Which system shall not be permitted to be located in an outdoor enclosure?

• A. Bulk cryogenic liquid systems
• B. Manifolds for gas cylinders
• C. Manifolds for cryogenic liquid containers
• D. Medical air compressor sources

Answer: (D)

Placing medical gas equipment requires considering safety, gas quality, and maintenance needs. Medical air compressor sources should not be located in an outdoor enclosure because they generate heat, require reliable climate control, and must be protected from weather, dust, and moisture. Oil-lubricated or even some oil-free compressors can release oil aerosols or condensate into the air stream if environmental conditions are poor or if the system isn’t perfectly protected and filtered. Outdoor exposure also makes routine service and emergency maintenance harder, and weather or temperature swings can affect performance and reliability of the compressor and its control systems. All of this risks compromising the cleanliness and dryness of medical air, which must meet strict standards for patient care. In contrast, systems like bulk cryogenic liquids and their manifolds are designed to vent boil-off safely and are typically located outdoors or in ventilated spaces to manage those gases. Cylinder manifolds and cryogenic liquid container manifolds are also commonly situated in areas that can be ventilated and accessed for safe operation. So those configurations fit outdoor or semi-outdoor locations more readily, while indoor placement is essential for medical air compressor sources.
