In disaster management, which command system is commonly used to coordinate multiple agencies?

• A. National Response Framework
• B. Unified Command System
• C. Incident Command System
• D. Emergency Management Office

Answer: (C)

Coordinating several agencies at a disaster scene requires a single, scalable command method that everyone can follow. The Incident Command System provides that framework. It creates an on-scene, adjustable structure with clearly defined roles—like who leads the operation, who handles planning, logistics, and finance—so responders from police, fire, EMS, public works, and other groups can work together without duplicating effort or stepping on each other’s toes. It also uses common terminology, standardized procedures, and a shared planning process, which helps different agencies communicate quickly and coordinate actions effectively.

When more than one agency or jurisdiction is involved, Unified Command fits within this system to ensure joint decision-making and equal participation from all parties, while the overall approach remains the Incident Command System. Other options don’t provide the same on-scene, cross-agency coordination structure: a national framework guides broader policy and coordination at higher levels, and terms like Emergency Management Office aren’t the standardized system used for incident coordination.
