Background: A conceptual model is always a suitable way to show the relationship between the different components of a process or among different processes. In the field of incident management, there are several models. However, there is almost no simple, natural, conceptual model to show the relationship between disaster risk management.

Methods: Because of the need for the development of a simple model that can quickly and at a glance relate the overall steps and components of the risk management process and various phases of disaster management, this model has been invented based on the evaluation of previous studies and reviewing current literature as well as refining the research and innovation done by the authors.

Results: In this article, a new model, which is called the Egg model, including the shell, the white (albumen) and the yellow (yolk) parts, is introduced. In which, risk management includes three steps. The first step is the assignment of a body, either a person, team or organization, as responsible (the resembling the shell). In the second step, the body does the assessment of the risk (resembling the white part). Risk assessment, on its own, includes risk identification, risk analysis, and risk evaluation. Finally, (resembling the yellow part), treatment of the risk(s) is begun which includes, prevention and mitigation, and preparedness before the disaster and, response and recovery after the disaster occurrence. Obviously, without an intact shell, the whole egg (albumen and yolk) will decay and all resources will be lost. Also without assessment of the risks, proper and effective management of the disaster is almost impossible. The third step of the risk management, the risk treatment, is in fact the disaster management.

Conclusion: This simple model shows the relationship between risk management and risk treatment. Although this model may have oversimplified the process of Risk Management, it helps to create a unique overview and understanding for almost everyone
