CORRIDOR SMOKE EXTRACTION SYSTEM
Corridors are provided with a mechanical smoke purge system. The intent of a smoke purge system is for the clearance/removal of smoke during evacuation and firefighting operations. Make up air shall be adequately supplemented based on the total smoke extract capacity.
STATIC SMOKE EXTRACTION SYSTEM
A smoke extraction system utilizing smoke reservoirs; localized ducting; and permanent openings and / or automatic opening of windows, panels or external louvres actuated by smoke detectors; to remove, on the principles of natural ventilation.
DYNAMIC SMOKE EXTRACTION SYSTEM
A mechanical ventilating system capable of removing smoke and products of combustion from a designated fire compartment, and also supplying fresh air in such a manner as to maintain a specified smoke free zone below the smoke layer.
SMOKE CONTAINMENT & MANAGEMENT
- Smoke extract system for atriums, large warehouses & factories are to be carefully designed.
- Fixed/Automatic smoke curtains will be required to create the necessary zoning in coordination with other fire rated services such as Fire Sprinkler/Fire Alarm.
- Automatic Fire Curtains/Fire Shutters are required to be provided for larger compartments to segregate from the remaining part of the building
- Smoke Extraction can be naturally through Smoke Vents or mechanically by Fire Rated Fans.
- Make up air shall be supplied adequately below the smoke layer at a minimum velocity by means of mechanical fans or naturally by means of louvres or entrance doors interfaced to fire alarm control panel.
