High-pressure gas cylinders serve which purpose in medical gas systems?

• A. Small installations or as a reserve supply for larger installations
• B. Main supply for all facilities
• C. Only for testing
• D. Only for emergency exhaust

Answer: (A)

High-pressure cylinders provide a portable, ready-to-use source of gas that supports small installations or serves as a backup for larger systems. They’re ideal when a facility is being started up, expanded, or during maintenance, because they can be brought online quickly and without relying on the central pipeline or bulk supply. In a larger setup, the main supply comes from the piped or bulk system, while cylinders act as a reserve to ensure continuous availability of gas. They aren’t meant to be the primary supply for an entire facility, which is why this option best fits their typical role.
