13. Machinery, general provisions
13.1. Construcflon and installation
13.1.1. All dangerous parts of moving machinery, including
the point of operation, should be effectively guarded unless they
are so constructed, installed or piaced as to be as safe as if they
were guarded by appropriate safety devices.
13.1.2. To ensure the safety referred to in paragraph 13.1.1,
in particular:
all flywheels, gearing, cone and cylinder friction drives, cams,
pulleys, belts, chains, pinions, worm gears, crank arms and
slide blocks and, to the extent prescribed by the competent
authority, shafting (including the journal ends) and other
transmission machinery also liable to present danger to any
person coming into contact with them when they are in motion,
should be so designed or protected as to prevent such danger;
controls should also be so designed or protected as to prevent
danger;
all set-screws, bolts and keys and, to the extent prescribed by
the competent authority, other projecting parts of any moving
part of machinery also liable to present danger to any person
coming into contact with them when they are in motion
should be so designed, sunk or protected as to prevent such
danger;
paths of counterweights, pendulum weights and the like
should be fenced; and
all working parts of machinery which, while in operation, may
produce flying particles should be, as far as is practicable,
adequately guarded.
13.1.3. Every power-driven machine should be provided
with adequate means, immediately accessible and readily identifiable
to the operator, of stopping it quickly, and preventing it from being
started again.
