Which of the following actions is NOT allowed for cabin crew during an emergency?

The action of pouring liquids onto the floor is not allowed for cabin crew during an emergency because it can create additional hazards. Spilled liquids can lead to slips and falls, increasing the risk of injury to both passengers and crew members during a chaotic situation. Maintaining a safe environment is paramount, particularly in emergencies where every second counts.

On the other hand, shouting emergency commands is an essential part of managing an emergency, as clear and loud instructions help guide passengers effectively. Redirecting passengers is also crucial to ensure they move to designated safe areas, and alerting the flight crew about the situation is vital for coordinating an adequate response to the emergency. Thus, maintaining safety protocols and preventing further risks is the priority in emergencies, making pouring liquids onto the floor an inappropriate action.
