The oxygen system manual shutoff valve is located on which bulkhead side?

Explanation:
The oxygen system manual shutoff valve is placed on the right-hand aft side of the FS 245 bulkhead to maximize quick, easy access from the crew area while keeping the valve out of the forward equipment zone and in line with the oxygen line routing. RH (right-hand) is defined from the cockpit looking forward, and aft points toward the tail, so this position sits toward the back on the starboard side. This arrangement helps ensure rapid isolation during emergencies without interfering with other systems or components in the fore fuselage. If the valve were on the left or fore side, accessibility and routing would be less optimal, potentially delaying shutoff.
