Which method can be used to assist a passenger during an evacuation?

Using the method of grasping under the arms or ankles is effective for assisting a passenger during an evacuation because it provides a stable and secure way to help someone who may be unable to move quickly or may be injured. This technique ensures physical support while maintaining control over the person's movement, which is especially important in an emergency where panic can occur.

By using this method, you can safely guide the individual towards the exit while helping to prevent them from stumbling or falling. This direct assistance not only helps the person in need but also contributes to the overall safety of the evacuation process by keeping the flow of movement organized and efficient.

Other methods might involve less secure assistance or could create further complications in a chaotic situation. For instance, pushing a passenger may cause them to trip or fall, leading to injury or panic. Asking a passenger to follow without any support might not provide the necessary help for those who are disoriented or incapacitated, and crouching behind them does not effectively address the immediate need for physical assistance while evacuating.
