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 forage (herbage feed for stock) stores. It does not cover forage silo towers.

General

  • Consideration must be given to all the appropriate legislation e.g. BS5502:11.
  • Site selection should consider flooding potential, proximity to stock housing, ease of access for handling equipment, ground bearing capacity and potential for future expansion.
  • Silage stores must be at least 10m from any controlled water. See Defra Water Code.
  • Stores should be adequately sized.
  • Buildings, structure, walls and floors should be capable of handling the maximum potential loadings.
  • Windows and doors should be bird, pest and vermin protected.
  • Details and specifications for construction materials are given in the full Standard.
  • COSHH Regulations must be complied with and assessments carried out.

Services

  • Toxic gases can build up inside stores and so good ventilation is necessary.
  • All below-ground stores and effluent tanks should be protected against accidental entry especially by children.
  • Protection against infestations will be necessary in accordance with BS5502:30.
  • Fire precautions will be required in accordance with BS5502:23.
