Our hero unplugs the air hose from the pneumatic piston. Losing pressure, the lift slides all the way down to the floor below. But the pole should still be easy enough to slide down in an emergency, if you don't care about getting back up again. With a hiss and then a metallic click, the pressurized air unlocks whatever mechanism was securing the hatch shut.
What would you have our hero do next?
Stay Cozy!
