Unity of Command is defined as which description?

• A. Chain of Command
• B. Span of Control
• C. Unity of Permits
• D. Unity of Command

Answer: (D)

Unity of Command means that each responder reports to only one supervisor. This creates a single source of direction for every person on the scene, preventing conflicting instructions and ensuring clear accountability. In hazmat or emergency responses, having one supervisor per person helps speed decisions, reduces confusion, and keeps safety priorities consistent. It’s different from chain of command, which describes the overall line of authority, and from span of control, which concerns how many people a supervisor can manage effectively. Unity of Permits isn’t a standard term in incident management.
