What is an effective technique for signaling to a team during an emergency?

Using visual cues is an effective technique for signaling to a team during an emergency because visual communication can be clear, immediate, and less likely to be misunderstood than verbal signals, especially in noisy or chaotic environments. For instance, using hand signals or flags can convey specific instructions or alerts without relying on hearing, which may be compromised due to the situation.

Visual signals can also be easily recognized at a distance, allowing team members to quickly grasp the situation and respond appropriately. This method is particularly useful in scenarios where quick and decisive action is necessary, as it helps maintain clarity and organization within the team, ensuring that every member knows what to do next.

While other methods like shouting or counting down might seem effective in certain contexts, they can lead to misunderstandings or chaos, especially during high-pressure situations.
