How long does the oxygen supply last in an emergency situation aboard a 737?

• A. 5 minutes
• B. 8 minutes
• C. 12 minutes
• D. 20 minutes

Answer: (C)

The correct answer is that the oxygen supply typically lasts for about 12 minutes in an emergency situation aboard a 737. This duration is designed to provide adequate time for the crew to manage an emergency descent to a safe altitude where breathable air is available. In the event of cabin depressurization or other emergencies requiring supplemental oxygen, the 12-minute duration allows for situations where the aircraft may need to descend rapidly, enabling the crew to maintain passenger safety as the aircraft reaches a breathable environment. Therefore, it's crucial for flight attendants to be aware of this timeframe to effectively communicate and manage the situation with passengers during an emergency.
