BS EN 115-2:2010EN 115-2:2010 (E) 5 Introduction Background of this standard More than 75 000 escalators and moving walks are in use today in the European Unio

22、n (EU) and European free Trade Association (EFTA) and almost 50 % were installed more than 20 years ago. However, this standard compares the safety level of escalators and moving walks installed after 1970 with those within EN 115-1:2008. This recognises that the first attempt to have a common stand

23、ard for escalators and moving walks was the CIRA Recommendation 28 1. Escalators and moving walks were installed to the safety level appropriate at that time. This level is less than todays state of the art for safety. New technologies and social expectations have led to todays state of the art for

24、safety. This has led to the situation today of different levels of safety across Europe causing accidents. However, users and authorised persons expect a common acceptable level of safety. Furthermore the life cycle of escalators and moving walks is longer than most other transportation systems and

25、building equipment, which therefore means that the design, performance and safety can fall behind modern technologies. If all existing escalators and moving walks are not upgraded to todays state of the art of safety the number of injuries will increase (especially in areas which can be accessed by

26、the general public, recognizing the change of behaviour and changing attitudes towards safety in general). If escalators or moving walks were installed before 1970 on the base of manufacturers and national standards or were installed after 1970 but not in accordance with CIRA Recommendation 28, then

27、 they should be the subject of a separate risk assessment in addition to the recommendations of this standard to determine whether a safety upgrade or a full replacement is appropriate. Approach of this standard This standard categorises various hazards and hazardous situations, each of which has be

28、en analysed by a risk assessment (see in particular Annex A); is intended to provide corrective actions to progressively and selectively improve, step by step, the safety of all existing escalators and moving walks towards todays state of the art for safety (see Clause 5); enables each escalator and

29、 moving walk to be audited and safety measures to be identified and implemented in a step by step and selective fashion according to the frequency and severity of any single risk (see Table B.2); lists the high, medium and low risks and corrective actions which can be applied in separate steps in or

30、der to mitigate the risks (see Table B.2). Use of this standard This standard can be used as a guideline for: a) national authorities to determine its own programme of implementation in a step by step process via a filtering process (see Annex A) in a reasonable and practicable1)way based on the lev

31、el of risk (e.g. high, medium, low) and social and economic considerations; 1) “Reasonable and practicable” is defined as follows: “In deciding what is reasonably practicable the seriousness of a risk to injury should be weighted against the difficulty and cost of removing or reducing that risk. Whe

32、re the difficulty and costs are high, and a careful assessment of the risk shows it to be comparatively unimportant, action may not need to be taken. On the other hand where the risk is high, action should be taken at whatever cost.”. BS EN 115-2:2010EN 115-2:2010 (E) 6 b) owners to follow their res

33、ponsibilities according to existing regulations (e.g. use of Work Equipment Directive); c) maintenance companies and/or inspection bodies to inform the owners on the safety level of their installations; d) owners to upgrade the existing escalator or moving walk on a voluntary basis in accordance wit

34、h c) if no regulations exist. In making an audit of an existing escalator or moving walk installation Annex B can be used to identify the hazards and corrective actions in this standard. However, where a hazardous situation is identified which is not covered in this standard a separate risk assessme

35、nt should be made. This risk assessment should be based on ISO 14798 2. BS EN 115-2:2010EN 115-2:2010 (E) 7 1 Scope 1.1 This European Standard gives rules for improving the safety of existing escalators and moving walks with the aim of reaching an equivalent level of safety to that of a newly instal

36、led escalator and moving walk by the application of todays state of the art for safety. NOTE Due to situations such as the existing machine or building designs, it may not be possible in all cases to reach todays state of the art for safety. Nevertheless the objective is to improve the level of safe

37、ty wherever possible. 1.2 This standard includes the improvement of safety of existing escalators and moving walks for: a) users; b) maintenance and inspection personnel; c) persons outside the escalator or moving walk (but in its immediate vicinity); d) authorised persons. 1.3 This standard is not

38、applicable to: a) safety during transport, installation, repairs and dismantling of escalators and moving walks; b) spiral escalators; c) accelerating moving walks. However, this standard can usefully be taken as a reference basis. 2 Normative references The following referenced documents are indisp
