Establishment Of The ICS Modular Organization Is The Responsibility Of The:

The establishment of the ICS modular organization is the responsibility of the Incident Commander.

Incident Commander has the authority to structure the response team according to the needs and complexity of the incident. The modular organization allows for flexibility, enabling the Incident Commander to add or remove roles as required. This ensures that the response is tailored to the specific situation, whether it’s a small local emergency or a large-scale disaster.

During a wildfire for example, the Incident Commander might initially establish a small team to assess and contain the fire. As the fire spreads, the Incident Commander could expand the organization to include additional teams for evacuation, medical support, and coordination with other agencies. This modular approach ensures that the response is scalable and can adapt to the changing conditions of the incident.
