What is the main difference between a formal and informal IAP?

The distinction between formal and informal Incident Action Plans (IAPs) largely revolves around the complexity and the scale of the incidents they are designed to address. A formal IAP is typically employed in larger, more complex situations where multiple resources and personnel are involved, requiring detailed coordination and clear assignments for safety and operational effectiveness. It usually includes thorough documentation, objective statements, and is developed through established protocols.

In contrast, an informal IAP is used for smaller or less complex incidents where the oversight and coordination needs are less stringent. These plans can be more flexible and may arise spontaneously, adapting to the situation as it unfolds without the necessity for extensive formal procedures.

Understanding this difference is crucial for responders, as it influences how they approach incident management and resource allocation in varying scenarios.
