What is the duration of chemically generated oxygen during an emergency?

• A. 8 minutes
• B. 10 minutes
• C. 12 minutes
• D. 15 minutes

Answer: (C)

The duration of chemically generated oxygen during an emergency is typically around 12 minutes. This is important for flight attendants and crew to understand, as this duration provides essential supplemental oxygen during critical situations such as cabin depressurization or smoke in the cabin. The 12-minute timeframe is designed to offer a sufficient amount of time for passengers and crew to take necessary safety actions, such as donning oxygen masks, or for the aircraft to reach a safer altitude where breathable air is available. This knowledge is crucial for maintaining safety and ensuring that certified actions can be taken promptly during emergencies.
