— parts of machines;
— tools of machines or parts of tools;
— workpieces or parts of workpieces or
— materials being processed.
NOTE Danger points can exist, for example, on gear, chain and worm drives, V-belt, flat belt, cord and rope drives, pulling and supporting elements on continuous conveyors, spoke wheels and fly wheels, shafts and shaft ends, rollers, slides, push rods and similar parts, tools and clamping devices. Particular points of danger are:  crushing and shearing points;  trapping points;

a) two counter-rotating rollers, powered or non-powered; b) one rotating roller and an adjacent fixed part of the machine; c) rollers rotating and conveyer belts in the same direction, but with different peripheral speeds or surface properties (friction); d) guide roller and driving belt, conveyor belt and possibly the web (see Figure 1). Inrunning nips also exist on non-powered riding rollers (guide rollers) which are driven by the movement of the web. This hazard may depend on a number of factors, e.g. type and strength of material, wrapping angle, web speed, inertia. - Figure 1 — Examples of inrunning nips 3.3 integrated pile lifting and lowering devices devices integrated into sheet and blank feeders or deliveries for lifting and lowering the sheet pile 3.4 format size maximum size of blanks (maximum length times maximum width) that can be printed or converted by the machine 3.5 routine and regular access access to a danger point required for production reasons after each tool closing movement 3.6 web-type materials webs of paper, board, foil or similar material which is to be handled or processed

5 Safety 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 for hazards relevant but not significant, which are not dealt with by this document (e. g. sharp edges of the machine frame). 5.2 Requirements common to printing and paper converting machines 5.2.1 Safeguarding of danger points 5.2.1.1 Inrunning nips on cylinders, rollers, drums, rolls and similar parts shall be safeguarded by guards or by applying the safety distances specified in EN 349:1993. On guide rollers, the safety distance specified for the arm is considered to be sufficient where risk assessment has determined that whole-body or head access cannot be expected. Guards shall be designed as follows: a) as guards without openings or with openings for feeding the material (for example sheets, blanks, webs, work pieces). The safety distances shall be established in relation to the width of the opening in accordance with EN 294:1992 (see Figure 2).
These guards shall be interlocked with the dangerous movements in accordance with 5.2.2 or they shall be fixed to the machine. When the interlocking guard is open, one of the measures set out in 5.2.3 shall become effective.

Figure 2 — Safeguarding of inrunning nips b) on smooth-surface rollers or cylinders as fixed nip bars extending across the entire working width, designed in suitable sections. The clearance between the bar and the respective machine part, for example, cylinders, rollers with a smooth surface etc., shall not exceed 6 mm (see Figure 3).
Figure 3 — Safeguarding an inrunning nip by means of a fixed nip bar 5.2.1.2 The use of trip devices for safeguarding inrunning nips shall be permitted only if the condition defined in 5.2.10.2 is satisfied. 5.2.1.3 Linear movements are considered to be sufficiently safe if the maximum distance between moving part and fixed part does not exceed 4 mm.

Figure 4 — Example of a linear movement on a plate clamping device 5.2.1.4 On machines which travel under power, the crushing points between wheels and floor shall be safeguarded. Safeguarding of crushing points is achieved, for example, by providing foot guards fixed such that there is a distance of no more than 15 mm between the runway and the lower edge of the guard. 5.2.1.5 Handwheels and cranks shall be so designed that they do not automatically rotate when the machine operates at production speed. This is achieved, for example, where handwheels and cranks are decoupled by pressure springs during the production run. 5.2.1.6 Where machines with movable parts are used in the workroom, the instruction handbook shall require users to erect machines in such a way that the hazard of crushing of persons between movable machine parts and the building is prevented. 5.2.2 Guards and interlocks
5.2.2.1 Guards shall satisfy the requirements of EN 953:1997. Interlocking shall satisfy the requirements of clauses 5 and 6 of EN 1088:1995. Stopping times vary with the type of machine used, but should be as short as possible. For interlocking, see 5.2.11 (safety position switches with approach reaction) and 5.2.6 (control systems). 5.2.2.2 For fence-type enclosures, the safety distances according to EN 294:1992 apply. A further requirement is that the distance between the floor and lower edge of the fence does not exceed 200 mm and between the floor and upper edge is at least 1,4 m. 5.2.2.3 Guards and access doors in enclosures which are opened or removed frequently in the production process or for setting-up operations shall be interlocked with the hazardous movements. Guards which do not have to be opened frequently shall be fixed in such a way that their removal necessitates the use of tools. These guards may also be interlocked with the hazardous movements.

5.2.3.1 Where accessible danger zones cannot be observed from positions from which hazardous movements can be started, one of the following requirements shall be satisfied:  where accessible danger zones are safeguarded by a fence-type enclosure, it shall not be possible for the person(s) within the enclosure to close the interlocking access gate or an additional control device shall be provided outside the enclosure in such a position that it cannot be actuated from the inside. Any hazardous movement shall be permitted only after the access door has been closed and the control device been actuated;  where accessible danger zones are safeguarded by means of ESPDs, an additional control element shall be provided outside the danger zone that cannot be reached from any position in the danger zone. Provisions shall be made that the hazardous movement can only be started after the person has actuated the additional control element. 5.2.3.2 When the interlocking guard is opened or removed or if a person has entered the danger zone and there are danger points unprotected, it shall only be possible to start a machine by means of
a) Hold-to-run control devices

Any two-hand control device shall satisfy the requirements defined in 5.2.8. The stopping path shall be as short as technically feasible.
Starting the machine in the hold-to-run mode after opening an interlocking guard may be done without operating a selector switch, if production operation during hold-to-run control is positively prevented by the interlocking device. A selector switch is required for machines which allow two modes of hold-to-run control (hold-to-run control with one actuator and two-hand control). b) Manual operation Devices which allow manual operation of the machine or parts of the machine shall be designed so that persons are not exposed to danger.
5.2.3.3 From the place of operation of the hold-to-run control, it shall be possible to observe the danger points and danger zones. 5.2.3.4 Where hold-to-run controls are being used for safeguarding a danger point, starting the machine in the hold-to-run mode after opening the interlocking guard shall only be possible when other interlocking guards outside the area that can be observed by the operator are closed. 5.2.3.5 Safe threading of the web-type material shall be ensured. On power-driven web threading devices, access to danger points shall be prevented by guards.
Access to danger points is considered prevented if, for example,
 on rope-type threading devices, the inrunning nips between threading rope and idler pulley are safeguarded. Safeguarding may include the provision, on the outside of the pulleys, of a fixed disc, the radius of which is at least 120 mm larger than that of the pulley,  on power-driven bar-type threading devices with transport chains, the inrunning nips between chains and chain wheels are provided with guards filling the inrunning nips as far as possible,  threading is carried out under hold-to-run control with speed limitation. 5.2.4 Explosion prevention and protection 5.2.4.1 All electrical and non-electrical equipment and components intended for use in potentially explosive atmospheres shall be designed and constructed according to good engineering practice and conform to the required categories for group II equipment to ensure avoidance of any ignition source as specified in 5.3 of EN 1127-1:1997. To classify the category of the equipment, it shall be subjected to an ignition hazard assessment in accordance with 5.2 of EN 13463-1:2001. 5.2.4.2 Explosion prevention and protection is not required for machinery where there are no flammable liquids with a flash point below 55 °C being used and no flammable liquids are sprayed or heated to a temperature above flash point under operating conditions. All other machinery shall be designed to satisfy the requirements specified in EN 1127-1:1997 for the zones described in Annex A.
