Describes how historic and listed buildings can be best protected from the effects of fire. Explains that heritage buildings are often particularly vulnerable to fire because of the fragility of the structure and the fact that they are often open to the public. There are many considerations associated with fire management planning for these buildings but the most important include the use of legislation as a project management tool and the elimination of false and unwanted alarms without dilution of system performance. Advises that an important first step is the identification and understanding of the fire hazards and either eliminating them or managing the risk; all employers have a responsibility to carry out a risk assessment under the Fire Precautions (Workplace) Regulations 1997. Mentions two pieces of legislation to be aware of when considering a system, the BS 5839-1: 2002 and a newly introduced scheme to promote third party accreditation of the main aspects of installation.
