Incident Command & Coordination
ICS Structure
About this lesson
What the Incident Command System is, why it exists, and the four principles that keep a response organized as it grows.
Key terms
Span of control: 3 to 7 people per supervisor, 5 is ideal
Unity of command: Everyone reports to one supervisor, never two
Chain of command: Orders flow through the ICS structure, not by rank
Modular organization: Activate only the parts the incident needs
