In addition, the machine shall be designed according to the principles of EN ISO 12100 for relevant but not significant hazards which are not dealt with by this document. 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 these means, 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 work, 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 Portion cutting machines shall be designed and constructed in accordance with Annex C and the conditions mentioned below. The guards shall comply with EN 953:1997+A1:2009. Fixing devices for fixed guards shall remain on the guards or on the machine if the guard is removed. Unless otherwise stipulated in other sub-clauses, the interlocking systems of guards shall comply with EN ISO 14119:2013, 4.2, and the safety related components of the control system shall present at least a performance level “c” of EN ISO 13849-1.

Inlet opening or inlet tunnel An unclosed inlet opening or an inlet opening closable with an interlocking or protective guard can be implemented at the supply side for the automatic loading.

The openings and safety distances shall correspond to EN ISO 13857:2008, Table 4. If the intervention is prevented by the downstream auxiliary component, it shall be ensured that the protection function of the auxiliary component is retained. This can be achieved e.g. by side guide plates, limit stops or interlocks. 5.2.4 Zone 3 – Movable guards 5.2.4.1 Manually operated guards A handle shall be provided on the manually operated guard. A handle can be dispensed with if the guard is designed so that it can be securely held and operated. The force required for lifting or lowering a guard may not exceed 250 N. Movable guards shall be secured against falling down. This is achieved by e.g. the following measures: — The movable guard shall be located far behind the dead centre in the open position. — If the movable guard is not far enough behind its dead centre in the open position, e.g. a counterweight, a spring or a mechanical latching device shall prevent falling. Guards that can assume their protection position without guard locking shall be locked with the mechanical drive. Normally, fixed guards, also those that are mobile in design for ergonomic reasons and only have to be opened for maintenance or repair and are not intended to be opened by the operator, are excepted from this. 5.2.4.2 Force-operated guards As long as the hazards cannot be prevented by the design (e.g. advancing deflector), the risk of crushing in force-operated guards shall be protected e.g. by the following methods: SIST EN 13870:2015
¶ 6 mm, is the guard locking (see 5.2.12.3) released. When locking with a locking force, this shall be minimum 200 N. — The guard closes with a crushing force of maximum 135 N or an impact force of maximum 180 N and a speed of maximum 200 mm/s. Only in the work position, if the distance from the guard to the closing edge is
¶ 25 mm, is the guard locking (see 5.2.12.3) released. When locking with a locking force, this shall be minimum 300 N. The distance up to the first hazard point shall be minimum 450 mm. — The guard closes with a speed of maximum 50 mm/s, if the distance from the guard to the closing edge is
¶ 200 mm. The closing speed shall not be more than 50 mm/s up to a minimum distance of 200 mm. — No handle may be mounted on force-operated guards that are locked by a retaining force. — If the drive energy fails (e.g. power failure, tube or hose breakage), the movement of the force-operated guard shall be interrupted if a crushing force of 135 N is exceeded. Safety relevant parts of the control shall correspond to the requirements from EN ISO 13849-1. — Non-contact protective device as closing edge protection. — In the case of safety guards that swivel upwards and under which the operator has to enter, the minimum height under the opened guard shall be 1 800 mm. Impact edges and corners may not have sharp edges. — Information in the instruction handbook: The manufacturer shall describe the safety working procedures which the operator has to follow in the instruction handbook. These methods of working shall be a component of the training that the operator shall fulfil. 5.2.5 Zone 4 – Blade protection 5.2.5.1 General Cutting tools have to be removed periodically. Cutting tools are sharp and special protective measures shall be taken. For such blades, designers shall provide means of attaching a tool to the blade to avoid hand contact: and a box, or surround guard, to protect against the sharp edges of the blade during handling and transportation. Explanations on the use of these protective means shall be included in the instruction handbook. Injuries due to cutting or piercing when working with the blade or when the blade is stationary shall be prevented. This is achieved by e.g. the following measures: — A blade protection shall be used for installation, removal and transport of the blade. — The manufacturer shall describe the residual risks when working with the blade and during all work in the area of the blade, especially during cleaning and maintenance, in the instruction handbook. The use and handling of the blade protection shall be described in the instruction handbook. SIST EN 13870:2015
Data on the safe storage, transport, maintenance, cleaning and use of the blades shall be contained in the instruction handbook. — The stationary blade may not move unintentionally when the housing is open and closed, e.g. by a braking device. 5.2.5.2 Cutting device and automatic loading Access into the active area of the powered blade shall be prevented during cutting operation and during automatic loading. This is achieved by e.g. the following measures: — The inlet-side access shall be prevented by the guards (e.g. loading protection hood, loading protection door). — For safety requirements, see 5.2.2.1 Zone 1. — The movable guards shall be locked with the machine drive. The interlocks shall correspond to the requirements from 5.2.12. — The inlet-side access is prevented by non-contact protective device, e.g. active optoelectronic protective device (AOPD). These shall correspond to EN ISO 13855. — The blade shall be installed in a blade housing with an interlocked blade protection hood. The interlocks shall correspond to the requirements from 5.2.12. — The outlet-side access into the active range of the blade shall be prevented by guards. — Requirements for the guards, see 5.2.3 Zone 2. — The movable guards shall be locked with the machine drive. The interlocks shall correspond to the requirements from 5.2.12. 5.2.5.3 Manual loading for powered blade Access to the active area of the powered blade shall be prevented during manual loading. This is achieved by e.g. the following measures: — A locking slide separates the blade from the feed area during loading. The locking slide may only be opened if the loading protection hood/loading protection door is closed. The loading protection hood/loading protection door can only be opened if the locking slide is closed. The interlock shall correspond to the requirements of EN ISO 14119:2013. — Openings in the locking slide (e.g. for hold-down unit) shall correspond to the requirements of EN ISO 13857:2008, Table 4. 5.2.5.4 Manual loading while blade is stationary Access to the active area of the stationary blade shall be prevented during manual loading. This is achieved by e.g. the following measures: — The blade shall be stopped with the normal stopping device before manual loading. The blade shall come to a standstill in a position in which direct access to the cutter is not possible. The requirements of EN ISO 13857:2008 apply in respect to this.
