For every large emergency incident, there must be:

• A. An incident action plan
• B. Rescue mode
• C. A unified command
• D. A financial report

Answer: (A)

A structured plan that guides operation objectives and resource use is essential in a large emergency. The Incident Action Plan is the primary document that sets the incident objectives for a defined period, outlines strategies to achieve them, assigns tasks and resources, and includes safety and communications details. This single plan keeps all responding agencies synchronized, helps anticipate needs, and allows the incident commander and staff to monitor progress and adjust as conditions change. In large incidents, having a documented plan ensures everyone is working toward the same goals and methods, which is why this is the best answer.

Rescue mode describes a tactical approach within operations, not a formal, overarching plan required for the incident. Unified command is used when multiple agencies with jurisdiction are actively involved; while common in multi-agency responses, it isn’t mandated for every large emergency. A financial report isn’t part of the standard incident management process.
