BS EN 13731:2007:2008 Edition

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
