What does the high-pressure line in a RIT bag connect to?

The high-pressure line in a Rapid Intervention Team (RIT) bag connects to the breathing apparatus. This connection is crucial for providing an emergency supply of air to a downed or trapped firefighter. The high-pressure line allows for the transfer of air from a full SCBA cylinder in the RIT bag, ensuring that a firefighter in distress can quickly access breathable air without delay.

Understanding this function is essential in emergency scenarios where time is of the essence, as it can significantly increase the chances of survival for an individual in need of immediate respiratory support. The other options, though they might involve different systems or equipment, do not pertain to the specific role of the high-pressure line in the context of a RIT bag.
