Together with BS EN 14175-2:2003, BS EN 14175-3:2003, BS EN 14175-4:2004, DD CEN/TS 14175-5:2006, BS EN 14175-6:2006,
3、 BS EN 14175-7:2012, it supersedes BS 7258-1:1994, BS 7258-2:1994, BS 7258-3:1994 and BS 7258-4:1994 which are withdrawn.The UK committee advises that prior to purchasing a fume cupboard, a risk assessment should be performed to assess the risks associated with the substances that are to be manipula
4、ted. This would ensure that the fume cupboard is suitable for its intended purpose and that current exposure limits for toxic substances are not exceeded. It is suggested, therefore, that users may need to draw up a specification appropriate to their particular requirements, within the overall permi
5、ssible limits of this standard and the information on installation included in the National Annex. For users with little experience of purchasing fume cupboards, it may be helpful for trade associations, employers bodies or other organizations associated with a particular activity to give guidance o
6、n a suitable specification.
