At what cabin pressure will oxygen masks automatically deploy on all CRJ aircraft?

Oxygen masks on all CRJ aircraft are designed to automatically deploy when the cabin pressure altitude exceeds 14,000 feet, within a range of plus or minus 500 feet. This operational threshold ensures that passengers and crew have access to supplemental oxygen in the event of a depressurization during flight, which can result in inadequate oxygen levels available for normal respiration. The automatic deployment of oxygen masks helps to safeguard against hypoxia, which is a reduced level of oxygen in the blood and can lead to loss of consciousness if not addressed promptly. The choice of this altitude is part of safety regulations and operational standards intended to enhance passenger safety during high-altitude flight.
