Currently, emergency response plans generally suffer from low quality, lack of specificity and practicality. Scenario construction is crucial for the development of an emergency response plan system. Management plays a supporting and guiding role. This paper is formulated to promote scientific and practical methods for developing emergency response plans and improve the quality of such plans. The document covers scenario construction for emergency response plans at all levels and of all types. This document, based on risk assessment and aiming to improve the quality of emergency response plans, uses the "scenario-task-capability" framework as its main thread and proposes general scenarios. Scenario Construction Methodology. This method clarifies the emergency response process, responsibilities, and measures through scenario screening and development, emergency task analysis, and capability assessment. This provides scientific support for the evaluation and revision of emergency response plans. Emergency Response Scenario Construction Methods

1 Scope

GB/T 46791-2025 is the Chinese national standard covering building the scenario an emergency plan is written against - the hazard and its plausible worst case, the cascading failures, the resources unavailable because the same event took them out, and the assumptions written down so they can be challenged. A plan written against a comfortable scenario fails on the day. First edition, under the Ministry of Emergency Management. Issued on 2 December 2025, it has been in force since 1 July 2026.

This document establishes the general principles for emergency response scenario construction, and describes the process including scenario selection and development, emergency task review, and emergency capability analysis. Methods for constructing emergency response scenarios, including analysis, evaluation, and revision of emergency response plans. This document applies to scenario building activities conducted by governments and their departments during the development and revision of emergency response plans. Other organizations conducting emergency response plan development should also be aware of this application. Use this as a reference for scenario-based activities.

4 General Principles

4.1 The construction of emergency response scenarios follows the principles of being guided by improving the ability to respond to emergencies, being realistic, dynamically improving, and facilitating practical operation.

4.2 Based on a comprehensive risk assessment and a thorough review and analysis of the existing emergency response plan system, determine the needs for emergency response plan development and the specific emergency response plans. Scenario building objectives.

4.3 Emergency Response Scenario Development. This process includes scenario selection and development, emergency task review, emergency capability analysis, and emergency response plan evaluation and revision. The process is carried out, and the flowchart is shown in Figure 1.
