What does the regulator keeper do?

The regulator keeper is designed to ensure that the regulator remains secure and properly positioned when not in use. It serves as a safety feature that helps prevent accidental disconnection or damage to the regulator, which is a critical component of the SCBA system. By securing the regulator in place, the keeper contributes to the overall effectiveness and reliability of the SCBA, ensuring that it functions as intended during use.

While controlling airflow and acting as a pressure gauge are essential functions of the SCBA's regulator, these specific functions are not performed by the regulator keeper. Additionally, mounting to the oxygen tank is a function that relates to the overall assembly but does not reflect the specific purpose of the regulator keeper.
