What mode is the SCBA in when it is on but not clipped in?

Explanation:
When an SCBA is powered on but not clipped into the wearer’s harness, it is in stand-by mode. This state keeps the unit pressurized and ready, but it does not actively deliver air to a facepiece because there’s no inhalation trigger connected through the harness. It allows for a quick transition to full use—clip in and begin breathing, and air flow starts. In contrast, operational mode is active breathing with the wearer connected, maintenance mode is for servicing, and training mode is for practice scenarios.
