Overview - EN 972:1998+A1:2010 (Tannery machines, reciprocating roller machines - Safety requirements)

EN 972:1998+A1:2010 is a CEN Type C standard that sets safety requirements for reciprocating roller tannery machines used in processing animal hides and skins. It covers all life phases of the machine (design, manufacture, installation, operation, maintenance and decommissioning) and takes into account intended use, foreseeable misuse and component or system failures. The standard applies to a broad family of machines (buffing, polishing, ironing, carding, shearing, fleshing, shaving, wet wheeling, dehairing, staking, setting‑out, demanuring, sammying, etc.) and supports compliance with EU machinery directives (see Annex ZA).

Key topics and technical requirements

• Scope and machine types: Explicitly lists typical reciprocating roller configurations and provides informative descriptions (Annex D, figures 1–13).
• Risk assessment and hazards: Identifies significant hazards (mechanical, electrical, thermal, noise, entanglement, crushing, cutting, shearing, trapping, ejected objects, ergonomic risks, and hazards from materials/substances).
• Safety measures: Requirements for guarding, interlocking, prevention of unexpected start-up, safe control systems and protective devices aligned with EN ISO 12100 principles.
• Control systems & emergency functions: References safety-related control system design and emergency stop principles (EN ISO 13849-1, EN ISO 13850).
• Noise prevention: Design-stage provisions to reduce noise emission (Clause 5.2.4 and Annex A) - note the standard does not include a measurement/test code for noise emission values.
• Auxiliary hazards: Normative guidance on removal of harmful fluids/gases/dusts (Annex B) and fire prevention (Annex C).

5 !Safety requirements and/or protective measures"
!Machinery shall comply with the safety requirements and/or protective measures of this clause.
In addition, the machine shall be designed according to the principles of EN ISO 12100-2 for relevant but not
significant hazards which are not dealt with by this document.
For hazards which are to be reduced by the application of a type B-standard such as EN 13857, EN 953,
EN ISO 13850, EN 60204-1 etc., the manufacturer shall carry out a risk assessment to establish the
requirements of the B-standards which are to be applied."
5.1 !Common requirements concerning reciprocating roller machines"
5.1.1 Mechanical equipment
Safeguarding against the hazards generated by moving transmission parts (such as pulleys, belts, gears,
rack, etc.) shall be ensured by:
 Fixed enclosing guards in accordance with !EN 953 and 5.3.2.2 of EN ISO 12100-2:2003"
or
 Fixed and interlocking guards in accordance with !EN 953, EN 1088 and 5.3.2.3 of
EN ISO 12100-2:2003".
Hazardous motion of moving machinery parts, feed systems, tools and workpieces shall be safeguarded by:
 Fixed enclosing guards or covers which satisfy !EN 953 and 5.3.2.2 of EN ISO 12100-2:2003"
or
 !fixed distance guards which satisfy EN 953, 5.3.2.3 of EN ISO 12100-2:2003 and the distances given
in appropriate tables (I, III or IV) of EN ISO 13857."
All the guards shall be in accordance with clause 5 of EN 953:1997 (design and construction) and shall be
designed and manufactured in such a way as to keep all their functions during the application of a force of
800 N to the central zone of the guard, distributed over an area of approximately 0,01m .
On release of the force no detectable distortion of the guard shall remain.
!Fixing systems of fixed guards and fixed covers shall remain attached to these parts or to the machine
when the parts are removed."
!In case of technical impossibility of adopting the previous solutions, hazardous movements of machinery
parts shall be safeguarded by:"
!
a) movable interlocking guards which satisfy EN 953 and EN 1088 and 5.3.2.3 of EN ISO 12100-2:2003;
b) trip devices, such as:
 electro-sensitive protective devices satisfying EN 61496-1, CLC/TS 61496-2 and EN 999 and/or
 pressure sensitive edges or bars (defined in 3.1 and 3.2 of EN 1760-2:2001) satisfying
EN 1760-2."
!Unless demanded by 5.3 and 5.4, the related parts of the control system of the trip devices shall present a
performance level at least “d” defined in accordance with EN ISO 13849-1."
Requirements for guards and protective devices for particular machines/applications are given in 5.2, 5.3 and
5.4.
5.1.2 Emergency stop equipment
Manual controls (actuators) for emergency stop equipment shall be accessible to the operator(s) directly from
the operator position(s). They shall be so placed that their operation is simple and straightforward having
regard to the limited response which could be expected in a panic situation from persons who might also be
injured. It shall be possible for the controls to be operated by the head or knees of a person whose hands are
trapped at the operating position. Suitably placed trip bars, which extend the full width of the machine, satisfy
this requirement.
The actuation of a manual control shall cause:
 The rollers to open;
 Rotation of the rollers to stop.
