If a seat safe/arm handle is left armed, what is one appropriate action to take?

Utilizing aircrew if they are still present is an appropriate action to take when a seat safe/arm handle is left armed. The presence of the aircrew enables immediate assessment of the situation and coordination for safety measures. When the seat is armed, it presents a potential hazard, especially if the aircraft is active or undergoing maintenance. The aircrew can provide expertise, assist in understanding the aircraft systems, and facilitate quick corrective actions. This collaborative approach ensures that all personnel are on the same page, minimizing risk.

The other actions may not prioritize safety adequately. Safing the seat immediately is also important, but the aircrew's involvement ensures that the correct procedures are followed. Ignoring the situation could lead to disastrous consequences, and delegating the issue to someone else without proper communication may result in the matter being overlooked or mishandled.
