Where will you find an additional oxygen mask on all CRJ 700 aircraft?

On all CRJ 700 aircraft, an additional oxygen mask can be found in the A/CR (Crew Rest) area. The presence of this additional mask is crucial for enhancing the safety and preparedness of the crew during emergencies, ensuring they have access to supplemental oxygen if needed while performing their duties or resting in the crew rest area.

The layout of the aircraft is designed to provide easy access to critical safety equipment, and the inclusion of an oxygen mask in the A/CR underscores the importance of crew safety and the need to maintain high operational standards in case of a decompression or other in-flight emergencies. The other options, representing different crew rest areas on the aircraft, do not typically house this additional safety equipment, which is strategically placed to best serve the crew's readiness in emergencies.
