. One copy of the report shall be handed to the occupier of the factory and the other copy shall be sent to the Chief Inspector.
(8)
No cast-iron underfired vulcaniser 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 (5) to (7); and no new cast-iron underfired vulcaniser shall be taken into use unless there has been obtained from the Chief Inspector a certificate specifying the maximum permissible working pressure of the vulcaniser and stating the nature of the tests to which the vulcaniser and fittings have been submitted, and the certificate is kept available for inspection, and the vulcaniser is so marked as to enable it to be identified as the vulcaniser to which the certificate relates.
(9)
Where the report of any examination under this section specifies conditions for securing the safe working of a cast-iron underfired vulcaniser, the vulcaniser shall not be used except in accordance with those conditions, and in no case shall the maximum permissible working pressure exceed 413 kilo-newtons per square metre.
(10)
Any person who for the purposes of this section desires that an examination of a cast-iron underfired vulcaniser should be carried out by, and any person who in order to obtain the certificate referred to in subsection (8) 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 that 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.
