General Ventilation Systems
Depending on the local authority codes of practice it may be necessary to use fire resisting ductwork (possibly in conjunction with automatic fire/smoke dampers) in areas where there is a high risk of fire or where the ducts pass over or across protected escape routes.
Situations where fire resisting ductwork might be used in lieu of standard ductwork / fire dampers include:
- Enclosed / Underground Car Park ventilation
- Basement ventilation
- Rooms containing flammable materials or materials with a low ignition point
- Escape routes – used in conjunction with automatic fire/smoke dampers
- Lift Shaft ventilation
- Passive Air Transfer Ducts
