Purpose: The Hazardous Material Exercise Toolkit is designed to help individual hospitals, communities, regions and/or states assess their plans and procedures to request and deploy CHEMPACK assets and to perform decontamination of victims. Toolkit Description: The exercise toolkit is a tabletop exercise/ evaluation tool that supports emergency response planners to test and assess the response to a simulated mass casualty incident caused by chemicals requiring the deployment of CHEMPACK assets. It does so based on the following five objectives: 1. Discuss relevant protocols and procedures involved in obtaining and deploying CHEMPACK assets 2. Examine key assumptions and actions that relate to hospital based decontamination during a HAZMAT incident 3. Assess the communication systems and networks used during a large scale hazardous materials event that support field and hospital situational awareness regarding the responders' capability to respond 4. Name best practices in the flow and care of contaminated and uncontaminated patients, visitors and medical personnel to the hospital during the event 5. Identify essential recovery issues related to the incident, including the supplies, staff and resources needed to demobilize and return to normal operations Who should use it?: The exercise toolkit is intended to be used by public health officials, hospital leaders, EMS, emergency managers, individual communities, and coalitions. Ideally, groups will work together collaboratively to enhance the utility of the exercise. Benefits: By assessing the performance of the HAZMAT/CHEMPACK plans for those involved, it is hoped that this tool will improve these plans and increase performance.