The emergency stop equipment function shall be independent from the normal control systems of the machine
and shall comply with !EN ISO 13850", Category 1 requirements. For specific requirements of electrical
equipment 9.2.2, 9.2.5.4 and 10.7 of !EN 60204-1:2006" apply.
An acceptable arrangement is for a trip bar to operate in the positive mode one or more normally closed limit
switches, causing the auxiliary circuits to be broken.
The actuation of emergency stop control shall not create additional risks, e.g. stopping the fume extraction
equipment.
5.1.3 Control system
All machines shall have a start control fitted at the working zone.
5.1.3.1 Hydraulic systems shall be in compliance with EN 982, pneumatic systems shall be in compliance
with EN 983 and electrical systems shall be in compliance with EN 60204-1.
5.1.3.2 Devices shall be fitted, which in accordance with !EN 1037" prevent uncontrolled dangerous
movements caused by irregularities, failure or unexpected reconnection to the power supply, or due to the
control circuit being switched off.
5.1.3.3 Unless required by 5.3, safety related parts of the machine control system
 Shall have at least the same level as the safeguarding used or, where not otherwise specified,
 !shall present a performance level at least “c” defined in accordance with EN ISO 13849-1."
5.1.3.4 The use of programmable electronic systems (PES) shall not reduce any level of safety laid down
in this standard. When a machine is fitted with programmable electronic systems, safety related function shall
not rely solely on it. This requirement is met, by the use of:
 An additional hardwired control system,
or
 Duplicated solid state channel
5.2 Requirements for hazards in all danger zones
5.2.1 High pressure fluid ejection
If a machine is fitted with hydraulic/pneumatic equipment a loss of fluid under high pressure may arise and
result in a hazard of impact either directly or by impelled objects.
Where heated rollers are liquid filled, there is a hazard of scalding by the escaping fluid.
Requirements included in !EN 982" (hydraulic equipment) and !EN 983" (pneumatic equipment)
apply.
Where there is risk of injury by escaping spurts/jets of fluid or impelled objects this risk shall be reduced to the
lowest practical level by the provision of fixed enclosing screens.
5.2.2 !Electrical hazard"
In the design, construction, and use of all machines !EN 60204-1" shall apply.
Control and safety devices shall be protected to IP55 level if working in a wet process and IP54 if working in a
dry process as defined in !EN 60529".
5.2.3 !Slip, trip and fall hazard"
!Slip, trip and fall hazards relate mostly to dewooling, scudding, unhairing, fleshing and demanuring
machines."
Care shall be taken in the design of machines to safeguard against these hazards arising from and during the
use of the machine. These hazards, particularly that of slipping, may arise during the working of wet and/or
fatty material.
The need to provide, at machine installation, safeguards such as footboards, non-slip floors etc, shall be noted
in the instruction handbook (see !7.3.2 j)").
5.2.4 Noise
Noise reduction is possible by incorporating, as integral part of the design, one or more of the features
indicated in annex A of this European standard.
5.2.5 !Biological hazard"
!Biological hazards relate mostly to dewooling, scudding, unhairing, fleshing and demanuring machines."
The machines shall be designed taking into account the need to remove the waste products. As much as is
practicable, cleaning shall be possible without removal of guards. Suitable instruction shall be provided and
described in the instruction handbook (see !7.3.4 f)").
5.3 Requirements for hazards in the working zone
5.3.1 When the machine is open, contact with the working cylinder may cause:
 Cutting and entanglement hazards in fleshing (figure 9), demanuring (figure 10), and shaving (feed-out)
machines (figure 12)
 Entanglement and friction/abrasion hazards in setting-out (figure 6), dewooling (figure 6), scudding (figure
6), unhairing (figure 6), sammying (figure 6), cylinder ironing (figure 7) and cylinder staking (figure 8)
machines.
See position B in figures 6, 7, 8, 9, 10, 11, 12.
A movable guard shall be synchronised with the machine cycle so that the working cylinder is automatically
covered when the feed rollers open.
The synchronising of the guard movement with the machine cycle may be effected by means of a positive
mechanical connection to the machine opening and closing mechanism.
This requirement shall not apply to lower working cylinder of cylinder stacking machines (see figure 8B zone
1/A).
This requirement shall not apply to the lower working cylinder of cylinder stacking machines, because of the
need for adjustment depending on the working process. The guard, in this case, should be adapted too, but
due to the reduced space, the guard should be obliged to turn in such a way to collect waste materials,
causing dangerous failures.
For other design solution, if a failure occurs, the closing machine movement shall be prevented and the
working cylinder stopped.
!The guarding arrangements shall be interlocked with the opening and closing movements and the related
parts of the control system shall be present a performance level at least “d” defined in accordance with
EN ISO 13849-1."
5.3.2 In all machines the operator (or operators) handles skins and hides with one or both hands; for this
reason operator(s) shall drive the opening and closing movements of the machine utilising one pedal (or two
pedals).
