Final Decision RIS This final Regulation Impact Statement (RIS) assesses the costs and benefits of requiring fire hose reels in (Class 5) office buildings. The Final RIS has been updated to reflect feedback received during the consultation period from interested parties. In February 2017 the Board agreed to replace the requirement for fire hose reels with one to install fire extinguishers to address Class A fire risks in recognition of the lower risk and benefits to life safety outlined in the ARUP fire risk assessment.
