What minimum distance is prescribed for medical air intakes from exhausts to avoid contamination?

The minimum distance prescribed for medical air intakes from exhausts to avoid contamination is 25 feet. This requirement is established to ensure that the air quality within medical facilities remains uncontaminated by exhaust emissions, which can carry harmful pollutants, odors, and particulate matter. By maintaining a significant distance between air intakes and exhaust sources, the standard aims to protect the health and safety of patients and healthcare workers. This precautionary measure is crucial in environments where clean, uncontaminated air is essential for medical operations and procedures, safeguarding against potential degradation in air quality that could arise from nearby exhaust systems.
