Introduction
This document is a type-C standard as stated in EN ISO 12100:2010.
This document is of relevance, in particular, for the following stakeholder groups representing the market
players with regard to machinery safety:
— machine manufacturers (small, medium and large enterprises);
— health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.).
Others can be affected by the level of machinery safety achieved with the means of the document by the
above-mentioned stakeholder groups:
— machine users/employers (small, medium and large enterprises);
— machine users/employees (e.g. trade unions, organizations for people with special needs);
— service providers, e.g. for maintenance (small, medium and large enterprises);
— consumers (in the case of machinery intended for use by consumers).
The above-mentioned stakeholder groups have been given the possibility to participate in the drafting
process of this document.
The machinery concerned and the extent to which hazards, hazardous situations or hazardous events are

4 List of significant hazards
For an overview of all significant hazards dealt with in this document, see Annex C, Table C.1.
5 Safety requirements and/or measures
5.1 General
Machinery shall comply with the safety requirements and/or measures of this clause. In addition, the
machine shall be designed according to the principles of EN ISO 12100:2010 for relevant but not
significant hazards that are not dealt with by this document, e.g. avoidance of sharp edges.
5.2 Requirements for safety devices
5.2.1 The requirements of EN 1034-1:2021, 5.1 shall be satisfied.
5.2.2 The instruction handbook shall contain instructions for checking the safety devices.
5.3 Power transmission elements
Safety devices for power transmission elements between the drive and rotor or drum of the pulper shall
be selected and designed as specified in EN 1034-1:2021, 5.2.
5.4 Workplaces, access stairs, walkways, passageways
5.4.1 The requirements of 5.5 of EN 1034-1:2021 and EN ISO 14122-1:2016, EN ISO 14122-2:2016,
EN ISO 14122-3:2016, EN ISO 14122-4:2016 as well as of 5.4.2, 5.4.3 and 5.6.4 shall be satisfied.
5.4.2 Stairs and walkways on drum pulpers shall be fitted in such a way that in-running nips between
these elements and the drum are avoided. The safety distances specified in EN 1034-1:2021, 5.4 and in
EN ISO 13857:2019, Table 2 shall be applied.
5.4.3 Where access is required to parts of the machine, but is prevented or made difficult by the
position of the loading facility, crossovers or passageways shall be provided so that access to the loading
facility is avoided.
5.5 Falling hazard on pulpers
5.5.1 General requirements:
By appropriate design, installation and, if necessary, additional measures against tripping or falling, it
shall be ensured that persons cannot fall into the pulper. Fall-off protections, e.g. at the pulp tank or at
the entry openings of drum pulper shall be at least 1,20 m high (measured from possible standing level)
and designed in such a way that climbing up and falling through are prevented.
The distance between the pulper wall and the stand area at the pulper shall not exceed 0,12 m in order
to prevent tripping or falling.
Corrosion-resistant or galvanized material should be used for the construction of working platforms,
walkways, stairs and fall-off protections when exposed to moisture in order to prevent risks due to loss
of strength of the supporting elements as a result of expected excessive corrosion.
NOTE Continuous exposure to moisture is usually to be expected up to 2 m from the moisture source. In this
context, e.g. the raw material infeed could be considered as the moisture source. Therefore, e.g. for stand-alone
pulpers with a cover on the top, the area outside the tank will generally be considered dry, but not for pulpers
without a cover.
5.5.2 Danger of falling into stand-alone pulpers and under machine pulpers:
Persons are prevented from falling into the stand-alone pulper or machine integrated pulper, if:
— on stand-alone pulpers with a tank open at the top, the upper edge of the tank is at least 1,20 m above
standing level and the outer pulper walls are designed so that stepping up on them is not possible. If
the upper edge of the tank is lower, an additional fall-off protection shall be provided to meet the
requirements mentioned above;
— by closing the pulper tank with a load-bearing cover. If there are openings in this cover, they shall be
provided with closing lids or flaps. The closing lids or flaps shall be equipped with at least one handle
for opening. When the cover or flap is open, a grille permanently installed in the opening shall
prevent persons from falling through. Unintentional closing of the lid or flap from the open position
shall be prevented by design;
— in the case of stand-alone pulpers with openings in the side wall intended for the introduction of
additives by hand, if tilting devices, chutes, hoppers and similar devices are designed in such a way
that persons cannot climb onto them or fall through. Safety distances to the moving parts shall be
maintained in accordance with EN ISO 13857:2019, Table 2 and Table 4;
— on stand-alone pulpers with a mechanical loading facility, the charging opening is designed so that
no blockages of the loaded material can occur. This can be achieved by providing diverting bars
arranged at an appropriate distance in front of the charging opening. Working platforms at the end
of the charging conveyor shall be designed so that there is no risk of falling onto the conveyor or into
the pulper;
— on stand-alone pulpers with an access door (e.g. to enter with a ladder), allowing whole-body access,
the door shall be so designed that it open outwards only and by means of a special key or by
interlocking the door with the pulper drive (with or without guard locking based on the actual
stopping time) according to EN ISO 14119:2013, so that the pulper is at stand still when the door is
opened. The safety-related guard interlocking function shall meet at least EN ISO 13849-1:2015, PL
d or EN 62061:2005, SIL 2;
— on stand-alone pulpers and under machine pulpers with manual or gravity loading (e.g. web
unwinding from a drum), the dimensions given in Figures 4 and 5 are adhered to;
— on stand-alone pulpers where the charging conveyor is regularly walked on for operational reasons
(e.g. for the removal of cores on machinery with reel splitting machines), if a protection against
falling, adjustable if required, is provided in front of the feeding opening and access to the charging
conveyor is safeguarded by an interlocked door with guard locking. The interlocking device with
guard locking shall be designed so that access is possible only with the conveyor switched off and the
protection against falling is in its safeguarding position. The guard locking of the interlocking device
of the interlocked door shall not be released until the protection against falling is in its safeguarding
position. The associated control system for monitoring the protection against falling shall comply
with at least EN ISO 13849-1:2015, PL c or EN 62061:2005, SIL 1. When the interlocked door is open,
the restart of the charging conveyor shall be prevented. The interlocking function for the charging
conveyer shall comply with at least EN ISO 13849-1:2015, PL d or EN 62061:2005, SIL 2;
— on under machine pulpers located below paper making, board making or tissue making machines for
the recovery of waste (recovery stock) and which have a feed opening with a hatch, the fall of persons
into the pulper is prevented, if in front of this hatch an interlocking guard with guard locking in
accordance with EN ISO 14119:2013
