The main idea is to create a controlled boundary that keeps the incident area separate from the rest of the facility. This involves establishing a buffer zone around the incident so access is restricted and only authorized personnel can approach, which helps prevent spread and keeps others safe. By isolating the incident in this way, responders can work more effectively within a defined space while the rest of the facility remains protected. While logging actions and coordinating with outside responders are important parts of overall incident response, the defining duty of the inner perimeter is maintaining that buffer between the incident area and the rest of the facility.
