More than 200 Ahura Scientific (Wilmington, Mass.) FirstDefenders have been delivered as part of the U.S. Department of Homeland Security's 2007 Commercial Equipment Direct Assistance Program. FirstDefender identifies unknown solids and liquids, including explosives, chemical warfare agents, toxic industrial chemicals, narcotics, white powders and more. In its first year as part of CEDAP, FirstDefender was offered as a bundle with MSA's Sirius Multigas Detector in the CEDAP Chemical Detection Kit, with more kits requested and awarded than any other equipment offered in the chemical detection category, Ahura Scientific said.
