What document typically outlines the responsibilities of each unit in an incident?

The Incident Action Plan (IAP) is crucial in incident management as it provides a framework for operational objectives and delineates the responsibilities of each unit involved in the incident response. This document is formulated during the planning section of the incident, ensuring that all participating units are aware of their specific roles, tasks, and timelines.

The IAP is structured to facilitate effective coordination and communication among various units, making it clear who is accountable for what actions during the incident. Its detailed nature helps in ensuring that all aspects of the incident response are organized and that resources are allocated efficiently toward achieving the incident's objectives.

In comparison, a Resource Deployment Plan focuses on the logistics of resource management rather than outlining unit responsibilities, while a Safety Assessment Report primarily addresses hazard identification and safety protocols rather than operational tasks. An After Action Review serves as a retrospective analysis of the incident to identify successes and areas for improvement, rather than a plan to govern the current response effort. Thus, the IAP is the essential document for defining roles and responsibilities during an incident.
