12、Foreword This Part of this BS 5502 has been prepared under the direction of the Farm and Horticultural Buildings Standards Policy Committee and comprises a revision of BS 5502-1.6 and BS 5502-3.6., which are withdrawn. While BS 5502 is being revised and added to, the opportunity is being taken to re
13、structure the standard into the following broad subject areas: Part 0: Introduction and consolidated index; Parts 10 to 19: Reference information and legislation; Parts 20 to 39: General design; Parts 40 to 59: Livestock buildings; Parts 60 to 79: Crop buildings; Parts 80 to 99: Ancillary buildings.
14、 More specifically, the ancillary building series will comprise: Part 80: Code of practice for design and construction of workshops, maintenance and inspection facilities; Part 81: Code of practice for design and construction of chemical stores; Part 82: Code of practice for design of amenity buildi
15、ngs. A more detailed description of the new structure of BS 5502 is given in Part 0. 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
16、and brought together. It 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
17、 people, for whose guidance 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 obli
18、gations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 10, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amendment table on
19、 the inside front cover. Licensed Copy: sheffieldun sheffieldun, na, Mon Dec 04 14:41:09 GMT+00:00 2006, Uncontrolled Copy, (c) BSI BS 5502-80:1990 BSI 03-19991 1 Scope This Part of BS 5502 gives recommendations on the design and construction of buildings for use in agriculture as workshops and impl
20、ement sheds and for working areas and facilities used for access for the purposes of repair, maintenance and inspection. NOTEThe titles of 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 BS 6
21、100 apply. NOTEWork has commenced on a further Part of BS 5502 (Part 10) which will be a glossary of terms for buildings and structures for agriculture. 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
22、 other buildings, trees, etc. to minimize the risk of fire spread. Hard standings and a paved access road with adequate vehicle turning space 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
23、 agricultural purposes should be designed and constructed in accordance with the general design series of this British Standard (see BS 5502-20 to BS 5502-25 inclusive). NOTEAttention is drawn to the provisions of the building regulations (see also BS 5502-111). 3.2.2 Dimensions and space 3.2.2.1 Di
24、mensions Workshops and implement sheds should be designed to give good working access for vehicles and equipment and for the personnel servicing 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 ve
25、hicles and equipment is given in Table 1. The clear height inside the building should also be sufficient to allow the use of lifting-gear, ramps 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 Lay
26、out of working areas Consideration should be given to the area required for the safety of the operator at work, bearing in mind the following factors: a) the operators physical dimensions (see Appendix A); b) the placing of plant and machinery so that the operator can watch it operating; c) the acce
27、ssibility of controls and equipment for safe manipulation; d) the avoidance of hazards which may be caused by the wearing of protective clothing 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
28、slippery, dangerous or uneven surfaces. Surfaces should also be hard wearing and finished to facilitate easy cleaning and removal of accumulations 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 an
29、d gantries when needed. Consideration should be given to thermal insulation of the walls and roof to improve operator comfort and minimize the freezing of equipment. 1) In preparation.

31、99 3.2.5 Welfare facilities The following facilities should be readily available (also see BS 5502-25): a) toilet facilities; b) wash basins with hot and cold water and dispensers for degreasing fluid; c) a first aid cabinet; d) adequate cupboard space for operatives clothing. 3.3 Environment 3.3.1
32、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-bulb globe temperature should not exceed 30 C without precaut
33、ions being taken. Discomfort will be experienced at an average wet-bulb globe temperature of 25 C, or 20 C where considerable physical work is being undertaken. For comfort, airflow should be restricted to 0.15 m/s to 0.3 m/s Airflows below 0.1 m/s are considered “airless”, and above 0.5 m/s “draugh
34、ty”. 3.3.2 Heating Heating should be provided in insulated buildings which are used throughout the year. NOTESee ADAS Leaflet 758 “The farm workshop”, published by MAFF (HMSO). It may be necessary to provide infra-red heat in certain uninsulated buildings. Quartz linear heaters should be used for th
35、is 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 light to enable an operative to work in any part o
36、f the building. For recommendations for the level of illumination of workplaces see Table 2 and BS 5502-20. The frequency of the light source near rotating or reciprocating machinery should be such that there is no stroboscopic effect. Table 2 Minimum levels of lighting for workshops and maintenance
37、 areas 3.3.4 Hazardous atmospheres and noise The recommendations given in BS 5502-32 to BS 5502-352) should be followed. 3.4 Services 3.4.1 Electricity Electrical installations should be in accordance with the recommendations of BS 5502-25. Equipment and installations should be resistant to impact.
38、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 should be adequate in number and sited so that
39、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 equipment should include residual current circui
40、t breakers (RCCBs) to protect operators from shock, unless a 110 V supply is used with earthed centre tap and appropriately rated appliances. Where 110 V supplies are available at socket outlets, it is essential that the plugs and sockets comply with BS 4343 to prevent 110 V plugs being inserted int
41、o 240 V socket outlets. 3.4.2 Water The water services should be designed in accordance with BS 5502-25 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 designed in accordance with BS 5502-

Petrol-intercepting traps should b
44、e installed when required. 3.5 Fire protection and safety NOTEAttention is 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
45、in BS 5502-25. Workshops and maintenance areas should be designed to allow for the fact that they are high fire risk buildings. Fire protection should be in accordance with the recommendations of BS 5502-23. Suitable fire extinguishers, including dry powder and foam types, and fire blankets should b
46、e provided in both workshops and implement sheds and kept in prominent and accessible 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 saf
47、ety regulations, be waterproof, have steps at both ends and have safety barriers or adequate covers capable of withstanding maximum vehicle and equipment loadings (see also BS 5502-50). 3.8 Fixtures and fittings Fixtures and fittings should be so constructed as to be rigid and secure and without sha
48、rp projections. 4 Working platforms 4.1 General 4.1.1 Working platforms (see Figure 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 BS 6180 or BS 5395-3. Platforms
49、should be at the proper level, of adequate strength, securely fixed in position and surrounded by a guard rail and toe boards, leaving access only where the platform is connected to a ladder or catwalk.
