Where is the oxygen system manually operated shutoff valve located?

Explanation:
The oxygen system’s manually operated shutoff valve is placed on the right-hand aft side of the FS 245 bulkhead. This location gives quick, reliable access from the crew area to isolate the main oxygen supply, which is essential during maintenance or in an emergency. Placing the valve here also aligns with the typical routing of the oxygen lines around that bulkhead, keeping the shutoff in the primary feed line and away from forward-area clutter. Aft-right positioning balances accessibility with safety and system layout, whereas a left-hand or forward location would be harder to reach or not in line with the main oxygen plumbing.
