Step-by-step explanation:
The Incident Command System (ICS) should be used at all types and sizes of incidents as it provides a systematic and scalable approach to incident management.
ICS is particularly important in emergency situations, such as natural disasters, terrorist attacks, or large-scale accidents, where multiple agencies and organizations need to work together to respond effectively.
By implementing ICS, incident commanders can establish a clear command structure, coordinate resources, and communicate efficiently, ensuring a coordinated and effective response to any incident.
