It was meant as an emergency way to cut off airflow into the cabin from the engine in the event of a catastrophic turbine or engine failure leading to hot oil/toxic fumes/other nasties entering the cabin. It's use at high altitude would obviously mean you would not maintain pressurization, but that would be down on the list of priorities at just that moment (still something to keep in mind). So, I have mine right there below the throttle quadrant with a big red knob on it--and hopefully will never use it...
