Where must exhaust ducts associated with clothes dryers terminate?

1. Inside the building

2. In the attic

3. Outside of buildings

4. In the basement

The correct answer is: Outside of buildings

The correct termination point for exhaust ducts associated with clothes dryers is outside of buildings. This requirement is crucial for several reasons. When dryer exhaust is expelled outdoors, it prevents the buildup of lint and moisture inside the home, which can lead to several issues, including mold growth, structural damage, and increased fire hazards. Additionally, terminating exhaust ducts outside allows the hot, moist air generated by the dryer to disperse safely into the environment, thus maintaining proper indoor air quality and comfort. Proper venting is an essential aspect of dryer installation that adheres to safety codes and building regulations to ensure efficient operation and reduce the risk of fire caused by lint accumulation within vents. The other options—terminating inside the building, in the attic, or in the basement—would all lead to dangerous conditions, as they could trap lint and moisture, creating fire hazards and promoting unhealthy indoor environments. Therefore, the only suitable option is to vent clothes dryer exhaust outside of buildings.
