Food processing machinery - Portable and/or hand-guided machines and appliances with mechanically driven cutting tools - Safety and hygiene requirements
This European Standard covers portable and/or hand-guided machines and appliances equipped with mechanically driven cutting tools. This European Standard specifies requirements for the design and manufacture of portable and/or handguided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools (see Figures 1 to 9), hereinafter referred to as “machines”. The machines covered by this European Standard are used for slaughtering animals, for cutting up animal carcasses, poultry and other foodstuff such as e.g. fish. They are mainly intended for use in slaughterhouses and rooms, which are used for cutting and preparing. These machines are used for the industry and trade. This European Standard specifies all significant hazards, hazardous situations and events relevant to the machines in the scope, 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 hazards which can arise during commissioning, operation, maintenance and de-commissioning of the machine. This European Standard is not applicable to portable and/or hand-guided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools, which are manufactured before the date of publication of this European Standard by CEN.

1 Scope 1.1 This European Standard covers portable and/or hand-guided machines and appliances equipped with mechanically driven cutting tools. This European Standard specifies requirements for the design and manufacture of portable and/or hand-guided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools (see Figures 1 to 9), hereinafter referred to as “machines”. The machines covered by this European Standard are used for slaughtering animals, for cutting up animal carcasses, poultry and other foodstuff such as e.g. fish. They are mainly intended for use in slaughterhouses and rooms, which are used for cutting and preparing. These machines are used for the industry and trade. !This European Standard specifies all significant hazards, hazardous situations and events relevant to the machines in the scope, 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 hazards which can arise during commissioning, operation, maintenance and de-commissioning of the machine. This European Standard is not applicable to portable and/or hand-guided machines and appliances equipped with electrically, hydraulically or pneumatically driven cutting tools, which are manufactured before the date of publication of this European Standard by CEN. 1.2 This European Standard covers the following machines subdivided into tool types: 1.2.1 Saws (see Figures 1 to 5) Circular saws (see Figures 1 and 2); straight blade reciprocating saws (see Figures 3 and 4); band saws (see Figure 5).

Portable and/or hand-guided machines are constructed of a machine housing with a motor or pressure cylinder within the housing, or a motor which drives the tool via a flexible drive cable, the tool being hand-held at the place of use or being hand-guided on a movable device. The motor or drive can comprise electrical, hydraulic or pneumatic components. For weight balancing, a suspension unit with a tensioning spring or a counter-balancer can make the work easier for the operator. This equipment is not covered by this European Standard. 1.3 Intended use Portable and/or hand-guided machines are used on suspended or lying, stunned and blood-drained animals for cutting off legs, feet and horns, for cutting out anuses, for skinning, for opening the sternum, for halving, quartering or further cutting carcasses and for removing fat. Although it should be advised against, this European Standard, taking into account practice, deals with the hazards due to cleaning with pressurised water. With the aim of clarifying the intentions of this European Standard and avoiding doubts when reading it, the following assumptions were made for operation: only designated and instructed persons operate the machine, place of use is adequately lit, and the equipment will be used in an environment with hygiene hazards but without other special hazards.

In addition, they shall be designed according to the principles of EN ISO 12100 for hazards relevant but not significant, which are not dealt with by this European Standard (e.g. sharp edges). !For hazards which are to be reduced by the application of the type B-standards such as EN 614-1, EN 953, EN 60204-1, EN 60529, EN ISO 12100, EN ISO 13849-1 and EN ISO 13857, the manufacturer shall carry out a risk assessment to establish the requirements of the type B-standard. This specific risk assessment shall be part of the general risk assessment of the machine." Where the means of reducing the risk is by the physical arrangement or positioning of the machine the manufacturer shall include in the information for use a reference to the reduction means to be provided, and to any limiting value of the requirement, and, if appropriate, to the means of verification. Where the means of reducing the risk is by a safe system of working the machinery, the manufacturer shall include in the information for use details of the system and of the elements of training required by the operating personnel. 5.2 Mechanical hazards 5.2.1 General Portable and/or hand-guided machines shall be designed and constructed in accordance with the conditions mentioned below and Annex B. 5.2.2 Zone 1 – Cutting part 5.2.2.1 Non-cutting part of circular saws Circular saws shall be provided with guards made of a material strong enough to contain any part of a blade which might be ejected due to failure. The guards shall have the following characteristics: 5.2.2.1.1 Circular saws shall be provided with a fixed guard (see EN ISO 12100-1:2003, 3.25.1) covering the part of the blade which is not required for sawing for an angle β

For this type of saw a two-hand control of at least type I, EN 574 shall be used. ! 5.2.2.1.3 Fixing systems of fixed guards shall remain attached to these guards or to the machine when the guards are removed." 5.2.2.2 Non-cutting part of band saws !Band saws shall be so designed and constructed that access to the parts of the blade which are not used during operation is prevented by a interlocking guard with locking according to at least Performance Level “c” or “d” of EN ISO 13849-1:2008 (see 3.25.4 of EN ISO 12100-1:2003). Alternatively a two-hand control according to type I of EN 574:1996 can be used.
