适用范围

1 This Part of BS 7258 specifies minimum safety requirements for general purpose laboratory fume cupboards and describes the methods of test to be used to determine their performance. 2 This Part of BS 7258 is not intended to cover fume cupboards for such special applications as carrying out work on radioactive materials, perchloric acid, etc. or for work where large quantities of heat are released. NOTE 1. Large quantities of heat create convection currents that adversely affect performance. This Part of BS 7258 is applicable to fume cupboards for some special applications but such fume cupboards will also have to comply with additional requirements, appropriate to specific hazards of the particular application, which are not covered in this specification. NOTE 2. Attention is drawn to the provisions of the following regulations. a) The Control of Substances Hazardous to Health Regulations 1988 (Statutory Instrument No. 1657)[2] and associated Approved Codes of Practice. Fume cupboards should be regarded as local exhaust ventilation equipment for the purposes of these Regulations. b) The Ionizing Radiations Regulations 1985 (Statutory Instrument No. 1333) [3] made under the Health and Safety at Work etc. Act 1974 and any other subsequent regulations made under that Act. c) Highly Flammable Liquids and Liquefied Petroleum Gases Regulations 1972 (Statutory Instrument No. 917) [4] (which were made under the Factories Act 1961) and in particular Regulation 10(2). Even when the regulations do not apply to particular premises, the standards they describe should be used as a guide. d) The Electricity at Work Regulations 1989 [5]. These regulations may not apply to all premises but the standards described will be a useful guide. 3 This Part of BS 7258 is not applicable to microbiological safety cabinets (see BS 5726). 4 This Part of BS 7258 is not applicable to specially designed fume cupboards of the following kinds: a) 'walk in' fume cupboards; b) recirculating fume cupboards; c) mobile fume cupboards not installed or operated in a manner complying with 3.2 and 3.4 of BS 7258 : Part 2 : 1994; d) fume cupboards for demonstrating experiments; e) fume cupboards for the storage of chemicals; f) industrial and continuous production process enclosures; g) fume cupboards with openings on more than one side; h) fume cupboards with a direct make-up air supply. NOTE. Design criteria for laboratory fume cupboards are given in annex A.
