4 List of significant hazards Significant hazards found in nonwoven machines which are common with those frequently occurring with other textile machines or with machine elements of other textile machines shall be considered in accordance with ISO 11111-1:2005, Clauses 5 and 6, whenever referred to under the heading “General safety requirements” in Clause 5 of this part of ISO 11111. Significant hazards which are particular to nonwoven machines are considered as “Specific hazards” in Clause 5 of this part of ISO 11111. Before using this part of ISO 11111, it is important to carry out a check to ascertain that the specific machine has the significant hazards identified. NOTE The significant hazards of nonwoven machines are always considered in conjunction with safety requirements. 5 Significant hazards and corresponding safety requirements and/or measures 5.1 General Machinery shall conform to the safety requirements of ISO 11111-1:2005, Clauses 5 and 6, whenever referred to under the heading “General safety requirements” of this Clause 5 and shall conform to the additional “Specific safety requirements” of this Clause 5. 5.2 Opening, cleaning, blending machines The safety requirements and/or measures shall be in accordance with ISO 11111-2:2005, 5.2. 5.3 Carding machines General safety requirements The safety requirements and/or measures shall be in accordance with ISO 11111-2:2005, 5.5.
Specific hazards Mechanical, from the cross-folder unit, in particular, crushing, shearing impact; from the conveyors, in particular, drawing-in or trapping; from the wheels, in particular, crushing and shearing; from the web compression rollers, in particular, drawing-in and trapping. Specific risks Occasional access during special operation, in particular, to assist movement of the web, leading to a medium probability of severe injury. Specific safety requirements a) Access to the cross-folder unit shall be prevented. Where full-height fence guards (see ISO 11111-1:2005, A.3) are provided to guard the particularly dangerous machine elements of the cards, these shall be extended along the sides of the cross-folder unit and conveyors and shall extend across the end, unless it is guarded by other means. b) Where there are doors in the fence guard between the cross-folder and roller-clearer card sections, these shall be interlocked with guard locking. c) Where openings in the fence guards to allow access to the conveyors to assist movement of the web at start-up (e.g. using long poles) are provided, they shall not allow access to the danger zone for hand or fingers in accordance with ISO 13852. Alternatively, supplementary guards shall be provided within the fence guard to prevent access to drives or other danger zones through the opening (e.g. a tunnel guard may be suitable).
Specific risks Occasional access during normal operation, particularly removal of fibres, and during special operation, particularly cleaning and changing of the needle board, leading to low probability of severe injury. Specific safety requirements a) To prevent access to the area between the stripper plate and the stitch plate, the inlet and outlet side of the needle machine shall be guarded (e.g. by means of trip bars, trip-wires, pressure-sensitive devices or non-mechanically actuated trip devices according to ISO 11111-1:2005, Table 3, interlocked to the drive for the lifter motion of the needle board). b) The openings in the machine side frame at needle board level, which are used when cleaning the needles, shall be guarded by means of doors or panels interlocked with the drive for the lifter motion of the needle board. To reduce the need to move the needle board with the door open, the machine shall be designed such that the needle board comes automatically to a standstill in an open position, or else the needle board shall be moved into an open position, in preparation for access, by a separate control while the door is closed. When the door is open, the needle boards shall be movable to an open position only by means of a handwheel or similar manual device.
