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 prEN 1034-1:2019, 5.4 and
in prEN ISO 13857:2017, 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 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.
5.5.2 Danger of falling into stand-alone pulpers and under machine pulpers:
Persons are prevented from falling into the stand-alone pulper and 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, see;

---------------------- Page: 12 ----------------------
oSIST prEN 1034-4:2020
prEN 1034-4:2020 (E)
— on closed or covered stand-alone pulpers with cover openings, these openings are closed by covers
and, with the cover in open position, are protected by fixed grilles designed so that persons cannot
fall through. Covers shall be provided with side handles as well as adequate means for securing
them in the open position to prevent unexpected or unintended sudden closing ;
— on stand-alone pulpers with side openings for manually feeding stock mixtures, dump equipment,
chutes or similar facilities are designed so that persons cannot climb onto them or fall through, for,
parts, the safety distances of prEN ISO 13857:2017, Table 2 and Table 4 shall be applied 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 allowing whole-body access the door is to design to
open outwards and by means of a key access interlock or by interlocking (with or without guard
locking based on the actual stopping time) according to EN ISO 14119, so that the pulper is at stand
still or at hold to run function if the door is open;
— the safety related interlocking function shall meet at least EN ISO 13849-1:2015, PL d or
EN 62061:2005, SIL 2;
— the hold to run function if installed shall meet at least EN ISO 13849-1:2015, PL c or
EN 62061:2005, SIL 1;
— 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), protection against falling,
adjustable if required, is provided in front of the feeding opening and access to the conveyor is
safeguarded by an interlocking gate; the interlocking system 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 control system of the interlocking device shall comply with at least
EN ISO 13849-1:2015, PL c or EN 62061:2005, SIL 1;
— 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 is provided so that access is only possible with the
hatch closed. The control system of the interlocking device shall meet at least
EN ISO 13849-1:2015, PL c or EN 62061:2005, SIL 1. The hatch shall be designed or safeguarded in
such a way that crushing hazards are avoided in accordance with prEN 1034-1:2019, 5.3 and
EN ISO 13854:2019.
NOTE The function of the guard could alternatively be realized by a corresponding design of the cover.
