ISO 11111-2:2005(E)
Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 11111-2 was prepared by Technical Committee ISO/TC 72, Textile machinery and machinery for dry-
cleaning and industrial laundering, Subcommittee SC 8, Safety requirements for textile machinery.
This first edition of ISO 11111-2, together with ISO 11111-1, ISO 11111-3, ISO 11111-4, ISO 11111-5,
ISO 11111-6 and ISO 11111-7, cancels and replaces ISO 11111:1995, which has been technically revised.

Introduction
ISO 11111-1 to ISO 11111-7 were prepared simultaneously by ISO/TC 72 and CEN/TC 214 and adopted
under the Vienna Agreement in order to obtain identical standards on technical safety requirements for the
design and construction of textile machinery.
ISO 11111 as a whole is intended for use by any person concerned with the safety of textile machinery, for
example, textile machinery designers, manufacturers and systems integrators. It is also of interest to users of
textile machines and safety experts.
This document is a type C standard as stated in ISO 12100-1. The various parts of ISO 11111 deal with
significant hazards generated by machines used in the textile industry. The machinery concerned and the
extent to which hazards are covered are indicated in the scope of this standard.
When provisions of this type C standard are different from those which are stated in type A or B standards, the
provisions of this type C standard take precedence.
For hazards of machines or machine elements not dealt with in the relevant part of ISO 11111, the designer is
to perform a risk assessment according to ISO 14121 and evolve means for reducing the risk from significant
hazards.
This part of ISO 11111 is intended to be used in conjunction with ISO 11111-1. As far as possible, the
requirements of this part of ISO 11111 are treated by way of reference to Clauses 5 and 6 of ISO 11111-1.
Clause 5 of ISO 11111-1 contains safety requirements and/or measures for frequently occurring hazards of
textile machinery which apply whenever referred to in this part of ISO 11111, while Clause 6 describes
significant hazards and corresponding safety requirements and/or measures for certain machine elements and
their combinations (e.g. rollers), which also apply whenever referred to in this part of ISO 11111.

Specific hazards
Mechanical, from drive and transmission parts for particularly dangerous machine elements, when the longest
stopping time exceeds the access time (e.g. crushing, shearing, entanglement, drawing-in and trapping).
Specific risks
Occasional access during special operations, particularly during changing of transmission parts, removal of
fibre material, cleaning, stripping, grinding, leading to high probability of severe injury. There is a particular risk
during run-down of rotating machine elements and associated drives.
Specific safety requirements
Interlocked movable guards with guard-locking in accordance with ISO 11111-1:2005, 5.3.3 shall be provided
for drive and transmission parts such that they cannot be opened or removed if required for technical reasons
until the drives and transmission parts have been brought to a standstill. For example, a guard-locking device
in conjunction with a motion sensor or a timer can be used for this purpose. The guard-locking device shall
ISO 11111-2:2005(E)
keep the guard closed when the control system or power supply fails. The precautions for drive and
transmission parts may be designed also to protect particularly dangerous machine elements simultaneously
[see ISO 11111-1:2005, 6.3 a)].
5.2.2 Automated blending bale openers
These include machines with a tower, running on a fixed track, parallel to which one or two lines of bales are
laid. A horizontal arm projects from the tower at right angles and has a milling head on its underside.
The operating area over which this machine works is relatively large. Ready access is required to the currently
non-operational side, or to the currently non-operational section, to install the next complement of bales in
their working position.
General safety requirements
The safety requirements of 5.2.1 shall apply.
Specific hazards
Mechanical, from the milling head, in particular, entanglement, drawing-in or trapping, impact, and from the
wheels, in particular, crushing.
Specific risks
Occasional access during normal operation, particularly for picking up flock from the floor and during special
operation, particularly cleaning and removal of blockages, leading to a moderate probability of severe injury.
Specific safety requirements
a) Automated blending bale openers shall be provided with guards or safety devices to prevent access to
the operating milling rollers.
b) In deviation from ISO 11111-1:2005, 6.3, this may be achieved by one of the following:
1) A trip device to stop the milling roller immediately when an operator enters the zone within which the
milling roller is operating. For example, a system of active opto-electronic protective devices (AOPD),
in accordance with ISO 11111-1:2005, A.2, may be used around the boundaries of the operating
zone, as in Figure 1, to act as a trip device.
Where the height of the fibre tunnel in the middle of the two operational zones is 300 mm or more,
the lower beam may be omitted in the tunnel area.
As an alternative to AOPD, pressure-sensitive mats and floor according to EN 1760-1 or pressure-
sensitive edges and bars according to EN 1760-2 may be used.
The restart control shall be located so that it cannot be actuated from inside the operation zone.
2) A provision during the normal production mode to protect any section of the milling roller not engaged
with a bale, either by completely encasing the roller or by fitting a trip device or devices that stop the
roller before access can be gained; provision shall be made for the rollers to come to a standstill as
soon as the milling roller traverses beyond the line of bales, or is raised above the bales.
In either case, a category of 3 or 4 according to ISO 13849-1:1999, Clause 6 of the safety related
part of the control system shall be selected.
c) A signal to warn of automatic restart shall be installed (see ISO 11111-1:2005, 5.4.2.3).
d) Suitable support devices shall be provided for the milling roller arm to prevent the arm dropping
unexpectedly. This may be in the form of two ropes, each of sufficient strength to support the arm.

