Prior to flights above 25,000 feet, what must a crewmember do?

• A. Review safety regulations with passengers
• B. Instruct passengers on oxygen use
• C. Conduct a cabin security check
• D. Demonstrate emergency exits

Answer: (B)

Before flights above 25,000 feet, it is essential for crewmembers to instruct passengers on oxygen use. This requirement stems from the fact that at higher altitudes, the human body is at risk of hypoxia due to lower air pressure and oxygen levels. Properly educating passengers on how to utilize oxygen masks ensures that they know what steps to take in the event of a decompression event or other situations that necessitate supplemental oxygen. Instructing passengers on the correct use of oxygen masks is vital for their safety and can be lifesaving. The focus is not only on the mechanics of how to put on the mask but also on the importance of donning it promptly, as passengers may only have a short amount of time to secure oxygen before losing consciousness. While reviewing safety regulations, conducting cabin security checks, and demonstrating emergency exits are all important aspects of pre-flight procedures, the specific emphasis above 25,000 feet is on ensuring that passengers are fully aware of how to use oxygen equipment effectively. This protocol prioritizes passenger safety during flight operations in environments where oxygen levels can become critically low.
