What is the purpose of the shoulder strap during portable oxygen bottle operation?

• A. To secure the bottle to the body
• B. To measure oxygen flow
• C. To operate the valve
• D. To attach to aircraft frame

Answer: (A)

The shoulder strap is there to secure the portable oxygen bottle to the body. Keeping the bottle attached and stable prevents it from shifting, slipping, or dropping during movement, turbulence, or while you’re multitasking with passenger care. That stability also helps keep the regulator and flow setup in a consistent, easy-to-read position so you can manage oxygen supply reliably without fumbling. The strap isn’t involved in measuring oxygen flow, operating the valve, or attaching the bottle to the aircraft frame. Those tasks are handled by the regulator and valve controls and by how the equipment is designed to be stowed or secured when not in use.
