The vacuum exhaust must discharge a minimum of how many feet from any door, window, or air intake?

The correct answer is that the vacuum exhaust must discharge a minimum of 25 feet from any door, window, or air intake to ensure proper ventilation and to prevent any potential contamination or disruption in air quality. This distance is regulated to minimize the risk of exhaust fumes or contaminants re-entering the building through openings where fresh air is drawn in or where people may enter and exit. By maintaining this distance, the design adheres to safety standards aimed at protecting the health and safety of the occupants and ensuring that the air quality remains stable. This guideline reflects an understanding of airflow dynamics and the importance of maintaining a safe environment in medical and healthcare settings where gases and exhaust must be managed carefully.
