5 Safety requirements and protective measures 5.1 General requirements Storage equipment shall conform to the safety requirements and/or protective measures of this section and also to the requirements of EN ISO 12100-1 and EN ISO 12100-2 concerning relevant but not significant hazards, which are not dealt with in this standard. Storage equipment and their accessories shall be suitable for operation in the intended condition of use in the working environment for which they have been designed.
Care shall be taken to review the safety aspects of the interfaces with other storage products such as mobile and static racking or pedestrian access areas. 5.2 Mechanical hazards 5.2.1 Design and Installation 5.2.1.1 General Storage equipment shall be designed and installed in such a way that it is able to support the load of the storage goods safely when used in a correct manner.
The stability and load carrying capacity shall be sufficient for the operating loads and be established through calculations of the carrying capacity of the load bearing elements or via static load tests.
The intersection between single components shall be co-ordinated (e. g.: connecting forces, -moments and -stiffness's, as well as electrical, pneumatic and hydraulic connections). 5.2.1.2 Installation Storage equipment and their accessories shall be constructed so that they can be safely installed. If necessary anchorage points for safety harnesses shall be provided. Storage equipment shall be aligned vertically to the tolerances specified by the designer and as laid down in the installation instructions.
The maximum deviation from the vertical shall not exceed 1/350 of the height. SIST EN 15095:2008+A1:2009

 only top most storage level is loaded, single sided;  all storage levels are loaded, single sided, with the exception of the level directly supported by the base of the mobile equipment. Pattern loading to check the tipping stability in case of vertical carousels:
 only top most storage level is loaded. For other products stability shall be checked in the worst possible loading condition. 5.2.1.4 Safeguarding against failure of racking The basis of design for steel bases and rack structures will be in accordance with EN 1993-1-1 and EN 1993-1-3 as far as it applies to these structures. Inertia forces due to accidental stop (stopping distance max. 15 mm) have to be considered with a load factor: 1,1. 5.2.1.5 Safeguarding against failure of suspension and drive elements of carousels and storage lifts The storage equipment manufacturer shall have a certificate on chains/ropes/belts (or other) showing the minimum design breaking load of chains/ropes/belts (or other) and refer to that certificate for each purchase. To minimise calculation and validation effort (e. g. wear, and tear, contamination, shock loading during the lifetime of the equipment) it is permitted to use the following simplified methods: a) Vertical carousels The suspension chains shall be designed in accordance with ISO 10823 to withstand, without breaking, 7 times the maximum static force or 5 times the maximum dynamic force occurring during fully loaded operation. For the calculation of the maximum break load is the sum of the load fixed on maximum length of vertical chain segments located over each other mandatory (see Annex E). b) Horizontal carousels No specific condition is required if failure of the drive elements results in a fail-safe condition, otherwise a) applies. c) Storage lifts The suspension chains, ropes, belts and other suspension elements shall be designed to withstand, without breaking, 7 times the maximum static force or 5 times the maximum dynamic load force occurring during fully SIST EN 15095:2008+A1:2009

