I would think it's more to prevent fire from moving easily between floors, and perhaps for HVAC efficiency reasons.

- fsckboy 6y agothe trash chute doors on each floor are spring loaded, close automatically, and have a gasket seal, and they are inspected and kept up to spec. they are also in a closet behind an ordinary "residential" fire proof door like the apartment doors. Sealing in/out odor also stops airflow, happy coincidence. there are other ventilation systems that move air all over the building (they bring it in from outside, filter it, condition it, and pump it into hallways (elevator lobbies) up and down the building; it travels under the apartment front doors, and it is sucked out the bathroom vents; it is called "make-up air") These other fans and vent systems also shut down and seal and seal if heat/smoke/fire is detected. buildings are intricately balanced mechanical engineering systems where all the parts are intertwined
