What are 'secondary devices' in the context of EOD?

In the context of Explosive Ordnance Disposal (EOD), 'secondary devices' refer specifically to explosives that are strategically placed to detonate after an initial explosion. This method is often employed by adversaries as a tactic to target first responders, military personnel, or other individuals who may rush to the scene following the initial blast. The intention behind using secondary devices is to maximize casualties and confusion, increase the effectiveness of the attack, and complicate the response efforts by EOD teams and emergency services.

This understanding highlights the importance of situational awareness in EOD operations, as teams must always be alert to the possibility of secondary devices when responding to an initial incident. The awareness of this tactic shapes response protocols, such as thorough site assessments and the implementation of safety measures to protect personnel from potential follow-up explosions.
