BS 9999:2017 Code of Practice for Fire Safety in the Design Management and use of Buildings details the four principle methods of protection as follows:

Method 1 - Protection using Fire Dampers (thermally actuated)
Method 2 - Protection using Fire Resisting Enclosures
Method 3 - Protection using Fire Resisting Ductwork
Method 4 - Protection using Fire and Smoke Dampers (automatically actuated via smoke detectors)

Good practice dictates that fire dampers should not be installed in the following systems and therefore Fire Resisting Ductwork is used.

  • Smoke extraction systems
  • Dual ventilation/smoke extraction systems
  • Car park extraction systems
  • Kitchen extraction systems
  • Pressurisation systems

*Motorised fire/smoke dampers may be used in conjunction with fire resisting ductwork but not in kitchen extract systems.
Fire resisting ductwork may prove to be a cost effective alternative to fire dampers in general ductwork systems (particularly over the lifetime of a building).

No capital or installation cost of fire/smoke dampers and associated access doors.
No reliance on mechanical fire dampers which may fail in time.
No regular testing regime.
No electrical wiring and control system associated with smoke dampers.
