Which is a measure used to limit access during an IED situation?

In the context of managing an improvised explosive device (IED) situation, establishing a cordon is a critical measure used to limit access to the area where the potential threat exists. A cordon involves creating a physical barrier around the location of the IED to restrict entry and ensure the safety of civilians and responders. This approach prevents individuals from inadvertently entering a dangerous area and helps maintain control over the scene, allowing responders to focus on neutralizing the threat without the risk of further casualties or complications.

A cordon effectively secures a perimeter and can also facilitate emergency response efforts by directing necessary operations while keeping unauthorized personnel at a safe distance. By controlling access around an IED, responders can better manage the situation and minimize risks associated with possible detonation.

Confirming the presence of an IED is essential for making informed decisions but does not actively limit access; it is part of the assessment process. Controlled evacuation is critical for protecting individuals in the vicinity but typically follows the establishment of a cordon. Clearance operations are aimed at neutralizing or removing the IED but do not inherently create access limitations. Hence, the establishment of a cordon is the most effective measure in this context to ensure safety and effective management of the situation.
