locations or facilities designed and suitable for recurring access to continuous handling equipment for operating, control, inspection, maintenance and repair purposes and at or via which persons can approach the continuous handling equipment without particular physical exertion or risk (climbing over/underneath), or move along, over or under it 4 List of significant hazards 4.1 General This clause lists all the significant hazards, dangerous situations and circumstances which have been identified in a risk assessment as relevant for the area defined in the scope and require definition in order to eliminate or reduce the risk. A complete list of all the hazards mentioned in EN 1050 is given in Annex A. Their precise descriptions form the basis for the safety precautions stipulated in clause 5. Before applying this standard, it is necessary to consider the hazards relating to the continuous handling equipment and its planned use in order to ensure that all hazards have been identified. 4.2 Mechanical hazards 4.2.1 Crushing and shearing Crushing and shearing may occur where components move towards or closely past one another. 4.2.2 Entanglement, drawing-in and trapping Hazards generated by the entanglement, drawing-in and trapping of persons, body parts or clothing may arise in proximity to circulating belts, pulleys, idlers, shafts and couplings, chains and sprockets or other circulating or rotating components. Trapping and entanglement hazards occur in particular due to protruding sharp edges, teeth, bolts/screws, lubricating nipples and other projecting parts or rough surfaces of circulating or rotating components. Belt conveyors involve drawing-in hazards, in particular at nip points where the belt runs onto pulleys or idlers, or narrow passages are formed between the belt and fixed parts, and where persons' body parts or limbs may be drawn in. It shall be remembered that belt conveyors with reversible direction of movement have two in-running nips at each pulley, idler or narrow passage. 4.2.3 Stability Stability may be lost due to: a) overloading; b) insufficient anchoring; SIST EN 14658:2005+A1:2010
4.2.4 Hazards generated by fracturing and rupturing during operation Fracturing of the drum shaft (e.g. following bearing damage) may cause the belt drive to fall off, generating a hazard for equipment parts or persons. Rupturing of pressurized hydraulic lines can generate a hazard for equipment parts or persons. 4.2.5 Hazards generated by slipping, tripping and falling Hazards may occur in the form of slipping, tripping and falling, e.g. as a result of poorly designed walkways. 4.3 Electrical equipment hazards Hazards may occur due to: a) direct contact with electrically active parts as a result of damage to insulation or sheathing; b) faulty disconnection of electrical power; c) ingress of handled material or moisture into electrical systems. 4.4 Thermal hazards Hazards may arise due to:
a) heat generated by the movement of defective components of the continuous handling equipment; b) heat generated by a relative movement (e.g. slip) between components of the continuous handling equipment; c) the temperature of the handled material. 4.5 Radiation hazards Continuous handling equipment may also use radiating devices (e.g. laser measuring instruments, X-ray equipment or measuring apparatus operating with radioactive beams) for measuring and monitoring purposes The operation of such devices may generate hazards. 4.6 Hazards due to handled materials Hazards may arise due to the spillage, caking, ejection or falling-off of handled materials or due to dust.
4.7 Hazards due to neglect of ergonomic principles The neglect of ergonomic principles may lead to persons having to work in an unhealthy posture at continuous handling equipment (e.g. in the control station), involving excessive physical effort or mental overload or underload. SIST EN 14658:2005+A1:2010
Access to the space beneath gravity take-up devices is permitted for repair purposes only. If the lowermost part of the gravity take-up device is accessible, a safeguard is required as protection against the mass falling. The safeguard shall be effective during access beneath the gravity take-up device. 5.2.2 Entanglement, drawing-in and trapping In working areas, in-running nips and other points generating hazards shall be fitted with guards in accordance with EN 953 or the safety distances shall be observed in accordance with EN 294. 5.2.3 Stability The manufacturer of the continuous handling equipment shall ensure through suitable design that no loss of stability occurs due to overloading, e.g. as a result of overfilling the conveying element.
