4 List of significant hazards
This clause contains all the significant hazards, hazardous situations and events identified by risk assessment as significant for this type of machinery and which require measures to eliminate or reduce the risk associated with the identified hazards (see Table 1).
5 Safety and hygiene requirements and/or protective measures E
5.1 General
Cubes cutting machines shall comply with the safety requirements and/or protective measures of this clause and Annex C of this document.
In addition, they 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).
The safety related parts of the control system shall present at least a performance level “c” in accordance with
EN ISO 13849-1.
5.2 Mechanical hazards
5.2.1 General
The interlocking devices shall be built inside the machine housing and shall comply with EN ISO 14119:2013, 4.2 and Clause 7.
After activating an interlocking device the stopping time of the blade shall be ≤ 0,15 s.Hazardous after-run of tools shall be prevented by braking devices or other solutions with equivalent effect. Braking devices shall become automatically effective upon switching off the drive and in the event of a voltage failure and upon opening of the protective devices.
In the instruction handbook, the manufacturer shall indicate the daily verification of the interlocking device. Fixing systems for fixed guards or for demountable parts of the machine casing (i.e. designed as fixed guards) shall remain attached to the guards or to the machine when the guards are removed.
5.2.2 Measures on cubes cutting machines with a forward feed plunger, a lattice and sickle blade and loading by hand
5.2.2.1 Zone I — Feed intake chamber (magazine) with forward feed plunger, feed intake hopper with closure gate, feed conveyor, nip roller
Access shall be prevented either by a movable guard (e.g. restrictor plate, lid), interlocked according to 5.2.1 or shall be secured by a non-detachable restrictor plate or adequate safety distances and design as described in 5.2.3.3. Taking into account the specific technical constraints (high loading frequencies), the movable guard (lid) can be designed as a control guard according to EN ISO 12100:2010, 3.27.6. Openings in the guard (e.g. restrictor plate, lid) may have a diameter D≤ 52 mm for L≥ 120 mm. The dimensions and arrangements of the guard shall be according to Figure 12. Fastening of the nondetachable restrictor plate shall be according to EN 953.DIN EN 13871 pdf download.
