Dry Risers in the UK must be designed and installed in accordance with BS 9990:2015.  BS 9990 outlines recommendations for non-automatic fire-fighting systems in buildings. It covers good practice in matters affecting the design, installation, testing and maintenance of wet and dry fire-fighting mains and includes recommendations for provision and siting.

BS 9990 covers information on:

  • Installation Specification
  • Service and Maintenance
  • Testing and commissioning

BS 9990:2015 was released January 2015 and is available from the BSI shop. It Supersedes BS 9990:2006.

When are dry risers required?
