Which term describes three or more large, interconnected air cylinders, from which smaller SCBA cylinders are recharged; the larger cylinders typically have a capacity of 300 cubic feet (8,490 L)?

A cascade system is a bank of three or more large, interconnected air cylinders used to recharge smaller SCBA cylinders. Air is stored at high pressure in these large cylinders, and through regulators and manifolds it is transferred to fill the SCBA bottles quickly and safely. The larger cylinders often have a capacity around 300 cubic feet, providing enough stored air to fill multiple SCBAs before needing a top-off. The interconnected setup lets you continue filling even as individual cylinders deplete, ensuring rapid turnaround at the station or on scene.

This term is distinct from other options: a certification test is about validating skills, the angle of approach relates to vehicle positioning, and automatic electrical load management concerns power distribution, not SCBA air storage and filling.
