21、Nov 17 08:56:57 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN 1794-2:2003 (E) 4 Introduction While performing their primary function, road traffic noise reducing devices should not pose hazards to road users or other people in the vicinity or to the environment at large. Noise reducing devices shoul
22、d not assist the spread of fire from adjacent verges or nearby land. Fire resistance in accordance with particular standards can in addition be required to minimise risk to adjacent premises, or to road users in confined corridors. Noise reducing devices should not reflect light in such a way as to
23、prejudice road safety. They should be made from materials which do not emit noxious fumes or leachates as the result of natural or industrial processes, or as the result of fire. Noise reducing devices should allow a means of escape by road users and access by operatives in the event of an emergency
24、. Noise reducing devices are not in general expected to resist the impact of vehicles, but designers can need information about the consequences of such impact load to establish the requirements for protection of road users and passers by.
