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 for hazards relevant but not
significant, which are not dealt with by this document (e.g. sharp edges).
For hazards which are to be reduced by the application of a B-level standard the manufacturer shall carry out a risk
assessment to establish the requirements of the B-standard to be applied. This specific risk assessment is part of
the general risk assessment of the machine.
5.2 Common requirements for all shoe repair machines
5.2.1 Mechanical equipment
5.2.1.1 All transmission machinery and drive mechanisms which give rise to danger shall be enclosed by fixed
enclosing guards which satisfy EN 953.
5.2.1.2 Unless required otherwise by 5.3 and with consideration of risk assessment in accordance with EN
1050 hazardous movements of machinery parts, tools and work pieces shall be safeguarded by:
 fixed enclosing guards which satisfy EN 953;
or in case of technical impossibility
 fixed covers which satisfy Annex A of this document.
5.2.1.3 Safety distances and gaps shall comply with EN 294:1992, Tables 1, 3 and 4, unless specified
otherwise by 5.3.
5.2.1.4 Safeguards at crushing, shearing, drawing-in, trapping and friction points are not required, if the
2
maximum force of moving parts is limited to 150 N and the contact pressure is limited to 50 N/cm .
5.2.1.5 The surface of an area where the operator is standing for recurring manual intervention shall be even
and steps, slopes and protruding parts shall be avoided according to EN ISO 14122-1.
5.2.2 Electrical equipment
5.2.2.1 The electrical equipment shall be in accordance with EN 60204-1. With respect to some clauses of EN
60204-1:1997, stated hereafter, the following shall apply:
 4.3:
A.C. supplies: 4.3.2 applies without the note;
 6.2:
Protection in accordance with 6.2.2 or 6.2.3 and, where applicable, 6.2.4;
 9.2.5.3/4:
stop function and emergency stop: Category 0 or 1;
 9.4:
the safety related parts of the control system shall meet the requirements of 5.2.6.1 and 5.2.6.2 of this
document;
 12.3:
degree of protection: IP 43, when using electronics e.g. printed circuit boards: IP 54.
16

---------------------- Page: 17 ----------------------

EN 12387:2005 (E)
5.2.2.2 All operating control devices requiring frequent adjustment for altering process settings shall be located
outside the electrical cabinet.
5.2.3 Hot surfaces
Hot surfaces within reach which are not directly required for the working process shall be avoided or safeguarded
against accidental contact such that the temperatures of the burn threshold for the material concerned and a
contact time of less than 1 second, given in EN 563, are not exceeded.
5.2.4 Noise reduction
5.2.4.1 Noise control at the design stage
When designing the machine the available information and technical measures to control at source the noise from
machine parts, tools, hydraulic, pneumatic and extraction equipment shall be taken into account, according to EN
ISO 11688-1.
NOTE EN ISO 11688-2 gives useful information on noise generation mechanisms in machinery.
Examples for noise control measures are:
a) reduction of vibrations through static and dynamic balancing of the rotating parts;
b) reduction of vibrations within the machine by reducing both the mass of the moving parts and their
acceleration;
c) reduction of impactive over-clearance of rotational bearings by application of positive pre-loading;
d) proper choice and design of energy transfer components to eliminate bouncing;
e) proper choice and design of transmission components (gears, pulleys, belts, bearings etc.);
f) design of the machine structure which takes account of vibration, damping and avoiding structural resonances,
in particular coating of deflection rollers at scouring bands with damping rubber or felt;
g) fitting pneumatic exhaust silencers.
The above list is not exhaustive. Other noise control measures with the same or better efficiency can be used by a
manufacturer.
5.2.4.2 Noise reduction by information
If measures taken at the design stage are known to be insufficient to reduce noise emission to an acceptable level,
then the manufacturer shall give information on means to reduce noise further (see 7.3).
5.2.5 Dust detrimental to health
Shoe repair machines where the working process creates dust may be hazardous to health shall be fitted with an
integral extraction system or with connections for an external system.
Reduction of risk to health from dust shall be carried out by observing the state of the art, Clause 6 of EN 626-
1:1994 and Annex D of this document.
5.2.6 Control systems
5.2.6.1 Control systems shall comply with the following general requirements:
 electrical systems: 5.2.2 of the present document and Clause 9 of EN 60204-1:1997;
 pneumatic systems: the requirements of EN 983;
17

---------------------- Page: 18 ----------------------

EN 12387:2005 (E)
 for hydraulic systems: the requirements of EN 982.
5.2.6.2 Safety related control systems shall have at least the same level as the safeguarding used and shall
be at least in compliance with Category B of EN 954-1.
5.2.6.3 Means shall be provided to prevent uncontrolled starting of motors or movement of presses caused by
failure or unexpected reconnection of power supply. For the pneumatic and hydraulic systems this means can be
for example a pressure switch.
5.2.6.4 To avoid unintended operation foot-actuated controls, which actuate hazardous motions, control systems
shall be fixed to the frame of the machine and shall be safeguarded by a bridge shaped cover which prevent
unintended actuation by the operator or falling objects.
When selecting a bridge shaped cover for two or more foot-actuated controls the distance between the pedals shall
be more than 150 mm or, if less, a vertical divider shall be fitted between them.
5.2.7 Pressurized fluid systems
Equipment of hydraulic and pneumatic systems shall satisfy 4.10 of EN ISO 12100-2:2003, EN 982 and EN 983.
5.2.8 Ergonomics
When designing shoe repair machines basic ergonomic principles of 4.8 of EN ISO 12100-2:2003 shall be
considered.
5.3 Requirements for specific shoe repair machines
NOTE Following requirements apply also when the specific machine is integrated in a modular system.
5.3.1 Finishing machines for manual scouring, brushing, polishing and trimming operations
5.3.1.1 All rotating axles and shafts as well as tool shafts, nuts, bolt heads and fixing equipment, shall be
safeguarded by fixed enclosing guards which satisfy EN 953. Loose rolls around axles and shafts are considered
acceptable if they are designed and fitted such that its touch causes an immediate standstill of it.
Shaft ends do not need safeguarding if:
 they have a circular section;
 their surface is smooth;
 their exposed length does not exceed ¼ of their diameter or in case of bayonet catch 15 mm.
If the exposed length in case of a bayonet catch exceeds 15 mm a solution can be a bayonet cover designed to be
used with the loose roll.
5.3.1.2 Except for the section of the tools that is strictly for the work, scouring and polishing tools shall be
safeguarded either by:
 interlocking guards according to EN 953, EN 1088 and Annex A.2 or
 fixed guards according to EN 953 and Annex A.
Taking into account the technical constraint of the work, a hinged guard with key locking is considered acceptable.
The guard opening at the area of action shall comply for shoe repair finishing machines with Annex F, Figure F.1,
and for orthopaedic finishing machines with Annex F, Figure F.2.
5.3.1.3 Where the tool consists of an abrasive wheel, for sharpening the trimmer the wheel shall be protected
as much as possible by a fixed guard.
18

---------------------- Page: 19 ----------------------

EN 12387:2005 (E)
Detailed requirements are still under consideration, but for the moment being, the following is considered to be a
minimum.
a) The guard shall be made of steel, with a thickness of minimum 1,5 mm;
b) The guard shall be constructed and fitted in such a manner that in case of bursting flying parts shall be diverted
downwards;
c) The opening of the guard shall be limited to ≤ 120°.
