What are the immediate actions during a cabin depressurization?

• A. Don oxygen masks, fasten seat belts, secure crew and passengers, and communicate with the cockpit for an emergency descent.
• B. Continue service while the cabin pressure equalizes.
• C. Inform passengers to remove masks after they feel relief.
• D. Wait for the captain's order before acting.

Answer: (A)

During cabin depressurization the priority is to restore breathable air and control the situation quickly. Oxygen masks must be donned immediately to prevent hypoxia, with crew members putting theirs on first so they can safely assist others and manage the emergency. Securing seat belts keeps everyone in place as the aircraft descends and turbulence can occur during a rapid descent. At the same time, the crew should secure passengers and themselves to maintain order and safety. Communication with the cockpit is essential to coordinate an emergency descent to a safe altitude with adequate oxygen for all aboard. This sequence prevents chaos, preserves life, and allows the flight crew to regain control.

Continuing service during depressurization ignores the urgent need for oxygen and a controlled descent, which is unsafe. Instructing passengers to remove masks after feeling relief defeats the purpose of immediate oxygen access. Waiting for the captain's order before acting would delay actions that flight attendants are trained to take right away.