Moreover, the converging movement of the transport rollers whilst the machine is closing, and any converging
rotation of the transport rollers when the machine is closed, may cause crushing, entanglement or trapping
hazards.
See position A in figures 1 to 13.
Safety requirements a and b shall apply.
a. Trip device
!A pressure sensitive protective edge or bar complying with EN 1769-2, and with the related parts of control
system presenting a performance level at least “d” defined in accordance with EN ISO 13849-1, shall be
installed, covering the entire working width of the machine, in order to detect any potential intrusion into the
danger zone."
a) The construction of the barrier shall allow a limited adjustment such that the distance between the edge of
the trip device and the surface of the skins being processed can be set. A statement shall be included
under operator instructions in the handbook noting that for optimum safety the setting should not normally
exceed 12 mm from skin surface.
With this setting, the skins can be processed and the operator's fingers can actuate the barrier before
they reach the danger point.
b) Where machines which can only feed out and have been fitted with an electro-sensitive protective device
as in the case of the machines indicated in figures 6, 7, 8, 9, 10, 11 and 12, the normal operating setting
of the pressure sensitive protective device may be increased up to 26 mm from skin surface, for
processing heavy hides.
The trip device barrier shall be constructed so that it will be actuated by a movement in the same direction as
the approaching movement of the carrier roller and also, for those machines which feed in, a movement in the
same direction as the infeeding material.
The positioning of the barrier shall be such that during the approach of the carrier roller and during the
actuation of the safety barrier it shall not be possible for a trap to occur between the barrier and the surface of
the approaching roller.
Actuation of trip device barrier shall cause the following actions:
 If the machine is closed or closing, the machine shall return immediately to its fully open position and feed
movement shall stop before the distance between the barrier and the pinch point has been covered by
the surface of the roller;
 If the machine is open, initiation of the closing movement or feed rotation shall be prevented.
After actuation of trip device barrier, initiation of closing movement shall not be possible until the operating
control switch has been released and actuated again, or a separate reset control has been actuated.
b. Double and single pedal operation
Machines wider than 1800 mm are to be fitted with two controls e.g. foot operated pedals.
The design of the control system shall allow the machine to be operated by the use of either one or two
controls. The control changeover shall be effected by means of a switch having a removable key.
When wide or difficult-to-handle skins which require two operators are processed, safe operation requires that
both controls shall be used, one by each operator. In that operating mode:
 The machine shall only close when both controls are pressed;
 It shall not be possible to initiate the next cycle before both controls are released and the machine has
opened fully;
 The machine shall immediately open if either of the operating controls is pressed or, where a hold-to-run
control is used, the machine shall immediately open if either of the operating controls is released.
Safe operation for a single operator requires that only one pedal be used, the other having been muted by use
of the control changeover switch.
Suitable information/instruction shall be provided (see !7.3.4 g)").
Foot-actuated controls on any trailing table fitted shall be safeguarded against accidental operation by the
provision of a cover.
5.3.3 In setting-out, dewooling, scudding, unhairing, sammying, cylinder ironing, cylinder staking, fleshing,
demanuring, wet wheeling and shaving (feed-out) machines, the converging movement of the transport
rollers, whilst the machine is closing, may cause a crushing hazard.
See position A in figures 6, 7, 8, 9, 10, 11 and 12.
Trip devices non-mechanically actuated shall be used.
!An electro-sensitive protective device of type 2 in accordance with EN 61496-1 and CLC/TS 61496-2 shall
apply. The related parts of control system of this device shall present a performance level at least “d” defined
in accordance with EN ISO 13849-1."
The beam or the beams of the photoelectric barrier shall be installed over the feeding zone, parallel to the
rollers and shall extend along their whole length.
The beam shall be broken by movements of the hand or an arm of the operator into the area between the
surfaces of the two rollers.
Braking the beam shall:
 Prevent the start of the closing movement;
 Immediately reverse the closing movement and return the rollers to the fully open position.
The device may be muted during the closing movement when the distance between the surfaces of the rollers
is less than 60 mm.
5.3.4 In setting out and cylinder ironing machines, possible contact with the heated working roller may cause
burns and scalds.
See position E in figures 6 and 7.
Where it is possible, accessible surfaces having a temperature exceeding the "no-burn" zones indicated in
!EN ISO 13732-1" shall be made inaccessible by heat insulating materials, which shall not contain
dangerous materials, e.g. asbestos, or by fixed distance guard in accordance with !EN ISO 13857".
Where it is not possible to protect the surfaces, warning signs shall be fixed to the machines and gloves or
other personal protective equipment shall be recommended in the instruction handbook.
5.3.5 In buffing, polishing, ironing (woolskins and fur), carding, shearing (woolskins and fur), cylinder
universal staking, setting-out.
In buffing, polishing, ironing (woolskins and fur), carding, shearing (woolskins and fur), cylinder universal
