Abstract
A protective cap assembly for a pressurized valve adapted to detect a leak therethrough. In accordance with various embodiments, the cap assembly includes a body adapted for placement in fluid communication with the valve, and a sensory indicator supported by the cap assembly body to provide human sensory indication of pressurized fluid leaking from the valve in its closed position. In various embodiments, the sensory indicator can be a whistle that makes an audible sound, a light emitting device that emits a visible light, or both. In further embodiments, the cap assembly body can be coupled to the vent conduit via a tether, and ejected responsive to exhausted pressurized fluid when the valve transitions to the open position. The displaced cap assembly body serves as a visual indication that the valve has opened.
