What is the first step to take before opening any aircraft door?

The first step to take before opening any aircraft door is to assess the situation outside the aircraft. This critical initial assessment ensures that it is safe to open the door, considering any potential hazards or obstructions. By conducting this assessment, crew members can identify dangers such as fire, smoke, or other emergency situations that may affect passenger safety and necessitate immediate action.

The assessment allows flight attendants and crew to make informed decisions on whether it is safe to proceed with opening the door. It ultimately helps protect the well-being of passengers and crew by ensuring that all safety protocols are followed before any actions that could impact aircraft safety are taken.
