What is the minimum separation distance between oxygen cylinders and fuel-gas cylinders if no barrier is used?

• A. 10
• B. 20
• C. 30
• D. 40

Answer: (B)

When oxygen cylinders are stored with fuel-gas cylinders and there isn’t a barrier between them, the distance between these two gas groups becomes a critical safety measure. Oxygen supports combustion, and fuel gas provides the fuel, so a leak, heat, or a spark could cause a fire to spread more quickly if the cylinders are too close. Keeping them at least twenty feet apart minimizes the chance that heat, ignition sources, or a developing fire in one area will reach the other group. Distances smaller than twenty feet would not provide enough clearance to prevent rapid fire spread, while larger distances are not required for this scenario.
