BS 9999:2017 Fire Safety in the Design, Management and Use of Buildings – Code of Practice has been updated by the British Standards Institution. The revised standard is intended to outline good practice in order to safeguard the lives of building occupants and firefighters alike.
BS 9999 provides recommendations and guidance on the provision of measures designed to control or otherwise mitigate the effects of fire, including information on business continuity and environmental matters.
The primary objective of the document is to ensure that a reasonable standard of life-safety can be achieved in the event of fire in a given building. The revised standard is applicable to the design of new buildings as well as material alterations, extensions and material change of use involving existing buildings.
BS 9999 has been revised to align the standard with current good practice and new technology and achieve consistency with other recently revised fire safety standards, namely BS 9990 and BS 9991.
The main changes in BS 9999 over the standard it replaces are as follows:
*an inclusion of a flowchart showing the sequential steps in the design process to assist users in the application of the standard
*a revised clause on fire safety management with references to PAS 7
*the inclusion of watermist fire suppression systems
*expansion of the guidance on voice alarms
*expansion of the fire growth rates table to provide more information
The revised standard also features updated recommendations for smoke and heat control, fire curtain barrier assemblies, mechanical ventilation and air conditioning systems, shopping complexes and ducting.
Users of this British Standard are likely to work within the design environment associated with a particular construction project governed by legislation, processes, constraints, programmes and deliverables that might vary dependent on premises type and location as well as client and regulatory requirements.
BS 9999 will be of key use to architects, building managers, fire safety engineers, fire risk assessors, building control personnel, Fire and Rescue Service personnel, the installers of fire and smoke alarms, sprinklers and smoke and heat control systems and inspectorates focused on certification and installation schemes.
BS 9999 isn’t applicable to the following types of buildings (which are covered in BS 9991): dwellings (single-family dwelling houses, self-contained flats or maisonettes) and residential accommodation blocks (eg for students or hospital staff) with individual bedrooms and the provision of kitchen/sanitary facilities constructed within a dedicated fire compartment.
