Building and Structures for Agriculture.
Design and Construction of Chitting Houses.


The text herein is not a a full reproduction of the British Standard. It is summary based upon interpretation of the original text and not intended as a replacement for the full text. It should be used for general guidance only.

BS5502 is sub-divided into a number of individual standards. These can be broadly broken down as follows:

  • Part 0: Introduction
  • Parts 10 - 19: Reference information
  • Parts 20 - 39: General designs
  • Parts 40 - 59: Livestock buildings
  • Parts 60 - 79: Crop buildings
  • Parts 80 - 99: Ancillary buildings

This part of BS5502 gives recommendations for the design and construction of buildings used for the controlled sprouting of seed potatoes prior to planting - chitting. It covers naturally and artifically lit stores including those that are refrigerated.

General

  • Consideration should be given to the siting of the building. In particular access, proximity of land to be planted and  the location of services need consideration.
  • Stores for chitting potatoes can be lit naturally, by artifical lighting or unlit. Choice of system will be determined by the size of the enterprise, consideration of other enterprises carried out in the same areas and capital/running costs.
  • Consideration must be given to all the appropriate legislation e.g. BS5502:11.
  • Buildings, structure, walls and floors should be capable of handling the maximum potential loadings.
  • Materials and treatments should not impart odour or taint.
  • Windows and doors should be bird, pest and vermin protected.
  • Size and layout will be determined by the enterprise nature and scale.
  • The building should be protected against weather.
  • Floors should be level with an even surface.

Services

  • Environmental conditions within the store will affect the chitting. Potatoes produce heat as a result of respiration. This heat may need to be removed or recirculated to maintain the required environmental conditions.
  • Condensation and free moisture should be avoided otherwise crop may rot.
  • Electicity services will be required.
  • Ventilation will be required.
  • Water supplies and drainage facilities will be required.
  • Protection against infestations will be necessary in accordance with BS5502:30.
  • Fire precautions will be required in accordance with BS5502:23.