Storage lifts with a working load limit of 1 000 kg or more shall be provided with an overload protection. 5.2.1.6 Actions (Loads and forces) When verifying the level of safety with regard to stability and failure, the following possible combination of actions shall be considered:  sum of self-weights;  sum of specified imposed loads (e. g. design values for shelf loads and weight of load units);  placement loads, as a consequence of the method of manual or mechanical operating the storage equipment;  inertia forces due to normal stop and emergency stop. The initial non-verticality imperfection may not be regarded as a loading, but shall be treated as an initial property of the structure. Nevertheless it is allowed to take the non-verticality into account as an equivalent horizontal load at each storage level. This imperfection shall be taken into account in the longitudinal as well as in the transversal direction, but not simultaneously. 5.2.1.7 Locks against falling out and/or down Components of storage equipment shall be designed or secured in such a way that they cannot fall out or down (e. g. clipped or hooked-in components, drawers).
5.2.1.8 Deflection The following deflection limits shall be considered for the maximum permissible imposed load, if no specific requirements have to be fulfilled:  steel: span/200;  timber or wood-based: span/150. but taking into account the influence of the load duration according to EN 12369-1. )1()(defkdeflectiontermshortdeflectionFinal+×= where
defk = load duration factor depending on material type and load duration classification 5.2.1.9 Safeguarding hazardous locations Dangerous locations (e. g. crushing, drawing-in, shearing locations) on storage equipment shall be guarded, where safety distances according to !EN ISO 13857" respectively the minimum distances to avoid crushing according to EN 349 are not maintained. If guards are used, they shall be fixed in a reliable manner and of adequate mechanical strength. It shall only be possible to remove them with a tool or they shall be interlocked with the drive.
5.2.1.12 Tripbars
Tripbars shall work over the full length. Limit switches which are operated by the tripbars shall be of a positive operated type and interlocked with the drive so that when they are operated the dangerous movement is safely stopped. Automatic re-starting shall be prevented.
NOTE See EN 1760-2 and EN 50047 for design shapes of position switches. 5.2.2 Carousels 5.2.2.1 Openings 5.2.2.1.1 General To safeguard the operating personnel against dangerous movement of load bearing devices of carousels the following protective measures are necessary. 5.2.2.1.2 Opening for picking
Dangerous areas and shearing points shall be protected e. g. by trip bars, contactless safety devices. 5.2.2.1.3 Carousels with more than one access opening Carousels with more than one access opening shall be fitted with electrically interlocked doors or monitoring elements so that only one access opening can be used at a time. Monitoring elements can be motion sensors, switching mats, light barriers or similar devices.
The monitoring and interlocking elements shall be in compliance with EN ISO 13849-1 as defined after the risk analysis for the whole machine. 5.2.2.1.4 Cladding Covers on Carousels which have to be opened by the operator when dealing with operating faults shall be electrically interlocked with the drive. SIST EN 15095:2008+A1:2009

5.2.2.2.2 Protection against uncontrolled forward and backward motion through uneven loading Generally vertical carousels shall be designed so that unintentional forward and backward movement is prevented effectively, when the highest degree of uneven loading distribution occurs (load difference between front and rear loading planes). For storage units of more than 3 tonnes load capacity devices are permitted which indicate optically or acoustically when the uneven loading distribution has reached the permissible limit and which prevent starting up or interrupt the moving operation in the critical direction when the limit has been exceeded. The correct sequence of loading and unloading shall be described in the operating manual.
For carousels with storage goods of almost the same shape and a complete view into the unit (e. g. carpet display units), it is sufficient to design the drive for the highest permitted degree of uneven loading distribution and to provide definite instructions in the operating manual.
5.2.2.2.3 Protection against items falling off Carousels shall be provided with safety measures against items falling off. Panelling, covering and protection devices shall be adequately dimensioned and secured. Protective measures shall not generate new dangerous locations.
5.2.3 Storage lifts 5.2.3.1 Openings 5.2.3.1.1 Openings for picking Areas where there is a possibility of entanglement or shearing shall be protected either by interlocked doors or light curtains at the outer rim of the picking opening or by means of light curtains at another position together with mechanical design which prevents the occurrence. EXAMPLE The danger of entanglement between a load bearing device and picking opening is avoided, if the picking opening is designed smooth and when the distance between load bearing equipment and picking opening is either less than 5 mm or more than 50 mm. A warning label has to be mounted durable and easy visible at the opening with clear declarations of the risks. It shall be ensured that a load carrier e. g. storage container which is being dealt with at an access opening cannot be called up from a different access opening. 5.2.3.1.2 Opening for maintenance Access openings for maintenance if provided shall be guarded in accordance with EN 953. They shall only be opened with a special tool or shall be interlocked with the electrical drive. 5.2.3.2 Protection against items falling off Storage lifts shall be provided with safety measures against falling items. Panelling, covering and protection devices shall be adequately secured. Protective measures shall not generate new dangerous locations.
50 mm high on all sides;  survival space of 1,5 m height shall be provided;  means shall be provided to anchor the person being transported against a fall. This shall be ensured by anchoring points on the platform;  control equipment on the platform shall have priority over all other control equipment. 5.2.4 Mobile shelving, pallet racking and cantilever racking 5.2.4.1 Floor clearances In order to avoid injury to feet, the distance between the bottom edges of mobile storage equipment (also of safety devices) and the floor shall not exceed 15 mm for:  handloaded mobile shelving equipment; SIST EN 15095:2008+A1:2009
