What acronym refers to the responsibilities within the confines of a single command structure?

The acronym that refers to the responsibilities within the confines of a single command structure is ABC FEEDS. This acronym serves as a mnemonic device that helps individuals remember the key components and responsibilities in incident command, particularly ensuring that all functions within a team or operation are properly managed under one command structure.

Each letter in ABC FEEDS corresponds to specific responsibilities such as Accountability, Building safety, Coordination, Fire suppression, Emergency medical services, Decontamination, and Safety. This clarity in command structure is crucial in emergency response contexts, as it streamlines operations and enhances efficiency, ensuring that everyone understands their roles within the operation.

The other options represent different concepts or frameworks that do not specifically pertain to responsibilities within a single command structure, making ABC FEEDS the most appropriate choice.
