4 Safety requirements and/or protective/risk reduction measures
4.1 General
4.1.1 Feeding machinery and continuous handling equipment shall comply with the requirements of EN 1009-1:2020, as far as not modified or replaced by the requirements of this part.
4.1.2 To avoid overflow, feed bin design for feeders shall consider the size of the feeding equipment, e.g. trucks, shovels or similar to be used. Especially at the feed and transfer points, guide plates or similar means shall be provided to prevent material from overflowing and falling down. If necessary, fixed guards as specified In EN 1009-1:2020,4.11.2 shall be located around the hopper to prevent access.
Feedrng equipment provides a free passage for material to be passed to the next stage of the processing plant. If this free passage can be blocked by a particularly large piece of rock or stone, then suitable clearance methods and equipment shall be provided to ensure the operator does not have cause to approach the feeder or associated equipment whilst it is in operation. The material guides shall be designed In such a way that material blockage and material accumulation are minimized (see also 6.3). The manufacturer shall define provisions and/or methods for clearing of the obstruction in such a manner that danger to personnel Is kept to a minhrnum
4.1.3 When the feeding equipment gets blocked by material and it is necessary for the operators to enter the machine, means shall be provided to prevent the operator falling into the associated machine or Into a chute according to EN 1009-1:2020,4.4.
4.1.4 Where a feed device has been paused as part of the normal operation of the plant (autonomous or manual control of the feed process), no restart delay or warning is required when the device autonomously restarts, provided that the plant itself has not been stopped This does not apply to Bucket elevators, swivelling conveyors. floating conveyors and screw conveyors
4.2 VIbrating feeders
Access to crushing points shall be prevented by guards as specified in EN 1009-1:2020, 4.11 or safety distances shall be provided according to EN ISO 13854:2019.
The residual hazards shall be identified with safety labels.
If the feeder is located under stockpile, bins or glory hole, in order to reduce burying hazard during maintenance, means shall be provided to stop material feeding and adjust the flow (e.g. Inserting bars, closing gate or flap).
4.3 Reciprocating plate feeders
4.3.1. Guards In accordance with EN 1009-1:2020,4.11 shall be provided for the crushing or shearing points due to the oscillating movement of the plate feeder (e.g. at the transfer points).
4.3.2 For inclined reciprocating plate feeders, means for locking against incidental moving during maintenance shall be provided.
If the feeder Is located under stockpile, bins or glory hole. In order to reduce burying hazard during maintenance, means shall be provided to stop material feeding and adjust the flow (e.g. inserting bars, closing gate or flap).
4.4 Apron feeder
4.4.1 Particularly the design of the transporting section of inclined apron feeders shall consider that material rolling back cannot get outside the Feeder or Its hoppers/chutes.
4.4.2 During maintenance work, the apron feeder deck shall be protected against reverse motion, at least by means of a back stop.
4.4.3 It shall be ensured that the moving parts cannot be reached by the operator by guards complying with EN 1009-1:2020. 4.11.
If the feeder Is located under stockpile. bins or glory hole. In order to reduce burying hazard during maintenance, means shall be provided to stop material feeding and adjust the flow (e.g. inserting bars, closing gate or flap).
