BS EN 16704-2-2:2016

This European Standard deals with requirements for barriers to give users the possibility to prevent workers 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 demarcation line) where a person would enter the danger zone. For combinations of barriers and TWS see also EN16704‑2‑1:2016 . 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. EN16704‑1 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 safety 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 negotiation between the user and the manufacturer; electrical hazards by different potential of different electrified circuits.
