When a crisis occurs, such as a fire in a chemical facility, difficult decisions need to be made based on assessment of risk. Is it safe enough for re-sponders to enter the area? Do we need to evacuate the public from the nearby area? Assessing risks may require information from a number of different sources, as well as collaboration across organizations and management levels. In this paper we present ongoing work to develop a collaborative tool to support risk analysis in crisis situations. The tool will be tightly integrated with a com-plementary tool to make coordinated situation assessments, planning, decision making, information gathering and sharing, thereby providing a unified and in-tegrated crisis management support facility.
