British Standard Summaries

BS5502: Part 72: 1992
Building and Structures for Agriculture.
Design and Construction of Controlled Environment  Stores for Vegetables, Fruit & Flowers.


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 stores used for storing vegetables, fruit and  flowers under controlled temperature, humidity and atmospheric conditions.

General

  • Consideration should be given to the siting of the building. Specific issues are access (especially for large vehicles), the location of services and potential noise nuisance to neighbours.
  • Design of controlled environment stores depends upon:
    • Produce type
    • Storage duration
    • Enterprise scale
    • Handling method
    • Any alternative uses ther building may have.
  • 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.
  • Stores should be sealed against the passage of gases.
  • Windows and doors should be bird, pest and vermin protected.
  • Floors should be level with an even surface.
  • Store interiors should be designed to facilitate easy cleaning.
  • Natural light should be excluded.
  • Stores should be insulated. The full Standard provides details.
  • The full Standard provides design and construction details for sealing environment controlled stores.

Services

  • Crop storage life will be dependant upon the environmental conditions.
  • The lower the temperature the slower the rate of degradation but too low a temperature will damage the produce by destroying the plant cell structure.
  • The full Standard provides tables of optimum storage temperatures and relative humidities for a range of produce.
  • Storage life is determined by rate of respiration. This can be temperature controlled.
  • Electicity services will be required.
  • Good lighting 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.

A British Standard nor this summary does not, necessarily, include all the necessary information for correct implementation of the Standard to any specific application. This is purely the responsibility of the user. Standards are updated by either amendment or revision. Users should ensure that they are using the latest version.
