The bypass valve on an SCBA is used in which scenario?

Explanation:
The bypass valve is a safety feature that lets air flow directly from the cylinder to the facepiece, bypassing the regulator. It’s used when the regulator isn’t delivering breathable air—an emergency situation where you still need to get air to your mask. That’s why the correct scenario is an emergency involving a malfunctioning regulator. It isn’t meant for clearing condensation, cooling the facepiece, or handling hazardous materials incidents.