ISO 11111-2:2005(E)
e) A warning shall be given in the instruction handbook concerning the need to install the machine in such a
position that the moving parts (e.g. the arm or the tower) do not pass closer than 500 mm to fixed
structures within the work area (see ISO 13854) or to safeguard the crushing zone .
f) A device shall be provided to bring the tower to a standstill before it reaches the end of the track (see
ISO 11111-1:2005, 6.21.3).
g) Wheels shall be protected according to ISO 11111-1:2005, 6.7.1.

Specific risks
Occasional access during cleaning of bit boxes and grinding, leading to low probability of severe injury.
Specific safety requirements
a) Where teasers are fitted with bit boxes, openings into the box shall be restricted in size or so shaped or
positioned that it is not possible to reach through and contact the swift (cylinder). Dimensions of access
openings shall be in accordance with ISO 13852.
b) Teasers shall be provided with interlocked sectional guards with guard-locking according to ISO 14119. If
sections of this guards can be removed to allow access for grinding devices, it shall not be possible to
start the teaser until the guards or the grinding devices are firmly in place and integrated into the guard-
locking system.
5.2.4 Bale breakers and hopper feeders
General safety requirements
The requirements of 5.2.1 shall be met.
Specific hazards
Drawing-in and trapping from the upright needle lattice winding onto the lower roller; puncture, crushing,
abrasion from the needles of the upright needle lattice, if the person is trapped between in-running bales and
the upright needle lattice.
Specific risks
Occasional access when removing flock and laps in front of the drawing-in zone of the on-running upright
needle lattice during intermittent standstill, leading to severe hand and arm injury; low probability of being
trapped between bales and the upright needle lattice leading to severe of fatal injury.
Specific safety requirements
a) Openings through which the drawing-in zone of the on-running upright needle lattice onto the lower roller
can be reached shall be safeguarded by interlocking movable guards. If stopping time exceeds access
time, the movable guard shall be guard-locked.
b) In the feeding zone where the bales run into the bale breaker, trip wires or trip bars or emergency
stopping devices (mushroom pushbuttons) on both sides shall be fitted for use by persons at risk of being
trapped between the in-running bale and the upright needle lattice.
5.2.5 Moving bin emptiers
A moving bin emptier is a unit arranged to travel on rails through a blending bin to remove the blended fibre.
For cleaning purposes, a platform is fitted at a high level on the emptier unit. Additionally, the unit can travel
sideways in order to empty a line of bins.
General safety requirements
The safety requirements of 5.2.1 shall apply.
Specific hazards
Mechanical, from the pinned lattice, in particular, entanglement, drawing-in or trapping; from sideways
movement of the emptier, in particular, crushing and shearing between the emptier and the bin and by the
platform and adjacent structures and between rails and wheels in falling from platforms.

