24、IN EN 16704-2-2:2017-03 4 Introduction The purpose of this standard is to define and harmonize requirements for barriers to separate working zone and danger zone and to prevent workers from entering the danger zone unintentionally. The purpose of this standard is not to define requirements: for stru

25、ctural separation to provide safe train operation in the area of a work site(1); for structural separation to provide safety on a work site during train operation(2). NOTE Examples for exclusions: (1) In case of crane operation on a work site the crane arm could hit or even intrude into the gauge of

26、 an open track and endanger the safety of train operation. (2) A barrier does not protect workers from items falling from passing trains. EN 16704-2-2:2016 (E) DIN EN 16704-2-2:2017-03 5 1 Scope This European Standard deals with requirements for barriers to give users the possibility to prevent work

27、ers from entering the danger zone unintentionally by the use of such barriers. This standard defines minimum requirements and test procedures for these barriers concerning the dimensions, the stability and electrical properties. This standard also gives recommendations for the marking (visual demarc

28、ation line) where a person would enter the danger zone. For combinations of barriers and TWS see also EN 16704-2-1:2016. This standard contains references to electrical hazards from third rail systems. NOTE Urban rail systems do have the same situations but may have other individual track gauges. EN

29、 167041 does not cover Urban rail systems. The use of barriers as a safety measure has the same intention independently of the kind of railway system. This standard in particular does not deal with: risk assessment for safety protection on the track during work; hierarchy of safety measure for safet

30、y protection on the track during work; safety measure to provide safe working and safe train operation in the area of a work site; national safety regulations to plan and operate barriers in track; safety regulations and additional requirements e.g. due to national or operational rules or negotiatio

31、n between the user and the manufacturer; electrical hazards by different potential of different electrified circuits. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
