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.
