Introduction
This European standard is a "Type C" standard as defined in EN 1070.

The equipment concerned and the extent to which hazards are covered are indicated in the scope of this standard.

EN 617, EN 620 and EN 741 need to be considered for a complete continuous handling system (machine).

While producing this standard, it was assumed that:
 only suitably trained persons will operate the equipment;
 all parts of the equipment without specific requirements in this standard are:

 designed in accordance with the usual engineering practice and calculation codes (e.g. for mobile

equipment FEM 2 131/2 132 or ISO 5049-1, ...) including all failure modes;

 made of materials of adequate strength and of quality for their intended purpose taking into account all

failure modes using recognised design methods and appropriate safety factors;
 harmful materials, such as asbestos, are not used as part of the machine;

 components will be kept in good repair and working order in accordance with the manufacturer’s instructions,

to retain specified health and safety characteristics throughout its working life;

 by design of the load bearing elements, a safe operation of the equipment is assured for loading ranging from

zero to 100 % of the rated capacity;

 negotiations occur between the manufacturer and the user concerning materials characteristics (see Note 1)

and particular conditions for the use and places of use for the machinery related to health and safety;

 the place of installation is adequately lit.

NOTE 1 For the description of bulk materials, reference can be made to documents FEM 2 581/2 582 and ISO 3435.

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 over the provisions of other standards, for equipment that have

been designed and built according to the provisions of this type C standard.

1) “Manufacturer” within the European Union is to be understood as intended in the Machinery Directive.

j) biological and micro-biological (viral or bacterial) hazards;
k) hazards due to heat radiation from the materials handled;

l) hazards caused by operation in electromagnetic fields outside the range of EN 61000-6-2;

m) hazards caused by operation subject to special regulations (e.g. explosive atmospheres);

n) hazards caused by noise;

o) hazards caused by the use of ionising radiation sources (e.g. measurement equipment);

p) hazards caused by hydraulic equipment;
q) hazards caused by inadequate controls cabins lighting;
r) the risk related to elevating of the control stations;

s) hazards related to contact with or inhalation of harmful fluids, gases, mists, fums and dusts.

1.4 The safety requirements apply to equipment and systems placed on the market after the date of publication

of this standard.

NOTE 1 The requirements of this standard can be used for comparable machines outside the scope of this standard with the

same risks.

NOTE 2 Directive 94/9/EC concerning equipment and protective systems intended for use in potentially

explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard.

The present standard is not intended to provide means of complying with the essential health and safety

requirements of Directive 94/9/EC.

4 Hazards

This clause contains hazards and hazardous situations, as far as they are dealt with in this European standard,

identified by risk assessment significant for this type of machinery and which require action to eliminate or reduce

risk. Clause 5 deals with these hazards in the same order.

NOTE The hazards listed in Annex A usually occur in combination e.g. crushing, shearing and drawing-in.

5 Safety and EMC requirements and/or measures

Equipment and systems shall comply with the safety requirements and/or measures of this clause.

For the application of EN 953, EN 294, EN 811, EN 349, EN 1037, EN 60204-1 and !EN 60204-11" the

manufacturer shall carry out an adequate risk assessment for the requirements thereof where choice is necessary.

NOTE This specific risk assessment is part of the general risk assessment relating to the hazards not covered by this “C”

standard.

Belt conveyor mounted on the equipment shall be in accordance with !EN 620:2002+A1:2010" with the

exception of double safe way of escape.

Safety devices shall also be provided to prevent kickback of any manually operated crank.

In addition, the equipment shall be designed according to the principles to !EN ISO 12100" for hazards

relevant but not significant which are not dealt with by this standard.

NOTE The general safety requirements given in Clauses 5.1 to 5.12 are common to all types of mechanical handling

equipment dealt with by this standard. Clause 5.13 gives the specific safety requirements of some types of mechanical handling

equipment.
5.1 Mechanical hazards
Mechanical hazards shall be safeguarded preferably by guards.

Appropriate safety distances in accordance with Table 1 of EN 349 or Table 2, 3, 4 or 6 of EN 294 and EN 811

and/or hinged or sliding guards, fixed enclosing guards, fixed distance guards or interlocking guards shall be

provided to protect operators from crushing and shearing hazards.

For mobile equipment, visual warning devices such as flashing lamps and/or auditory warning devices shall be

fitted. If the driver cannot see the danger zone, the auditory warning devices shall provide a sound pressure level

15 dB(A) over the threshold of ambient sound pressure level at a height of 1,6 m from the floor at an horizontal

distance of 1m and shall be started 10 s before the start of the movement and provided during 3 s; the visual

warning devices shall operate throughout the equipment operation.
5.1.1 Guard construction

Guards shall be in accordance with EN 953 and may be perforated or imperforated sheet construction. If of

perforated construction, the safety distances to prevent danger areas being reached shall comply with EN 294.

Where it is intended to step on covers or guards, they shall be able to withstand a force of 1500 N evenly

distributed ov
