Upon what is the incident action plan based?

• A. Information gathered during size-up
• B. Weather forecasts
• C. Past incidents
• D. Incident action templates

Answer: (A)

The incident action plan is built from the information collected on scene during size-up. That initial assessment, along with ongoing updates about conditions, hazards, and available resources, establishes the incident objectives and the strategies to achieve them, then translates into the actions, assignments, and timeline in the plan. Weather, while it can influence tactics and safety considerations, is just one input among many and does not alone define the plan. Lessons from past incidents can inform general readiness, and standard templates provide structure, but neither replaces the real-time, site-specific information gathered during size-up that drives a coordinated, safe, and effective response.
