What does a secondary device typically do?

A secondary device is typically designed to hinder rescue efforts by targeting first responders. This tactic is often employed in scenarios involving explosives or other hazardous situations, where the primary device may first create chaos and then, once responders arrive, a secondary device can detonate or activate, inflicting harm on those who come to help. Understanding this concept is crucial for first responders and emergency management professionals as it underscores the importance of maintaining vigilance and situational awareness when responding to incidents that may involve the possibility of secondary threats. The awareness of such tactics helps ensure that responders can take the necessary precautions to safeguard their safety and effectively manage the incident at hand.
