Introduction This European Standard is a type C standard as stated in EN ISO 12100-1. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. Where 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. Lifting bag systems are used by Fire and Rescue Services principally to facilitate the release of persons trapped following accidents involving vehicles, heavy machinery, collapsed buildings, collapsed trenches, fallen trees and other natural objects. Lifting bag systems are generally used in conjunction with other means to support or stabilise the load being moved, for example, blocks, chocks and props. When compiling this European Standard, it was assumed that: a) the manufacturer will design and/or use components in accordance with the usual engineering practise and calculation codes, including all failure modes; b) only trained and competent persons whilst wearing suitable gloves, will use and operate the machinery; c) the working place is adequately lit; d) negotiations occur between the manufacturer and the purchaser concerning particular conditions for the use and places of use for the machinery related to health and safety, which are not within the limits of the scope of this European Standard.

1 Scope This European Standard specifies requirements for lifting bag systems, where intended operation is inflation by compressed air and used primarily by fire and rescue services. This European Standard applies to lifting bag systems including some or all of the following components:  hose assemblies and couplings;  regulators;  control devices;  pressure indicators;  safety valves;  lifting bags. This European Standard applies to lifting bag systems intended for operation under ambient temperatures between -20 °C and 55 °C. This European Standard deals with all significant hazards, hazardous situations and events during the commissioning, operation and maintenance arising from a lifting bag system when it is used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4). This European Standard specifies minimum performance requirements and test methods for lifting bag systems. This European Standard does not establish the additional requirements for: a) operation in severe conditions ( e.g. extreme environmental conditions such as: temperatures outside the range from -20 °C to + 55 °C, corrosive environment, tropical environment, contaminating environments, strong magnetic fields, potentially explosive atmospheres); NOTE 1 If use of the lifting bag system is foreseen in severe conditions, this should be agreed between the purchaser and the manufacturer at the time of ordering. In this case an additional risk analysis should be carried out. Additional measures and additional information for use may be necessary. b) risk directly arising from any means for handling or transportation of the lifting bag system by equipment other than that designed as part of the lifting bag; c) lifting bag systems manufactured for specialized use, e.g. the lifting of persons or heavy recovery where exceptional stroke movement is required; d) any hazard arising from the source of compressed air, except where this is a manually operated air pump. NOTE 2 Where the source is from an air compressor or from a pressurised cylinder or other similar source, it is assumed that the source conforms to an appropriate European Standard or legislation. This European Standard is not dealing with noise, as it is not considered to be a significant hazard. This European Standard is not applicable to lifting bag systems which are manufactured before the date of its publication by CEN.

In addition, the system shall be designed according to the principles of EN ISO 12100-2 for hazards relevant but not significant, which are not dealt with by this document (e.g. sharp edges and noise). NOTE For hazards which are to be reduced by the application of a B-level standard such as EN 894 (all parts), the manufacturer should carry out a risk assessment to establish the requirements of the type B-standard which are to be applied. This specific risk assessment should be part of the general risk assessment of the machine. Where the means of reducing the risk is by a safe system of working the lifting bag equipment, the manufacturer shall include in the Information for Use details of the system and of the elements of training required by the operating personnel (see Clause 7 and Annex A). 5.2 Complete lifting bag system 5.2.1 A lifting bag system (see Figure B.1) shall include the following components:  hose and/or hose assemblies;  regulator;  control device for each lifting bag;  pressure indicators for each lifting bag;  safety valve for each lifting bag;  lifting bag(s). 5.2.2 Components of a lifting bag system as shown in Figure B.1 shall be designed only to fit mating components that are intended for use with the same allowable pressure. 5.2.3 All components in the system shall be designed to mitigate unintentional hazardous movement due to airflow: e.g. ‘snaking’. 5.2.4 The complete lifting bag system shall be capable of being operated within the ambient temperature range of –20 °C to + 55 °C. 5.3 Hose assemblies and couplings 5.3.1 Rubber hoses shall conform to EN ISO 2398 and plastic hoses shall conform to EN ISO 5774. 5.3.2 Hose assemblies shall conform to EN ISO 7751. 5.3.3 At a temperature of (-20 ± 2) °C, hoses shall achieve a bend radius of 75 mm, or less. 5.3.4 Hose fittings and quick action couplings shall withstand an axial pulling force of at least 1 000 N when the internal pressure is at atmospheric pressure and when at allowable pressure.
