part of the machine specifically designed to provide protection by means of a physical barrier, such as, for example, a casing, a shield, a cover, a screen, a door, an enclosure or a fence; other parts of the machine that fulfil a primarily operational function, such as, for example, the frame of the machine, may also fulfil a protective function but are not referred to as guards
Note 1 to entry: Three main kinds of guards can be distinguished: fixed guards, interlocking moveable guards and adjustable guards. Interlocking movable guards are required where frequent access is envisaged, while fixed guards can be used where frequent access is not envisaged. |
