Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom. SIST EN 1672-1:2014



EN 1672-1:2014 (E) 6 Introduction Food processing machines are used extensively in Europe, in domestic, catering and industrial applications. They present many health and safety hazards and have the potential to cause serious injury. At the time of publication of this European Standard there exist about 50 European C-standards for all kinds of food processing machinery. Yet, some food processing machines are so specific and their variety is so large that it is not possible to sufficiently cover all types by machine-specific standards. EN 1672-1 therefore addresses those food processing machines that are not covered by one of the machine-specific standards that are listed in Annex C. The extent to which hazards are covered by this document is indicated in the Scope and Clause 4. SIST EN 1672-1:2014



EN 1672-1:2014 (E) 7 1 Scope This European Standard deals with the significant hazards, hazardous situations and events relevant to commercial and industrial food processing machines as defined in Clause 3 when they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard deals with the significant hazards, hazardous situations and events that occur during transport, assembly and installation, commissioning, setting, teaching, programming, process changeover, operation, cleaning, fault finding and maintenance. This European Standard deals with those risks which occur commonly in food processing machines and for which common technical requirements can be set which can be applied at all (or most) machines which have that particular hazard. Exclusions: This European Standard is not applicable to the following machines: — food processing machines intended for domestic use; — food processing machines covered by the machine-specific standards listed in Annex C; — packaging machines; — machines used in the agricultural and animal rearing sectors. This European Standard does not deal with the hygiene risks to the consumer of the food product handled in the food processing machine. These risks are dealt with in EN 1672-2:2005+A1:2009. This European Standard is not applicable to food processing machines that were manufactured before the date of its publication as a European Standard. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Introduction
Food processing machines are used extensively in Europe, in domestic, catering and industrial applications. They
present many health and safety hazards and have the potential to cause serious injury.
This document is a Type C standard as defined in EN ISO 12100.
The extent to which hazards are covered by this Standard is indicated in the scope and Clause 4 of this Standard.
In addition, machines should comply as appropriate with EN ISO 12100 and other appropriate European and
International standards for hazards that are not covered by this document.
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 the other standards for machines that
have been designed and built according to the provisions of this Type C standard.
1 Scope
This European Standard deals with the significant hazards, hazardous situations and events relevant to commercial
and industrial food processing machines as defined in Clause 3 when they are used as intended and under
conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).
This document deals with the significant hazards, hazardous situations and events that occur during transport,
assembly and installation, commissioning, setting, teaching, programming, process changeover, operation,
cleaning, fault finding and maintenance.
This European Standard deals with those risks which occur commonly at food processing machines and for which
common technical requirements can be set which can be applied at all (or most) machines which have that
particular hazard.
This standard is not applicable to the following machines:
 food processing machines intended for domestic use;
 food processing machines covered by the machine specific standards listed in Annex C;
 packaging machines;
 machines used in the agricultural and animal rearing sectors.
This standard does not deal with the hygiene risks to the consumer of the food product handled in the food
processing machine. These risks are dealt with in EN 1672-2.
This document is not applicable to food processing machines that were manufactured before the date of its
publication as a European Standard.

4.1 General
This clause lists the wide range of hazards, hazardous situations and events that can be found on food processing
machines and their associated equipment.
The manufacturer of a food processing machine can use this list of hazards to help identify the hazards on his
machine and then find appropriate safety requirements for each of these hazards in the corresponding subsections
of Clause 5 of this document.
If the manufacturer identifies hazards on his machine that are not listed in this clause, he shall assess these
hazards by using the principles detailed in EN ISO 12100.

---------------------- Page: 10 ----------------------
oSIST prEN 1672-1:2012
prEN 1672-1:2012 (E)
The hazards on a particular food processing machine can vary depending on the product being processed and any
ancillary equipment that may be supplied with or connected to the machine.
4.2 Mechanical hazards
4.2.1 Moving parts
4.2.1.1 General
Most food processing machines, whether intended for commercial or industrial use, incorporate mechanical
mechanisms, which can cause moderate or disabling injuries. Typical mechanical hazards caused by moving parts
on food processing machines include:

a. crushing hazards – e.g. caused by tools or drive mechanisms, gears and chains and sprockets;
b. shearing hazards – e.g. caused by tools or transfer mechanisms, rotary valves, dividing mechanisms;
c. cutting hazards – e.g. caused by cutting devices during operation, machine intervention, cleaning and
handling, sheet metal edges that have not been deburred;
d. entanglement hazards – e.g. caused by mixing tools, rotating shafts;
e. drawing-in and trapping hazards – e.g. caused by milling or gauging rollers, drive rollers on belt conveyors;
f. impact hazards – e.g. caused by unsupported lids or covers, small machines falling off work surfaces;
g. stabbing and puncture hazards – e.g. caused by meat injectors;
h. friction and abrasion – e.g. caused by conveyor belts, drive belts;
i. ejection of parts hazards – e.g. caused by products in rotating bowls, break-up of high speed rotating
components.
4.2.1.2 Risks arising from frequent operator intervention
4.2.1.2.1 General
On food processing machines, the risks from moving parts are increased in comparison to similar machinery used
in other industries because of the need for frequent operator intervention. There is a need for frequent intervention
into danger zones to remove blockages, to assist product flow (especially the last piece of a product run), to clean
between different product runs and to gain access to the machine parts for a thorough clean to meet food hygiene
requirements.
4.2.1.2.2 Openings in machines
There is a risk from danger zones on food processing machines, when operators reach into infeed, outfeed and
inspection openings to load product, unload product, and assist product flow and to clean the machine.
4.2.1.2.3 Reaching over guards
There is a risk from danger zones on food processing machines, when operators stand on parts of machines or
mobile steps and reach over guards to assist product flow or to clean the machine while the machine is running.
4.2.2 Risks which may arise from hygienic design features
4.2.2.1 General
Design features that make a food processing machine easy to clean can expose operators to hazards on the
machine if they are not correctly designed.

prEN 1672-1:2012 (E)
4.2.2.2 Quick release fixings
Quick release fixings that can be undone without the use of tools are frequently fitted to food processing machines
so that machines can be dismantled quickly for cleaning. A risk may arise if the removal of quick release fittings
allows access to danger zones.
4.2.2.3 Cleaning space under machines
There is a risk from danger zones on food processing machines, if operators kneel on the floor and reach under
guards to clean the machine or the floor under the machine when the machine is in motion as shown in Figure 1.
This risk is increased if an open design structure has been used to allow food to fall freely through the machine’s
mechanisms onto the floor.

4.2.2.4 Spillage trays
Food processing machines may be fitted with trays to collect spillages of food from the machine. It is good hygienic
design practice for spillage trays to be easily removable so that product can
