The burst disk releases pressure from an over-pressurized cylinder by opening a spring-loaded release valve. Is this statement true or false?

The statement is false because a burst disk functions differently than described. A burst disk is a safety device designed to rupture at a specific pressure, allowing excess pressure to escape from a cylinder safely. It does not operate by opening a spring-loaded release valve; instead, it is a one-time-use component that provides a fail-safe mechanism by preventing over-pressurization.

Spring-loaded valves, on the other hand, can be adjusted and reused, as they open and close based on pressure conditions. While both devices are meant to relieve pressure, their mechanisms and operational principles are distinct.

Understanding this distinction is crucial for dive safety, as recognizing the function of safety devices ensures proper handling and maintenance of high-pressure systems in diving equipment.
