16、in catering establishments, burning 2nd or 3rd family gases.It is not applicable to LPG catering installations where appliances are sited temporarily in the open air, marquees or tents, or to LPG installations in mobile catering vehicles (see UKLPG CoP 24, Parts 3 and 4 22,23).NOTE 1 This standard a

17、lso applies to the installation of typical domestic cookers or leisure appliances such as barbecues when installed in commercial catering sites or establishments. It is not intended to apply to primarily domestic premises, e.g. those supplying a small number of clients on a “bed and breakfast” basis

18、. However, the general rules for hygiene and personal safety should be applied.NOTE 2 This standard covers a wide range of appliances, such as cookers, fish and chip frying ranges, fryers, ovens, caf boilers and urns, bain-marie units, tandoori ovens, kebab grills and barbecues.2 Normative reference

37、the installationThe following information shall be obtained and used in the process of designing the installation.a) The means of providing adequate dispersal of combustion and cooking fume products, and combustion air and ventilation for all of the appliances and cooking processes.NOTE Adequate fre

38、sh air is also required in kitchens to provide air for combustion to limit the effects of heat and humidity. Reference should be made to HSE Catering Information Sheets 10 24 and 23 25, HVCA publication DW/172 26 and BS 5925:1991+A1:1995, Annex B.b) For new and refurbished kitchens, the provision of

40、equirements of the catering equipment to be installed.d) Means of ensuring that an adequate supply of gas and electricity is available to agreed positions at the appropriate time in the project (see 5.1).BS 6173:20094 BSI 2009BRITISH STANDARDe) Method of ensuring that satisfactory transport access t

41、o the kitchen and preparation of the floor and of any special bases is completed before appliances are delivered to the site.NOTE Delivery of the appliances should be at a time as near to occupation of the premises as possible when the site is clean.f) The need for wheels, castors or rollers (see 8.

42、3.3).COMMENTARY ON CLAUSE 4To ensure a safe and satisfactory installation, collaboration is essential between those concerned with the design, selection, layout and installation of appliances and ventilation systems, both at the planning stage and during the execution of the work. It is essential th

43、at attention is given to catering and food hygiene and any need for appliance mobility for cleaning purposes. To ensure that good ventilation practices are applied, reference should be made to HVCA DW/172, Specification for Kitchen Ventilation Systems 26.Those involved in the collaboration process s

44、hould consider, amongst other things, the following.a) Food service:1) the number of meals required and peak time loads;2) the nature of meals required and types of food to be cooked;3) whether unprepared or convenience foods are to be used.b) Installation:1) the method of food service and food stor

45、age (hot and cold), and the time over which service is to be provided;2) peak energy requirements;3) the intended location of the appliance(s);4) hygiene, health and safety, for which advice may be sought from the local environmental officer;5) avoiding the siting of appliances adjacent to customer

46、services where hot surfaces might cause burns (see 6.1.3);6) the need to locate gas meters and other gas supply equipment in well-ventilated positions where they will not suffer corrosion or damage;7) the strength of floors and supports;8) the dimensions of appliances to enable compact groups to be

47、formed;9) the need for flush (easy clean) panels or services distribution units with accessible sides, fronts and backs;10) the need to avoid crevices between and behind appliances and pipework where spillage might lodge, but where crevices are unavoidable the necessity for appliances to be removabl

48、e for cleaning;NOTE Sealing methods and sealants should be vermin-proof, waterproof, flexible and food-safe grade.11) taking account of the requirements of BS 8313 and BS EN 12464-1 in the provision of other services.c) Ventilation:1) the provision of cleanable grease filters or sumps in extract duc

49、ts, especially on fryers and fish and chip ranges.These filters or sumps will normally need regular attention.BRITISH STANDARD BSI 2009 5BS 6173:2009Some grease vapour will pass through the filters, so duct interiors need to be easily accessible with doors and panels.NOTE See also BSRIA Report 78610 Specification for Ventilation Hygiene 27 and HVCA DW/143 28, and TR/19 29.2) taking into account: cooking load; amount of cooking equipment used; layout and shape of kitchen;
