11、word This Part of this BS5502 has been prepared under the direction of the Farm and Horticultural Buildings Standards Policy Committee and comprises a revision of BS5502-1.6 and BS5502-3.6., which are withdrawn. While BS5502 is being revised and added to, the opportunity is being taken to restructur
12、e the standard into the following broad subject areas: Part0: Introduction and consolidated index; Parts10 to19: Reference information and legislation; Parts20 to39: General design; Parts40 to59: Livestock buildings; Parts60 to79: Crop buildings; Parts80 to99: Ancillary buildings. More specifically,
13、 the ancillary building series will comprise: Part80: Code of practice for design and construction of workshops, maintenance and inspection facilities; Part81: Code of practice for design and construction of chemical stores; Part82: Code of practice for design of amenity buildings. A more detailed d
14、escription of the new structure of BS5502 is given in Part0. The object of introducing the new structure is to allow subject areas to be broadly characterized, and related subject matter, whether in the form of recommendations, guidance or supporting data, to be rationalized and brought together. It
15、 will also allow sufficient flexibility to allow the standard to be expanded and developed in a logical way in the future. It has been assumed in the drafting of this British Standard that the execution of its provisions is entrusted to appropriately qualified and experienced people, for whose guida
16、nce it has been prepared. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of page

18、-80:1990 BSI 03-1999 1 1 Scope This Part of BS5502 gives recommendations on the design and construction of buildings for use in agriculture as workshops and implement sheds and for working areas and facilities used for access for the purposes of repair, maintenance and inspection. NOTEThe titles of
19、the publications referred to in this standard are listed on the inside back cover. 2 Definitions For the purposes of this standard, the definitions given in BS6100 apply. NOTEWork has commenced on a further Part of BS5502 (Part10) which will be a glossary of terms for buildings and structures for ag
20、riculture. 3 Workshops and implement sheds 3.1 Siting Workshops and implement sheds should, where possible, be sited away from the public highway and clear of other buildings, trees, etc. to minimize the risk of fire spread. Hard standings and a paved access road with adequate vehicle turning space
21、should be provided. 3.2 Design and construction 3.2.1 General Workshops required for the repair and maintenance of vehicles, implements and machinery used for agricultural purposes should be designed and constructed in accordance with the general design series of this British Standard (see BS5502-20
22、 to BS5502-25 inclusive). NOTEAttention is drawn to the provisions of the building regulations (see also BS5502-11 1) ). 3.2.2 Dimensions and space 3.2.2.1 Dimensions Workshops and implement sheds should be designed to give good working access for vehicles and equipment and for the personnel servici
23、ng them. Doorway openings should be wide enough and high enough to allow easy access to the largest implements. A guide to the overall heights of some farm vehicles and equipment is given inTable 1. The clear height inside the building should also be sufficient to allow the use of lifting-gear, ramp
24、s and other equipment for servicing the largest vehicle and equipment anticipated. Table 1 Maximum overall heights of farm vehicles and equipment 3.2.2.2 Layout of working areas Consideration should be given to the area required for the safety of the operator at work, bearing in mind the following f
25、actors: a) the operators physical dimensions (seeAppendix A); b) the placing of plant and machinery so that the operator can watch it operating; c) the accessibility of controls and equipment for safe manipulation; d) the avoidance of hazards which may be caused by the wearing of protective clothing
26、 or by handling equipment. 3.2.3 Floors Floors should be designed and constructed to withstand the maximum loading from vehicles and equipment and to avoid slippery, dangerous or uneven surfaces. Surfaces should also be hard wearing and finished to facilitate easy cleaning and removal of accumulatio
27、ns of dirt and grease and to minimize dusting. 3.2.4 Walls and roof Foundations and walls should be designed to support loads from overhead lifting beams and gantries when needed. Consideration should be given to thermal insulation of the walls and roof to improve operator comfort and minimize the f
28、reezing of equipment. 1) In preparation.

