- An inclusion of a flowchart showing the sequential steps in the design process, to assist users in the application of the standard
- Revised clause on fire safety management with references to PAS 7
- Inclusion of watermist fire suppression systems
- Expansion of the guidance on voice alarms
- Expansion of 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.
BS 9999 is not 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 fire compartment.
