Hello Gizmo,
good points, common sense, right.👍
I agree as long as you/we get the Oxygen masks on right away. Dont wait.
My humble opinion is cockpit VOC sensors should be installed, as they are on DHL 757 aircraft.
putting forth a scenario here...
If the crew did not smell the fumes, which can happen with Formaldehyde and other VOCs and poor sense of smell and then became incapacitated then the crew would be in danger, thus the aircraft.
