ICS-100 Course Q&As

  1. What is the Incident Command System (ICS)?

    • Answer: The Incident Command System (ICS) is a standardized approach to the command, control, and coordination of emergency response providing a common hierarchy within which responders from multiple agencies can be effective.
  2. Why was the Incident Command System developed?

    • Answer: ICS was developed in the 1970s following a series of catastrophic fires in California to address response problems often attributed not to lack of resources or failure of tactics but to inadequate management of incidents.
  3. What are the five major functional areas of ICS?

    • Answer: The five major functional areas of ICS are Command, Operations, Planning, Logistics, and Finance/Administration.
  4. What is the primary goal of using ICS?

    • Answer: The primary goal of using ICS is to ensure the safety of responders and others, achieve incident management goals, and use resources efficiently.
  5. How does ICS enhance the response to incidents?

    • Answer: ICS enhances the response by organizing and coordinating personnel, facilities, equipment, and communications, establishing a clear chain of command, and allowing agencies to work together towards common objectives efficiently.
  6. What is the role of an Incident Commander?

    • Answer: The Incident Commander has overall responsibility for managing the incident by setting objectives, assigning tasks, and allocating resources effectively.
  7. How does the modular nature of ICS help in incident management?

    • Answer: The modular nature of ICS allows the organizational structure to expand or contract based on the size and complexity of the incident, ensuring it remains manageable and effective.
  8. What is meant by “Unified Command”?

    • Answer: Unified Command is a structure that allows agencies with different legal, geographic, and functional responsibilities to work together effectively without losing their individual authority.
  9. How does ICS promote effective communication during an incident?

    • Answer: ICS promotes effective communication by using common terminology, establishing clear communication plans, and ensuring that information flows efficiently through the designated chain of command.
  10. What are the benefits of using ICS for planned events?

    • Answer: Using ICS for planned events, such as public gatherings or state fairs, helps manage resources, facilities, and personnel efficiently, ensuring the event runs smoothly and safely by applying the same structured approach used for emergencies.
