What are established to divide an incident into physical or geographic areas of operation?

Divisions are established to divide an incident into physical or geographic areas of operation, which allows for better management and organization of resources at an incident scene. Each division is typically responsible for specific tasks or operations within its designated area, ensuring that all parts of the incident are effectively covered and managed.

The use of divisions helps in coordinating efforts among various teams and resources, leading to improved response times and more efficient resolution of the incident. This structure also allows command personnel to maintain oversight over large scenes by assigning division leaders who communicate directly with incident command.

In contrast, sections would usually refer to larger organizational units that oversee divisions, and units and teams are typically smaller groups with specific tasks but do not inherently represent a geographic area of operation. Thus, the choice of divisions as the correct answer provides clarity in the context of incident management practices.
