FACTORIES ACT (NORTHERN IRELAND) 1965 - SECT 33

Steam boilers attachments and construction.

33.(1) Subject to subsection (3), every steam boiler, whether separate or one
of a range,

(a)shall have attached to it the devices mentioned in subsection (2);

(b)shall be provided with means for attaching a test pressure gauge, and

(c)shall, unless externally fired, be provided with a suitable fusible plug or
an efficient low-water alarm device.

(2) The devices referred to in subsection (1) are

(a)a suitable safety valve, separate from any stop-valve, which shall be so
adjusted as to prevent the boiler being worked at a pressure greater than the
maximum permissible working pressure and shall be fixed directly to, or as
close as practicable to, the boiler;

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

(c)a correct steam pressure gauge connected to the steam space and easily
visible by the boiler attendant, which shall indicate the pressure of steam in
the boiler ..., and have marked on it in a distinctive colour the
maximum permissible working pressure;

(d)at least one water gauge of transparent material or other type approved by
the chief inspector to show the water level in the boiler, together, if the
gauge is of the glass tubular type and the working pressure of the boiler
normally exceeds [2.75 bars], with an efficient guard provided so as not to
obstruct the reading of the gauge;

(e)where the boiler is one of two or more boilers, a plate bearing a
distinctive number which shall be easily visible.

(3) Subsection (2)(b) shall not apply with respect to economisers, and
subsection (2)(c), (d) and (e) and subsection (1)(b) and (c) shall not apply
with respect to either economisers or superheaters.

(4) For the purposes of the foregoing provisions of this section, a
lever-valve shall not be deemed a suitable safety valve unless the weight is
secured on the lever in the correct position.

(5) Every part of every steam boiler shall be of good construction, sound
material and adequate strength, and free from patent defect.
