Regulation 28

of good construction, sound material and adequate strength;

free from patent defects; and

properly maintained.

shall have attached to it —

a suitable safety valve which is —

separate from and incapable of being isolated by any stop-valve;

adjusted so as to prevent the boiler from being worked at a pressure greater than the safe working pressure; and

fixed directly, or as close as practicable, to the boiler;

a suitable stop-valve connecting the boiler to the steam pipe;

a correct steam pressure gauge, connected to the steam space and easily visible by the boiler attendant, which —

indicates the pressure of steam in the boiler; and

is marked, in a distinctive colour, with the safe working pressure;

at least one water gauge of transparent material or any other type approved by the Commissioner thereof which —

shows the water level in the boiler; and

if the gauge is of the glass tubular type and the working pressure in the boiler normally exceeds 275 kilo-newtons per square metre, is provided with an efficient guard that does not obstruct the reading of the gauge; and

where it is one of 2 or more boilers, a plate bearing a distinctive number which shall be easily visible;

shall be provided with means for attaching a test pressure gauge; and

shall be provided with —

a suitable fusible plug; or

an efficient low-water alarm device.

which uses electricity as the only form of power;

which has a maximum steam volume of not more than 40 litres and a safe working pressure of not more than 4 bars; and

into which water is fed manually at the start of the steam generation process and cannot be fed continuously from a potable water main.

steam boiler referred to in paragraph (5), including all its fittings and attachments, shall be thoroughly examined by an authorised examiner at least once every 2 years and also after any extensive repair; and

surface of the external shell of a steam boiler referred to in paragraph (5) shall be examined by an authorised examiner at least once every 6 years, and for the purpose of such examination, the insulation on the shell shall be removed completely.

have attached to it a steam pressure control device which shall be set to the pressure at or below the maximum permissible working pressure of the boiler; and

have a safety valve attached to the boiler which shall be examined and tested by a competent person at least once a month, and the report on every such test shall be recorded and shall be made available for inspection at any time by an inspector.

unless all inlets through which steam or hot water might otherwise enter the boiler from any other part of the range are disconnected from the part; or

unless —

all valves or taps controlling such steam and hot water entry are closed and securely locked; and

where the boiler has a blow-off pipe in common with one or more other boilers or which delivers into a common blow-off vessel or sump, the blow-off valve or tap on each such boiler is so constructed that it can only be opened by a key which —

cannot be removed until the valve or tap is closed; and

is the only key in use for that set of blow-off valves or taps; and

until the particular boiler has been sufficiently cooled to make it safe for the person entering or being in the particular boiler.

at least once every year; and

after any extensive repairs.

of an examination of the boiler when it is cold and the interior and exterior have been prepared in the manner specified by the Commissioner; and

except in the case of an economiser or a superheater, of an examination when it is under normal steam pressure which —

must be made as soon as possible after the examination of the boiler when cold; and

must include an examination to determine whether the safety valve is so adjusted as to prevent the boiler from being worked at a pressure greater than the safe working pressure, unless prior written permission has been obtained from the Commissioner.

issue and sign a report, in a form determined by the Commissioner, of the result of the examination referred to in paragraph (12);

provide a copy of the report referred to in sub-paragraph (a) to the owner of the steam boiler;

inform the Commissioner —

as soon as is reasonably practicable, if the examination shows that the steam boiler cannot continue to be used safely unless repairs are carried out; or

in any other case, within 28 days of the completion of the examination, of the results of the examination in a manner acceptable to the Commissioner; and

exercise all due diligence in making any report or in conducting any examination of any steam boiler under this regulation.

any steam boiler with a maximum permissible working pressure not exceeding 0.5 bar; and

any steam boiler referred to in paragraph (5).
