ERMS AND DEFINITIONS
TERM
DEFINITION
PROTECTION
DEVICES
Safety measures involving the use of specific technical means called
protection devices (guards, safety devices) to protect persons from
dangers that cannot be reasonably eliminated or sufficiently reduced
in the design of the machine.
GUARD
A part of the machine specifically used to provide protection by the
use of a physical barrier. Depending on how it is made, a guard may
be called a cowling, cover, screen, door or fence etc.
Note 1
- A guard may act:
- alone; in this case it is effective only when closed.
- associated with a locking device with or without locking the guard;
in this case protection is assured whatever the position of the guard.
Note 2
- “Closed” means, in the case of a fixed guard, “kept in
position”.
FIXED GUARD
Guard kept in position (i.e. closed), by means of a fastening (screws,
bolts etc.) that make its removal/opening impossible without the use
of tools.
MOBILE GUARD
Guard that is generally mechanically connected to the frame of the
machine or to nearby fixed element (by means for example of hinges
or guides), and that can be opened without the use of tools.
INTERLOCKED
MOBILE GUARD
Guard associated with an interlock device so that:
The machine's dangerous functions “protected” by the guard cannot
be carried out unless the guard has been closed.
If the guard is opened during the unfolding of the machine's
dangerous functions, a stop command is given.
The closure of the guard permits execution of the machine's
dangerous functions “protected” by the guard but it does not control
the start up.