ISO 11111-2:2005(E)
Specific risks
Occasional access during special operation, leading to low probability of severe or fatal injury.
Specific safety requirements
a) Access to the moving pinned lattice shall be prevented. This may be achieved by interlocking the pinned
lattice with the movement of the bin emptier so that the lattice stops before the bin emptier emerges from
the bin or the side guards, if fitted.
b) Movement of the lattice when the bin emptier is outside a bin or the side guards shall be possible only by
means of a hold-to-run device.
c) The movement of the bin emptier out of the bin shall be possible only by a hold-to-run control, unless a
trip bar or panel is fitted on the front side of the emptier.
The shear points which occur as the bin emptier enters the bin shall be safeguarded by one of the
following:
1) side guards extending outwards from the bin and conforming to ISO 11111-1:2005, 5.3.3;
2) trip devices (e.g. trip bars) conforming to EN 1760-2 mounted on the edges of the bin emptier;
3) a hold-to-run control actuated by an operator having a continuous view of both sides of the bin
emptier.
Wheels shall be protected according to ISO 11111-1:2005, 6.7.1.
d) Where the unit moves sideways, such movement shall be possible only with the lattice at rest, and in the
presence of one of the following:
1) a hold-to-run control fitted on the left side of the unit to move the unit left, and vice versa;
2) full-height trip bars according to EN 1760-2, provided for all shear points between the emptier and
the edges of the bin;
3) a distance between the emptier and the bin greater than 500 mm.
e) Platforms fitted to moving bin emptiers shall be equipped in accordance with ISO 11111-1:2005, 6.13.
Where access ladders are used instead of stairs, these shall be securely anchored when in use (see of
ISO 11111-1:2005, 5.6).
Where a platform is fitted on the bin emptier, provisions shall be made to ensure that the emptier unit
cannot be set in operation from the main control position when a person is present on the platform (e.g.
by a pressure-sensitive mat or floor according to EN 1760-1, or an interlocked door together with a reset
control). However, movement into, within or out of the bin shall be possible by means of a hold-to-run
control located on the platform, to enable the bin emptier to be used for cleaning the bin.
f) An emergency exit door shall be fitted at the extreme end of the bin according to ISO 11111-1:2005, 6.8.4.
If this door enables access to the bin, it shall be interlocked with the drive of the lattice.
g) Access to the top of the bin for maintenance purposes shall be provided by either of the following:
1) a platform conforming to the requirements of ISO 11111-1:2005, 6.13;
2) a device to which a safety harness may be attached in accordance with EN 795.

h) A warning shall be given in the instruction handbook concerning the need to install the machine so that
the moving bin emptier, including its platform, does not pass closer than 500 mm to fixed structures within
the work area.
5.2.6 Bunker emptiers
The floor of the bunker (bin) consists of a horizontal conveyor, which, when moving, brings the contents of the
bin towards the emptier section. The emptier is stationary during the process but can be moved sideways to
operate in an adjacent bunker.
Bins fitted with bunker emptiers which can move sideways shall conform to the requirements given in 5.2.5 c),
e), f) and g). Stationary bunker emptiers shall conform to the requirements of 5.2.5 e) and f).

Specific risks
Occasional access during normal operation, in particular, when attending to unevenly fed fibre at the
squeezing presses and incidental cleaning, or access during special operation (e.g. major cleaning or setting
up), leading to low probability of moderate-to-severe injury.
Specific safety requirements
a) Squeeze rollers and stripper rollers (where fitted) on the squeeze presses shall be guarded in accordance
with ISO 11111-1:2005, 6.5. These guards may be in the form of fixed distance guards extending along
the sides of the press in accordance with ISO 13852:1996, Table 1.
b) There shall be a clearance of at least 100 mm between the tips of the vanes of ducking rollers and an
adjacent part of the machine or, alternatively, the trapping area shall have side guards fitted in
accordance with ISO 13852:1996, Table 1.
5.4 Baling machines
Baling presses are used to compress fibres or waste into bales. They operate in either the vertical or
horizontal mode, depending on the direction of the movement of the ram. Precompressing devices may be
provided.
General safety requirements
The safety requirements and/or measures shall be in accordance with Table 3.

