When providing a barrier to separate oxygen cylinders from combustibles, the barrier height must be at least

• A. 3 feet
• B. 4 feet
• C. 5 feet
• D. 6 feet

Answer: (C)

The key idea is that a barrier between oxygen cylinders and combustibles creates a physical safety buffer that reduces the chance of ignition or heat transfer from one area to the other. By making this barrier a sufficient height, you ensure there’s a clear, climb-resistant separation that helps keep combustibles away from potential ignition sources and slows flame spread if a leak or fire occurs. The standard requires the barrier to be tall enough to serve as an effective divider, and the minimum height specified is five feet. A shorter barrier wouldn’t provide the needed separation, while a taller one would still satisfy the requirement but isn’t the minimum.
