What is the main use of a megaphone in an emergency situation?

In an emergency situation, the primary role of a megaphone is to facilitate clear and loud communication when it matters most, especially during evacuations or if a public address (PA) system becomes inoperative. A megaphone allows the individual in charge to effectively reach large groups of people without relying on electronic systems that may fail or become compromised during emergencies. Its portability and direct communication capabilities make it invaluable for providing instructions, alerts, or safety information.

Using a megaphone during evacuations ensures that vital messages can be conveyed swiftly and clearly, helping to maintain order and prevent panic among individuals who may be evacuating. The nature of emergencies often requires immediate responses and effective communication, and a megaphone serves as a reliable tool to achieve that goal.
