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.
