Final answer:
Emergency operation plans feature coordinated and effective response protocols like those in NIMS 200, functioning as a crucial 'break glass in case of emergency' safeguard.
Step-by-step explanation:
An important feature of emergency operation plans, such as those referenced in the NIMS 200 framework, is that they function like a 'break glass in case of emergency' safeguard. These plans are designed to ensure coordinated, swift, and effective responses to various types of emergencies, including natural disasters, terrorist attacks, and other critical incidents. They focus on implementing civil defense and emergency preparedness measures, including anti-terrorism legislation, to maintain the resilience of critical national infrastructure. Emergency workers are trained not just in medical and technical skills but also in decision making, teamwork, communication, and stress management which enables them to respond effectively during emergencies.