30、pboard space for operatives clothing. 3.3 Environment 3.3.1 Ventilation Precautions should be taken in the design of service buildings to ensure appropriate ventilation to prevent the possible accumulation of potentially toxic or explosive atmospheres. NOTEFor humans, the time-weighted average wet-b
31、ulb globe temperature should not exceed30 C without precautions being taken. Discomfort will be experienced at an average wet-bulb globe temperature of25 C, or20 C where considerable physical work is being undertaken. For comfort, airflow should be restricted to0.15m/s to0.3m/s Airflows below0.1m/s
32、are considered “airless”, and above0.5m/s “draughty”. 3.3.2 Heating Heating should be provided in insulated buildings which are used throughout the year. NOTESee ADAS Leaflet758 “The farm workshop”, published by MAFF (HMSO). It may be necessary to provide infra-red heat in certain uninsulated buildi
33、ngs. Quartz linear heaters should be used for this purpose. 3.3.3 Lighting The levels of illumination both from natural and artificial sources should provide sufficient light for the efficient and safe execution of work being done by an operative. Illumination levels should always give sufficient li
34、ght to enable an operative to work in any part of the building. For recommendations for the level of illumination of workplaces seeTable 2 and BS5502-20. The frequency of the light source near rotating or reciprocating machinery should be such that there is no stroboscopic effect. Table 2 Minimum le
35、vels of lighting for workshops and maintenance areas 3.3.4 Hazardous atmospheres and noise The recommendations given in BS5502-32 to BS5502-35 2)should be followed. 3.4 Services 3.4.1 Electricity Electrical installations should be in accordance with the recommendations of BS5502-25. Equipment and in
36、stallations should be resistant to impact. Socket outlets should be provided by work benches for portable hand tools and machinery. Provision should also be made for inspection lamps. Fixed machine tools should be permanently connected. Socket outlets for inspection lamps and portable equipment shou
37、ld be adequate in number and sited so that the lengths of flexible cable connection are kept to a practical minimum. Any battery-charging facilities should be provided in an adequately ventilated area and away from naked flames. It is recommended that socket outlets used for portable tools and equip
38、ment should include residual current circuit breakers (RCCBs) to protect operators from shock, unless a110V supply is used with earthed centre tap and appropriately rated appliances. Where110V supplies are available at socket outlets, it is essential that the plugs and sockets comply with BS4343 to
39、prevent110V plugs being inserted into240V socket outlets. 3.4.2 Water The water services should be designed in accordance with BS5502-25 and consideration should be given to the need for high pressure water and steam supplies. 3.4.3 Compressed air Compressed air supplies, when required should be des
40、igned in accordance with BS5502-25.

41、he drainage system should be designed in accordance with BS5502-25, to prevent the accumulation of fuels or explosive gases in the drains and to be accessible for clearing at suitable points. Petrol-intercepting traps should be installed when required. 3.5 Fire protection and safety NOTEAttention is
42、 drawn to the requirements of the statutory authorities regarding fire and safety. Welding bays and fixed forges should be suitably screened. Liquid fuel storage should be designed in accordance with the recommendations given in BS5502-25. Workshops and maintenance areas should be designed to allow
43、for the fact that they are high fire risk buildings. Fire protection should be in accordance with the recommendations of BS5502-23. Suitable fire extinguishers, including dry powder and foam types, and fire blankets should be provided in both workshops and implement sheds and kept in prominent and a
44、ccessible positions. 3.6 Security Doors of workshops should be provided with locks and additional security should be provided for stores. 3.7 Inspection pits Where inspection pits are provided they should comply with the safety regulations, be waterproof, have steps at both ends and have safety barr
45、iers or adequate covers capable of withstanding maximum vehicle and equipment loadings (see also BS5502-50). 3.8 Fixtures and fittings Fixtures and fittings should be so constructed as to be rigid and secure and without sharp projections. 4 Working platforms 4.1 General 4.1.1 Working platforms (seeF
46、igure 1) giving access to plant and machinery should be provided wherever work has to be carried out, e.g.hoisting a conveyor, or handling a chute, etc., and be designed in accordance with BS6180 or BS5395-3. Platforms should be at the proper level, of adequate strength, securely fixed in position a
47、nd surrounded by a guard rail and toe boards, leaving access only where the platform is connected to a ladder or catwalk. Figure 1 Example of a typical working platformBS5502-80:1990 4 BSI 03-1999 4.1.2 The minimum dimensions of any platform should permit two operatives to work side by side, e.g.a m
48、inimum length of2.0m and a minimum width of1.0m. Toe boards should be not less than150mm high. 4.2 Guard rail A guard rail (or wall) should be not less than910mm and not more than 1050mm above the height of any roof ladder, catwalk or platform and have an intermediate rail midway between the guard r
49、ail and platform. 4.3 Location of guard rails Guard rails should be supplied when the height at which an operative has to work exceeds1.5m above ground level. 5 Stairways, ladders and catwalks 5.1 Stairways Stairways should be properly constructed and sufficiently strong to support a mass of180kg (the combined mass of an operative carrying the maximum permitted load) and not less than600mm wide. Recommendations for dimensions, headroom, angle of slope, etc., are given inAppendix B. 5.2 Roof ladders and catwalks Roof ladders and catwal
