The U.S. Army Medical Research Institute of Chemical Defense is the nation’s leading science and technology laboratory in the area of medical chemical countermeasures research and development. With sophisticated laboratories located at Aberdeen Proving Ground, Maryland, the MRICD manages a diversified portfolio of medical chemical and biochemical threat agent research projects for the Department of Defense and other federal agencies. The MRICD focuses its research on medical countermeasures for nerve agents, vesicants (e.g., sulfur mustard), metabolic poisons (e.g., cyanide), pulmonary toxicants (e.g., phosgene), toxic industrial chemicals, toxins of biological origin, and pharmaceutical-based agents, as well as on approaches to mitigate the effects of exposure by removing or detoxifying chemical threats. The institute also develops, validates, and implements analytical methods to verify human chemical-threat exposures. Additionally, the MRICD, as part of its mission, provides training and education to instruct medical professionals, first responders, and operators from federal and non-governmental agencies in the medical management of chemical casualties on the battlefield and in civil disaster events involving weapons of mass destruction. The MRICD also provides consultation to military and civilian authorities in the prevention, preparation, response, recovery, and mitigation of disaster response to mass chemical casualties.
