Which description fits a bulk oxygen system?

A bulk oxygen system is characterized by its large capacity to store oxygen, typically defined as holding more than 20,000 cubic feet of oxygen. This system is designed to supply an extensive volume of oxygen, suitable for medical facilities or large-scale applications where consistent and high demand is necessary, such as hospitals. These systems are often integrated into a network of pipes that deliver oxygen directly to various points of use throughout a medical facility.

The other descriptions do not accurately capture the essence of a bulk oxygen system. For instance, maintaining under 20,000 cubic feet refers to smaller systems, which are not classified as bulk. A small gas tank provides limited quantities for personal or grouped use, whereas a bulk system encompasses a comprehensive infrastructure supporting extensive medical needs, which is not reflective of personal or small-scale storage solutions.
