How many Portable Oxygen Bottles (POBs) are on the CRJ 200?

Explanation:
Two portable oxygen bottles are provided on the CRJ 200. These bottles give a quick, personal oxygen source for crew members and can be used to assist a passenger in a medical situation when the fixed, wall-mounted oxygen masks aren’t suitable or during a period when the main system isn’t immediately available. Having two ensures redundancy for the two flight crew members and provides an available supply if one bottle is in use or needs servicing. While passengers rely on the fixed oxygen system with masks during depressurization, POBs serve as a backup resource for crew and medical needs, so the CRJ 200 is equipped with two.
