Which device is specifically associated with the regulator in the context of this equipment set at 145-165 psig?

• A. Vibralert
• B. Quick disconnect
• C. Facepiece
• D. Pressure gauge

Answer: (A)

The regulator assembly often includes a built‑in low‑air alert that activates when the regulator’s output pressure drops into a critical range. This tactile notification, the Vibralert, is designed to vibrate to warn the wearer that the air supply is getting low and action is needed. At the regulator’s operating range around 145–165 psi, the Vibralert is triggered so you can recognize the need to conserve air or exit safely. The quick disconnect is simply the coupling to the cylinder, the facepiece is the mask you breathe through, and the pressure gauge shows remaining pressure but does not provide the active warning signal—that role belongs to the Vibralert attached to the regulator.
