The Regulatory Reform (Fire Safety) Order 2005 requires the Responsible Person (RP) of any non-domestic premises to carry out a fire risk assessment, including measures to reduce or eliminate the risk of fire, and identify persons at risk. Where there are 5 or more employees, a record must be kept of significant findings and a definition of a Responsible Person is contained in the above Order.
Where the RP does not have control of all parts of the building and it is shared with other persons, they should be informed of significant risks identified. The person who does have control (landlord, owner, or other employer etc.) has a responsibility to make sure the regulations are complied with, in the parts they control. This may require communication and cooperation between parties to ensure coordination of fire safety provisions, fire fighting measures, evacuation procedures etc.
