EN 15095:2007+A1:2008 (E) 5 Introduction This standard is a type C standard as stated in EN ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and hazardous events are covered are indicated in the scope of this standard. For machines designed and built according to the specifications of this Type C Standard the following applies: "When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards for machines that have been designed and built according to the provisions of this type C standard."
When this standard was prepared it was assumed that:  only trained staff would operate, repair or maintain the machine;  components without special requirements are 1) sized in accordance with good engineering practice and methods of calculation including all types of failure; 2) correctly constructed mechanically and electrically; 3) made of materials of adequate loading capacity and of suitable quality; 4) made of materials that are fit for that purpose.  components are kept in a good repair and operating condition so that the required characteristics can be maintained in spite of wear and tear;  sizing of load bearing parts ensures safe operation of the machine in a loading range from 0 % to 100 % of the nominal capacity and during testing conditions if applicable;  details of particular conditions of use and the installation site are agreed between user and manufacturer;  working area is adequately illuminated;  installation site permits safe operation of the machine. SIST EN 15095:2008+A1:2009



EN 15095:2007+A1:2008 (E) 6 1 Scope 1.1 This European Standard deals with the safety requirements for the following types of power-operated storage equipment:  storage carousels;  storage lifts;  mobile shelving, pallet racking and cantilever racking with the objective of eliminating or minimising the hazards described in Clause 4. These hazards can arise during installation, starting up, operation, maintenance, testing and dismantling of the equipment. 1.2 It is essential that the safety requirements and/or measures taken in this standard be applied to storage equipment which operates indoors. Under difficult conditions, it is essential that additional hazard analysis and safety measures be taken into account, e. g. outdoor conditions, freezer applications, high temperatures, corrosive environment, strong magnetic fields, risk of explosive atmosphere, radioactive conditions, storage goods which due to their nature could generate hazardous situations (e. g. molten metal, acids/alkalis, fragile goods or explosives), effects of earthquakes and also contact with food.
1.3 Examples of power-operated storage equipment to which this standard applies are shown in Annex A. 1.4 With regard to buildings and parts of buildings, this standard applies only insofar that an assessment regarding hazards and risks in connection with interfaces to the storage equipment is carried out. 1.5 Storage equipment whose only power source is directly used human labour or gravity are excluded from the scope of application of this standard. 1.6 Power-operated storage equipment or parts of them do not fall under the regulations for passenger lifts. They are intended to handle and store goods. They are not intended to transport passengers under normal use (except for maintenance) and therefore not considered to be lifts (elevators).
1.7 This standard does not take hazards into account, which arise from noisy environments or environments subject to electromagnetic interference outside the range quoted in EN 61000-6-2. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies.

The in-built lift unit carries the load carriers (e.g. storage containers) from an access opening to storage locations in a racking tower, or from a storage location to an access opening. Storage lifts can have one or more access openings on one or more levels (see Figure A.3) 3.3 mobile shelving mobile shelving comprises a series of hand loaded adjustable load carrying surfaces (shelves) supported by upright frames all of which is in turn fixed to a movable base unit. This base unit is supported on wheels mounted in the base unit which run on rails mounted in or on the floor. The system is designed to be loaded by hand with multiple loads all of which are substantially less than the total carrying capacity of the shelf. The system is not designed to be loaded or unloaded by mechanical equipment (see Figure A.4) 3.4 mobile racking mobile racking comprises a skeleton framework of fixed or adjustable design supporting unit loads generally without the use of shelves. This skeleton framework is in turn fixed to movable base units supported on wheels mounted in the base unit, which run on rails mounted in the floor. The system is designed for the storage of unit loads where loading or unloading is generally by mechanical means (see Figure A.5)

EN 15095:2007+A1:2008 (E) 10 4.1.7 Hazards arising from slipping, stumbling or falling These hazards can occur, for example, due to the construction of flooring in the area of mobile storage equipment. 4.1.8 Hazards arising from potential lack of tipping stability These hazards can occur for example due to incorrect motor power/braking, inappropriate wheel carriage design. 4.2 Electrical power hazards Electrical hazards can occur for example through:  direct or indirect contact with live parts as a consequence of damage to the insulation or ingress of dirt, water etc.;  incorrect isolation of power supply to the system or parts of the system due to inappropriate circuit design. 4.3 Hazards through ignoring ergonomic principles in machine design These hazards can arise for example, as a result of:  badly arranged operating equipment and working places;  excessive strain on operating staff in regard to speed and energy requirements. 4.4 Hazards caused through failure of power supply, failure of machine parts or other functional faults Hazards caused by failure of the power supply can occur when storage equipment or storage goods run backwards or fall unintentionally. Hazards caused by failure of machine parts, such as the failure of suspension chains. 4.5 Hazards arising from inappropriate design or failure of safety systems These hazards can, for example, occur through:  unfavourable positioning of emergency shutdown devices;  inappropriate positioning of safety related devices;  inappropriate choice of safety devices;  missing or faulty interlocking of maintenance access covers with the drive. 4.6 Hazards caused through electromagnetic influences These hazards can, for example, occur through:  inappropriate design of electrical control system;  inappropriate selection of electrical subassemblies.
