Belts and pulleys

(1) Machinery or plant not directly driven by an individual motor or other
prime mover but driven through a system of belt, pulley and shaft or
counter-shaft shall be equipped with-

   (a)  a clutch;

   (b)  a loose pulley; or

   (c)  other adequate means readily accessible to an operator for the
        effective starting and stopping of the machinery or plant.

(2) No driving belt shall rest or ride upon a revolving shaft forming part of
any transmission machinery.

(3) For the purposes of moving a driving belt to and from fast and loose
pulleys forming part of any transmission machinery, suitable striking gear
shall be provided and shall be constructed, placed and maintained so as to
prevent the driving belt from creeping back or shifting on to a fast pulley
while the driving belt is in motion on a loose pulley.

(4) Where a foot pedal forms part of any transmission machinery for the
purpose of operating a clutch, it shall be effectively guarded against being
unintentionally or accidentally struck so as to operate the clutch.
