Scientists and engineers at the U.S. Army Edgewood Chemical Biological Center can now fully immerse large pieces of chemical protection and detection equipment in aerosolized chemical environments thanks to the development of a one-of-a-kind glove box. The glove box, dubbed the Big Mac II, has been created at ECBC to be used for the testing and safe-handling of extremely hazardous chemicals. Its expanded internal 1,000 liter exposure chamber allows for full immersion aerosol testing under a range of environmental conditions and fills a much-needed requirement to test large-footprint items The development and fabrication of the Big Mac II was funded by both the Product Director Cross Commodity Advanced Threats and Test Infrastructure and the Defense Threat Reduction Agency. "The goal for the McNamara glove box facilities is to provide the necessary toxicological and performance data to help maintain the warfighter in a readiness state. Whatever may be encountered on the battlefield, the Soldiers need to know the nature of the hazard they face and the means necessary to protect themselves," said John Carpin, Ph.D., ECBC biomedical engineer. Setting the Stage The Big Mac II includes environmental controls with the capability to change the temperature over a range of -20 to 50 degrees Celsius and humidity conditions from 5 to 95 percent within the internal test chamber. The environmental conditioning system, which is a separate A one-of-a-kind glove box facility, dubbed the Big Mac II, has been crafted and created at ECBC to be used for the testing and safe-handling of extremely hazardous chemicals. (ECBC) MAXIMIZING THE TOXICITY COEFFICIENT Glove box allows Edgewood Chemical Biological Center (ECBC) to conduct in-depth toxicology research on a larger scale.
