BS EN 1672 2:2005+A1:2009 EN 1672-2:2005+A1:2009 (E) 4 Introduction This document is a type C standard as stated in EN ISO 12100-1. The machinery concerned an
22、d the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. Here it has to be distinguished between the hazards to the operator and the risks to the food (the product processed by the machinery). This document addresses only those hazards w
23、hich are commonly occurring on food processing machines and for which technical specifications can be set which will apply to all (or most) of the classes of machines within the scope of the standard which have that hazard. In almost all cases at least one of the different methods of design, safegua
24、rding or other safety measures can be chosen which will meet both safety and hygiene essential requirements and adequately control both risks. The option to satisfy both hygiene and safety risks may not be the most obvious option which would have been adopted had the risk only been to safety or to h
25、ygiene, but will have to be the one chosen to meet both. The first choice is to select a design method which removes both hygiene and safety risks: if this is not within the state of the art then safeguarding options for both, or if not, one of the risks should be selected. Where no design or safegu
26、arding options are within the state of the art to adequately control both hygiene and safety risks then one of the risks, or both, would have to be dealt with by safety measures, including instructions to the user. The assessment of the respective safety and hygiene risks will indicate their relativ
27、e significance and the higher level of protection (i.e. safeguarding) should be implemented to deal with the severest risk and safety measures for the lesser risk. The technical requirements given in the prCEN/TR 1672-1 and in this document permit both objectives to be met for those significant and
28、common risks identified as justifying common requirements in this document. Other hazards, for which such common requirements can not be set, remain to be covered in machinery specific type C standard and/or by reference to EN ISO 12100-2 and type A and type B standards. When provisions of this type
29、 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. NOTE The essential re
30、quirements of the Machinery Directive should met in respect of both safety risks to the operator of the machinery and hygiene risks to the food (product processed by the machinery). The Directive requirements and the safety and hygiene risks identified by the risk assessment process required by EN 1
31、050 can each usually equally well be met by a range of safeguarding or hygiene design options. BS EN 1672 2:2005+A1:2009 EN 1672-2:2005+A1:2009 (E) 5 1 Scope This document specifies common hygiene requirements for machinery used in preparing and processing food for human and, where relevant, animal
32、consumption to eliminate or minimise the risk of contagion, infection, illness or injury arising from this food. It identifies the hazards which are relevant to the use of such food processing machinery and describes design methods and information for use for the elimination or reduction of these ri
33、sks. This document does not deal with the hygiene related risks to personnel arising from the use of the machine. This document applies to food processing machines Examples of such groups of food processing machinery are given in the informative Annex B. NOTE Separate hygiene requirements are contai
34、ned in other EU Directives (see Bibliography). In addition, the principles contained in this document can be applied to other machinery and equipment used to process food where similar risks apply. Examples of hygiene risks and acceptable solutions are given in the informative Annex A. This document
35、 is not applicable to machines manufactured before the date of publication of this document by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document.
