A new self-assessment tool provides hospitals with a means of evaluating decontamination plans and capabilities against current regulatory standards, recommendations from subject matter experts, and national and international health care decontamination best practices. The Hospital Decontamination Self-Assessment Tool helps hospitals plan for, and respond to, small and large-scale incidents requiring the decontamination of patients contaminated by or exposed to chemical, biological, radiological, or nuclear agents. The tool is intended for use by hospital emergency preparedness planners, hospital decontamination team members, and other personnel with a responsibility for their facility’s decontamination plans and procedures.
