The minimum distance requirement at #1 is

• A. 15 ft
• B. 20 ft
• C. 25 ft
• D. 10 ft

Answer: (D)

In medical gas safety, keeping a clear separation between oxygen systems and potential ignition sources is essential because oxygen-rich environments ignite more easily. The minimum distance of 10 feet provides a safety buffer that reduces the chance that a leak or spark could ignite flammable material and also gives space for personnel to access valves, regulators, and shutoffs if needed. It also helps ensure adequate ventilation around the outlet so any incidental release dilutes rather than concentrates. Larger distances exist in some situations, but 10 feet is the minimal requirement that balances safety with practicality.
