What direction should the bypass knob be turned to ensure it is fully closed?

The bypass knob on the MSA G1 Self-Contained Breathing Apparatus (SCBA) is designed to allow or restrict airflow through the device. Turning the knob in the correct direction ensures that it is fully closed, preventing any air leakage and maintaining the integrity of the breathing apparatus.

Turning the bypass knob clockwise engages the mechanism that secures the flow of air, establishing a seal that keeps the air from escaping. This is essential in situations where the user needs to rely on the SCBA for a continuous supply of breathable air while operating in hazardous environments.

Additionally, it's important for the user to familiarize themselves with the SCBA's operation and maintenance procedures to ensure optimal performance and safety during use. Properly configuring the bypass is a critical step in the preparation of the equipment for deployment.
