At what altitude do oxygen masks automatically deploy on all CRJ aircraft?

Oxygen masks on CRJ aircraft automatically deploy at an altitude of 14,000 feet due to the regulations set for passenger safety in the event of cabin depressurization. At elevations over this height, the air pressure decreases to levels where it can cause hypoxia, a condition that results from insufficient oxygen in the bloodstream. Deploying oxygen masks at this altitude ensures that passengers have immediate access to supplemental oxygen, which is crucial for maintaining consciousness and cognitive function while the aircraft descends to a safer altitude. This standard is aligned with aviation safety protocols to provide an additional layer of protection in emergency situations, emphasizing the importance of quick measures to ensure passenger well-being as altitude increases.
