    Effective guards

    Explanation:

    Risks appear when parts of the machine move or have the potential to move. The movements can be rotation, displacement, transverse or alternative (eg from top to bottom or from back to front).

    Basic types of guards or effective protections on machines. There are in many ways, including:

    - Guards, physical barriers designed as part of the machine, or added to the machine, for example envelopes (fixed or mobile), covers, shields, etc;

    - Presence Detection devices, do not prevent access but stop the movement of dangerous parts before contact with them is achieved, for example light curtains, area scanners and pressure mats;

    - Protection devices, do not prevent access or stop the machine but allow safer operation. For example, "dead man" or "double keypad" devices;

    - Alarms and Warnings, warn staff about the dangers. They can be permanent (eg warning signs) or activated when hazards appear;

    - Emergency stops, do not prevent access to dangerous parts or risk, but if activated during an emergency, they can avoid incidents or reduce them significantly.

    Before selecting the type of guard, a machine risk assessment must be carried out.
