- Fire Smoke Damper for Shaft Enclosure - HVAC R engineering
If the roof assembly is not rated, then you need a fire damper at the OA duct penetration at the bottom of the rated shaft A SFD could be applied but a FD with the correct rating should meet your requirements
- Firestopping Vertical Horizontal Penetrations
The spread of fire can be restricted by dividing a building into separate compartments with fire-resistive walls and floors—increasing the availability of escape routes for occupants One globally applied principle for fire safety:
- Enclosing Shafts to Reduce Fire Spread in Construction
Shafts, such as elevator shafts and stairwells, can provide a path for fire and smoke to travel vertically between floors Enclosing these shafts helps contain the fire and limit its spread, providing more time for evacuation and firefighting efforts
- Cheat Sheet Table: Where are Fire or Smoke Dampers Required?
