   Smoke dampers can be activated by the fire alarm system, usually initiated by smoke detectors, or interlocked with a fire suppression system. Smoke dampers close by an electric or pneumatic actuator, or a spring actuator, and can be either manually reset or driven open on a reset signal to the electric or pneumatic actuator.

   Stairwells, shafts, elevators, and the like, tend to contribute to the stack effect, while interior partitions, floors, and fire separations can mitigate it. Especially in case of fire, the stack effect needs to be controlled to prevent the spread of smoke and fire, and to maintain tenable conditions for occupants and firefighters. [2]

5. Chimney starter - Wikipedia

   en.wikipedia.org/wiki/Chimney_starter

   Chimney starters essentially work by increasing the draft, supplying more oxygen to the coals. Taller starters are more effective than shorter ones. In empirical studies of lighting cones for Haitian charcoal stoves (which are placed over a grate rather than having an integrated grate), the ignition time and charcoal consumption were halved compared to lighting on a shallow bed grate, and ...

6. Fire damper - Wikipedia

   en.wikipedia.org/wiki/Fire_damper

   Fire/smoke dampers are similar to fire dampers in fire resistance rating, and also prevent the spread of smoke inside the ducts. When a rise in temperature occurs, the fire damper closes, usually activated by a thermal element which melts at temperatures higher than ambient but low enough to indicate the presence of a fire, allowing springs to ...
