What type of air pressure is required in line and trash chute rooms?

Maintaining negative air pressure in line and trash chute rooms is essential for effective airflow management and to prevent contamination. This setup ensures that any airborne pathogens, odors, or contaminants generated in these areas are drawn back into the chute and away from other occupied areas of the building. By having negative pressure, air flows inward towards the chute room, effectively minimizing the risk of air leaking out into surrounding spaces.

In environments such as hospitals or commercial buildings where sanitation is critical, negative pressure helps contain any potential pollutants and contributes to overall air quality control. This practice creates a safer environment for both staff and occupants by preventing the spread of odors and harmful airborne particles. In contrast, positive pressure would risk pushing contaminants out into adjacent spaces, while equal pressure would not provide a clear directional flow to manage pollutants effectively. Therefore, the requirement for negative air pressure is crucial in line and trash chute rooms to uphold health and safety standards.
