part of a machine specifically used to provide protection by means of a physical barrier. Depending on its construction, a guard may be called casing, cover, screen, door, enclosing guard, etc.
any device attached to or used in connection with a machine to reduce liability of injury to the operator
a protective device which, by means of a rail, grill or similar device provides the necessary safety distance preventing contact with the dangerous part
Kui töötamise või liikumise ajal on kukkumisoht, peab suurema kui 2-meetrise kukkumiskõrguse puhul rakendama ohutusabinõusid nagu kaitsepiirded, ohutusvõrgud jt analoogsed kaitsevahendid.
A guard may act:
- alone; it is then only effective when it is closed,
- in conjunction with an interlocking device with or without guard locking; in this case, protection is ensured whatever the position of the guard.
The moving parts of machinery must be designed, built and laid out to avoid hazards or, where hazards persist, fixed with guards or protective devices in such a way as to prevent all risk of contact which could lead to accidents.
