unit designed and fabricated by ECBC staff, was integrated with the Big Mac II after its installation. This glove box, as described by David McCaskey, ECBC engineering technician, required plywood mockup fixtures to be built and transported through the building to ensure the actual glove box components could be transported into the lab for assembly. "One new thing for us was the primary zone, one of the three sections of the glove box. It is so large a fire-retardant room had to be built within the lab first so this section could be welded, ground, and polished right on-site," said McCaskey. Operation of such a large piece of equipment is challenging in and of itself. Due to its height and length, four people are needed when conducting tests in the Big Mac II. Full Immersion The Big Mac II is a culmination of 19 years of work and experience; its predecessor, the Big Mac I glove box, became operational in 2001. "We have been on a learning curve in the creation of these facilities and our goal has always been to work in as safe a manner as possible, and now we have the capability of doing full immersion aerosol testing in the Big Mac II," said Carpin. With the necessary approvals in place, the toxicology team began conducting live-agent tests in the Big Mac II in May. Detecting chem-bio threats Ensuring sensor and PPE effi cacy Advancing medical countermeasures Improving armor and energetics Modeling WMD risks The Big Mac II can be used to manipulate equipment for the testing and safe-handling of extremely hazardous chemicals.
