List of significant hazards 4.1 General This clause contains all the significant hazards, hazardous situations and events, as far as they are dealt with in this document, identified by a risk assessment as significant for catering attachments, and which require action to eliminate or reduce the risk. Before using this document, it is important to carry out a risk assessment of the catering attachment to check that its significant hazards are identified in this clause. 4.2 Mechanical hazards 4.2.1 For vegetable cutters and cheese graters  Access to cutting/grating tool through the hopper and discharge area. Hazard of cutting and abrasion for hand and fingers.  Access to cutting/grating tool when the cover is opened. Hazard of cutting and abrasion for hand and fingers. SIST EN 12851:2006+A1:2010

A permanent sign shall be affixed to the attachment for reminding that the cutter depth shall not be higher than 8 mm;  a cutter diameter (D) of maximum 230 mm;  a feed inlet circumscribed diameter (d) of maximum 150 mm;  the provision of a pusher device that descends by gravity for covering the feed inlet and that is shaped to the contours of the hoppers with a maximum clearance of 4 mm. For feed inlet circumscribed diameters of maximum 80 mm the pusher can be replaced with a plunger; SIST EN 12851:2006+A1:2010

 clearly visible and permanent safety signs shall be fitted to indicate the remaining hazard when introducing the hand into the hopper (see Figure 8). For their characteristics, EN 61310-1 applies. SIST EN 12851:2006+A1:2010

" Figure 8 — Safety signs 5.2.1.2 Safeguards against access to the danger zone by opening up of the cover The safety objective shall be to prevent access to the blade whilst it is still moving. This can be achieved by one of the following solutions:  solution similar to 5.2.1.1.1;  limiting the severity of the risk as set out in the firsts two indents of 5.2.1.1.3 and the following:  either a tool shall be required for the cover removal;
 or the design shall impose the operator to adopt a safe system at work and prevent impulsive opening of the cover, e. g. by requiring the use of both hands for the opening (see an example in Figure 9). The information for use shall include a warning about the dangers of removing the cover before the machine is at stand still. SIST EN 12851:2006+A1:2010
