Which capacity defines a Bulk Oxygen System?

• A. 3,000 ft3
• B. 20,000 ft3
• C. 28,000 ft3
• D. 10,000 ft3

Answer: (B)

This item tests the capacity threshold that separates bulk oxygen storage from smaller cylinder systems. A bulk oxygen system is defined by having a storage capacity of 20,000 cubic feet of gaseous oxygen at standard conditions. That minimum size is used to indicate on-site bulk storage capable of supplying a facility through a central distribution system rather than relying on many small cylinders. So, 20,000 ft3 is the defining threshold: it marks the point at which storage shifts from small, cylinder-based supply to bulk, piped or large-tank delivery. Values well below that, like 3,000 or 10,000 ft3, are not considered bulk. A larger amount, such as 28,000 ft3, would also be bulk, but the standard criterion used to define the category is 20,000 ft3.
