Final answer:
The first resource to consult if outside assistance is needed would be the local emergency response plan. The National Response Plan and the National Incident Management System are broader frameworks that provide guidance for emergency response at the national level. The incident action plan is a tactical plan developed during an incident.
Step-by-step explanation:
The first resource to consult if outside assistance is needed would be the local emergency response plan. This plan is specific to the local area and provides guidance on how to respond to emergencies and coordinate resources.
The National Response Plan (NRP) and the National Incident Management System (NIMS) are broader frameworks that provide guidance for emergency response at the national level. These plans may be consulted if the local plan is insufficient or if additional resources are needed.
It is important to note that the incident action plan (IAP) is a tactical plan developed during an incident and outlines specific objectives, strategies, and resources needed to achieve those objectives. While the IAP is important, it is typically developed based on the guidance provided by the local, national, and regional response plans.
