EN 14957:2006+A1:2010 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provisions of this type C standard are different from those which are stated in type 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 1.1 This European Standard applies to multizones dishwashing-machines with passing through motorized belt (flight type) or rack conveyor. In case of flight type, the loading and unloading areas are part of the machine. The machines covered by this European Standard are intended for washing, rinsing and optionally drying the dishes and the kitchen utensils, used in food and catering premises such as restaurants, hotels etc. This European Standard applies to dishwashing machines with conveyor with a linear speed less than or equal to 5 m/min for the dishes and kitchen utensils. NOTE Normally the total power of these machines is less than 200 kW. This European Standard deals with all significant hazards, hazardous situations and events relevant to dishwashing machines with conveyor, when they are used as intended and under the conditions foreseen by the manufacturer (see Clause 4). This European Standard deals with the hazards which can arise during commissioning, operation, maintenance and decommissioning of the machine. When drawing up this European Standard the following assumptions were made: only trained adult persons operate the machines; the machines are used in adequately illuminated areas. This European Standard, referring for electrical safety to EN 60204-1 with criteria that can be applied to different designs and variants, is mainly intended for machines manufactured in small series. 1.2 This European Standard does not apply to: separate mechanical loading and unloading conveyors; chemical dosing devices which are not incorporated into the machine; steam generators; gas heating equipment. 1.3 Noise is not considered to be a significant hazard for these machines. This does not mean that the manufacturer of these machines is absolved from reducing noise and making a noise declaration. Therefore a noise test code is included in Annex A. 1.4 This European Standard is not applicable to dishwashing-machines with conveyor which are manufactured before the date of publication of this European Standard by CEN. 2 Normative references The following referenced documents are indispensable for the application of this document.

NOTE Hazards of potable water network pollution are dealt with by EN 1717 or EN 61770. 4.7 Hazards generated by neglecting ergonomic principles Risk of injury or chronic damage to the body resulting from harmful body postures during operation (loading, unloading), cleaning (racks, filters, access doors) and during the hand loading of dosing devices and dispensers. 4.8 Hazard from loss of stability Impact or crushing hazard if the machine topples over. 5 Safety and hygiene requirements and/or protective measures 5.1 General Machinery shall comply with the safety requirements and/or protective measures of this clause. In addition, the machine shall be designed according to the principles of EN ISO 12100-2 for relevant but not significant hazards, which are not dealt with by this document. For hazards which are to be reduced by the application of the type B-standards such as EN 294, EN 349,

This specific risk assessment shall be part of the general risk assessment of the machine. !When interlocking devices are referred to in Clause 5, they should preferably be position detectors with positive opening contact complying with the recommendations of standard EN 1088:1995, 4.2.1 (interlocking without guard locking) and Clauses 5 and 6. However, due to practical reasons (e.g. cleaning), magnetic switches (reed switches) in accordance with EN 1088:1995 are allowed. The parts of the control system related to the interlocking shall meet at least category 1 of 6.2.2 of EN 954-1:1996 or present at least a performance level c defined in accordance with EN ISO 13849-1.

The risks due to drawing-in at the openings in the upper part of the belt (“e” in Figure 3) and/or touching the parts beneath (the lower part of the belt, or fixed intermediate elements) shall be reduced as much as possible by one or more of the following measures: reduction of the openings in the belt while achieving as much as possible compliance with Table 4 of EN 294:1992; an appropriate shape of the belt elements, in particular at the inside; the design of the intermediate elements (smooth surface, size and shaping of the openings etc.); the distance between the upper belt element and the lower element, or between the upper belt element and the intermediate element (“d” in Figure 3). For opening widths “e” of maximum 80 mm in the belt, the distance “d” should be more than 150 mm.

Different from the safety trip device, it is acceptable that disengagement of this device restarts the belt. Pegs shall not have sharp edges. 5.2.1.2 Reciprocating rack conveyor type machine Crushing points between accessible conveying elements and fixed parts shall be eliminated by minimum distance of 25 mm in accordance with EN 349.
