EN ISO 14120:2015. Where no specific choice for a type of guard is specified in this document, the
guards shall be chosen using EN ISO 14120:2015.
Unless otherwise specified in this document the guards shall be dimensioned and positioned so that the
safety distances comply with those specified in EN ISO 13857:2019, Clause 4 and Annex A and B.
Unless otherwise specified in a machine specific standard, top-open distance guards shall be at least
2000 mm high from the floor or other plane of access, and the distance from the upper end of the
guards to the nearest hazard zone shall comply with EN ISO 13857:2019, Table 2. Where it is possible
to climb over a guard extending over a machine part like a conveyor or a tunnel the top of this part is
considered as a plane of possible access.
The machine controls shall ensure that hazardous movements stop before any hazard movement can be
reached after an interlocked moving guard has been opened. If this requirement cannot be achieved, the
guards shall be fitted with interlocking devices which prevent access to the hazard zone until the
hazardous movement has stopped. The guard locking device shall comply with EN ISO 14119:2013, 5.7,
and shall be installed according to 5.2 and 5.3 of that standard, and the stop shall be activated before
the guard is opened more than 50 mm.
4.3.4.2 Electro sensitive protection equipment (ESPE)
The minimum distance between the nearest hazard zone and an ESPE shall comply with
EN ISO 13855:2010, 6.2.
4.3.5 Discharge or transfer area
Shearing points and drawing-in points at the tray turning shall be guarded in accordance with 4.2.
The hazards are considered to be avoided when:
— the maximum opening of the gap is 4 mm; or
— danger points are safeguarded with guards or other protective devices.
4.4 Specific mechanical requirements for belt in-feed machines
4.4.1 General requirements
Transmissions, drawing-in between belt and driving wheel, drawing-in between belt and supports,
drawing-in between belts shall be safeguarded in accordance with 4.2 by:
— a fixed guard;
— a movable interlocked guard if the stop time is less than 2 s; or
— a movable interlocked guard with guard locking.
4.4.2 Feeding area
Drawing-in risks in the feeding area shall be avoided by safeguarding in accordance with 4.2.2.
4.4.3 Entrance to the processing area
Hazardous moving parts shall be safeguarded by fixed or interlocked moving guards complying with
EN ISO 14120:2015.
Where no specific choice for a type of guard is specified in this document, the guards shall be chosen
using EN ISO 14120:2015.
Unless otherwise specified in this document the guards shall be dimensioned and positioned so that the
safety distances comply with those specified in EN ISO 13857:2019, Clause 4, Annex A and B.
Unless otherwise specified in a machine specific standard, open topped distance guards shall be at least
2000 mm high from the floor or other plane of access, and the distance from the upper end of the
guards to the nearest hazard zone shall comply with EN ISO 13857:2019, Table 2.
Where it is possible to climb over a guard extending over a machine part like a conveyor or a tunnel the
top of this part is considered as a plane of possible access.
The machine controls shall ensure that hazardous movement stops before an interlocked moving guard
has been opened.
If this requirement cannot be achieved, the guards shall be fitted with interlocking devices which
prevent access to the hazard zone until the hazardous function has stopped. The guard locking device
shall comply with EN ISO 14119:2013, 5.7, it shall be installed according to EN ISO 14119:2013, 5.2 and
5.3, and shall be activated before the guard is opened more than 50 mm.
4.4.4 Electro sensitive protection equipment (ESPE)
Means of safeguarding against drawing-in risks shall be provided, e.g.:
— a trip device (e.g. trip wire or trip bar) stopping the movement before any hazardous parts or areas
can be reached (see EN ISO 13855:2010). The trip device shall be placed so hazardous areas cannot
be reached without activation of the device; or
— restricted size of opening to the processing area. Size of the openings shall comply with
EN ISO 13857:2019.
— an electro sensitive protection equipment which provides a minimum distance between the nearest
hazard zone and the ESPE in accordance with EN ISO 13855:2010, 6.2.
4.4.5 Processing area
Access to the processing area shall be prevented. This can be achieved by the use of fixed guards,
movable interlocked guards, a combination of both or the use of interlocking guard with guard locking.
The machine controls shall ensure that hazardous movements stop before any hazard movement can be
reached after an interlocked moving guard has been opened.