To avoid overloading with the handled material, a conveying element cross-section filled to the edges in addition to an overlying triangular cross-section corresponding to the angle of repose of the handled material shall be assumed in the design calculation of the continuous handling equipment. Furthermore, the manufacturer shall provide devices to be able to anchor the continuous handling equipment or its components so that any unintended movements, e.g. as a result of the forces acting in the conveying element, are precluded. Where unintended movements of the continuous handling equipment may occur due to excessively strong wind, the manufacturer shall provide devices to anchor the continuous handling equipment in place. In the case of railbound, mobile continuous handling equipment, devices shall be provided which reliably prevent derailment or the continuous handling equipment shall be designed so that its stability is not impaired by derailment. 5.2.4 Hazards generated by fracturing and rupturing during operation Where belt drives arranged on the drum shaft may generate hazards for equipment parts or persons as a result of the drum shaft fracturing, arresting devices shall be provided which prevent the belt drive from falling off. The arresting devices shall withstand the dynamic loads occurring during such falling-off, the latter being dependent on the belt drive mass, height of fall and arresting device rigidity. Pressure and drain lines of hydraulic cylinders holding continuous handling equipment components in position during operation shall be provided with a pipe rupture check valve. 5.2.5 Access 5.2.5.1 Access in general
EN ISO 14122-1, EN ISO 14122-2, EN ISO 14122-3 and EN ISO 14122-4 shall generally be applicable.
Continuous handling equipment shall have emergency stop devices that conform to stop category 0 or 1 in accordance with EN 418.
Exceptions from this are belt conveyors used in opencast mining, unless they are an integral part of a continuous handling equipment system. An emergency stop device cannot reduce a hazard for belt conveyors in opencast mining. These shall have local stop devices that meet the requirements of 5.3.3.2. 5.3.3.2 Stop device requirements
Stop devices for deactivation of the continuous handling equipment shall be installed in the areas provided for local inspection during operation. Pull-cord operated switches or push-button operated switches may be used as operating elements for the stop devices. It is also possible to use other solutions instead of pull-cord or push-button operated switches that ensure equal safety The spacing between the stop devices shall not be more than 150 m. Furthermore, stop devices shall be provided at all locations from which the belt conveyor can be activated. Where pull-cord systems are used, the pull cord shall be designed as a corrosion-proof and adequately dimensioned wire rope, in keeping with the expected ambient conditions. Upon actuation of a stop device, the stopping process shall be initiated immediately; in the case of linked continuous handling equipment units, delayed stopping of the downstream units receiving material is permissible to avoid spillage. Stopping shall take place in controlled or uncontrolled mode, with or without power disconnection. Unauthorized restarting of the continuous handling equipment shall not be possible after actuation of a stop device. Spillage conveyors that form part of a belt conveyor and can only be started up together with the belt conveyor in interlocking operating mode do not require a stop device of their own if, in the unlocked operating mode, the spillage conveyor can be overlooked from the control station. Drives of associated equipment shall have local control devices for their activation/deactivation. The control devices shall conform to the requirements applicable to stop devices, and the operating element shall remain in the "off" position until it is intentionally returned to the "on" position.
The unlocking of one or more continuous handling equipment unit(s) shall not render the stop devices ineffective.
5.3.4 Unexpected or unintended start-up It shall be possible to safeguard continuous handling equipment against unauthorized start-up in accordance with the requirements of EN 1037. It shall be ensured that the stop devices are clearly identified, that they clearly indicate the switching position, and that it is clearly defined in which part of the equipment the disconnection is effective. For this purpose, continuous handling equipment shall be fitted with devices allowing all-pole interruption. Appropriate arrangements to preclude unintended start-up shall be provided. Where the device is freely accessible, it shall have a locking mechanism. If it is located in a closed electrical operating area, warning signs will be sufficient. A stop device and, if required, a brake system and/or arresting device shall be provided to prevent the risk of any unforeseen start-up during maintenance and cleaning activities. SIST EN 14658:2005+A1:2010
The manufacturer shall take into consideration the characteristics of the materials handled. The occurrence of spillage and caking shall be taken into account when designing and specifying the continuous handling equipment. In working areas where there is the risk of handled material being ejected from the sides and this cannot be avoided through primary measures such as chuting, deflector guides or rope arrangements, for example, secondary precautions shall be taken, such as protective roofing or catch nets. The hazardous areas shall be identified, taking into consideration the properties of the handled material (granular material, lumps or similar), the conveying speed and inclination of the conveyor. At passageways and thoroughfares, precautions in the form of protective roofing or catch nets, for example, shall be taken to safeguard against falling materials. Spillage from linked continuous handling equipment shall be prevented by means of interlocking operation. The removal of spillage and caking shall be possible without any risk, particularly in the feed hoppers. Where hazards are generated by dust, appropriate technical and/or organizational measures shall ensure that the values admissible for workplaces are not exceeded. 5.7 Hazards due to neglect of ergonomic principles Continuous handling equipment shall be designed and constructed in such a way as to avoid inadmissible physical stress during i