ISO 11111-2:2005(E)
Specific hazards
Mechanical, from the ram, in particular, crushing and shearing between the ram and other parts or crushing of
persons in the baling box; from a ram-type precompressing device, in particular, crushing and shearing
between ram and other parts; from a band conveyor type precompressing device, in particular, drawing-in;
from the doors of baling boxes, in particular, impact; from the press box and other machine parts during
movement of the press box, in particular, crushing; and also falling off working platforms.
Specific risks
Occasional access during normal operation, in particular, during removal of fibre material or opening the doors
of the baling box, and during special operation, in particular, during cleaning and maintenance work, leading to
low probability of severe or fatal injury.
Specific safety requirements
a) Access to the danger zones between the ram and other parts of the press, including those present on a
pre-compressing device, shall be prevented. This may be achieved by
1) totally enclosing the stroke area of the ram, for example with a tunnel guard; or equipping the ram
with a tunnel guard overlapping the edges of the baling box and other crush and shear points, when
the ram is in the open position,
2) interlocking any covers, flaps and doors with the movement of the ram to prevent access to crush
and shear points between the ram and other parts,
3) complying with the safety distances of ISO 13852, for all openings including the tying slots.
b) If converging band conveyors or a band conveyor and a roller are used for precompression, the drawing-
in points shall be protected in accordance with ISO 11111-1:2005, 6.10. This may be in the form of
enclosing guards together with an interlocked access door.
c) On hydraulic baling presses, the recoil of the ram due to the resultant stored energy in the bale shall be
prevented. This may be achieved, for example, by means of a suitable flow control valve.
d) Discharge doors and fastenings shall be designed to prevent uncontrolled opening under pressure. This
requirement may be met, for example, by using hydraulic guiding elements, threaded spindles or cams to
guide doors which are under pressure due to expansion of the bale, until the pressure is released.
In addition, the door of a horizontal baling press shall be interlocked with the movement of the ram such
that
1) the ram shall be able to effect a pressing movement if, and only if, the door is completely open or
completely closed, and
2) the door shall only be capable of being opened if the ram is in such a position that it exerts no
pressure upon the bale.
a) Means shall be provided for vertical presses to prevent falling of the ram when the hydraulic system fails.
b) Means shall be provided to prevent exposed persons from falling into open filling holes. This may be
achieved by ensuring that the rim of the filling hole is located at least 1 100 mm above the work level or a
surrounding fence 1 100 mm high is provided. The fence shall be infilled with sheeting, mesh or vertical
bars spaced at not more than 135 mm (see ISO 13853).
c) Flaps or doors to enable regular cleaning shall be safely accessible. Where cleaning cannot be carried out
safely from floor level because of the location of the baling press, safe work platforms shall be provided,
as specified in k).

ISO 11111-2:2005(E)
d) On presses where the baling box is automatically moved under power (e.g. rotary presses), access to the
danger zone (field of rotation) shall be prevented by one of the following means:
1) a fence guard (see ISO 11111-1:2005, A.3) around the field of rotation with interlocking doors;
2) a partial fence guard round the field of rotation and protection of the remaining area by photoelectric
protective devices (see A.2 of ISO 11111-1:2005) — when the door is opened or the photoelectric
protective devices are interrupted, it shall not be possible to start the changing process or, if such a
process is occurring, it shall be interrupted;
3) pressure-sensitive bumpers according to prEN 1760-3, fitted to those parts of frame or changing unit
which form crush and shear points — where the rotation of the box is controlled manually, this shall
be actuated by means of a hold-to-run control positioned so that the danger zones are in view;
4) the inertia shall be such that when the boxes are rotated, they are easily stopped by hand.
e) When baling presses are of the hand-operated type or when automatic presses are switched over to hand
operation, the ram shall only be activated by means of a hold-to-run contr
