What is the first action taken when "Oxygen Masks - Remove" is announced?

When the announcement "Oxygen Masks - Remove" is made, the first action to be taken is to check for injuries. This step is crucial because the activation of oxygen systems typically indicates that there may be a loss of cabin pressure, which could have led to a variety of injuries among passengers due to sudden cabin decompression. Assessing passenger safety and well-being is a priority in this situation, as it helps the crew ensure that all individuals are accounted for and any medical needs are addressed promptly.

This action sets the foundation for managing the emergency effectively. By determining if there are any injured passengers, the cabin crew can prioritize assistance based on severity and start providing needed care. Following that, other actions such as reassuring passengers or preparing for an emergency landing can be addressed, but the immediate focus should be on ensuring the safety of all individuals onboard.
