When an incident expands, what is the protocol regarding functions and positions?

When an incident expands, the protocol is to fill only the functions that are necessary for the incident's current scale and complexity. This approach aligns with the flexible and scalable nature of the Incident Command System (ICS), which is designed to adapt to the evolving needs of an incident.

As incidents grow, not every previous position may be required to effectively manage the situation. By focusing on the functions that are essential for the current operational period, resources can be used more efficiently, and the command structure remains manageable. This allows for an efficient deployment of personnel and resources without creating unnecessary layers of management or overwhelming the command system.

Maintaining only the necessary functions supports situational awareness and promotes effective coordination among responders, which is crucial in dynamic incident environments. It ensures that the response remains agile, and that only critical roles are filled to meet the demands of the incident as it develops.
