Researchers with Lawrence Berkeley National Laboratory (Berkeley Lab) are participating in a study sponsored by the U.S Department of Homeland Security (DHS) in conjunction with the Massachusetts Bay Transportation Authority (MBTA) to determine how airborne contaminants would spread if released into Boston's subway system. During the study, which is now underway and runs from December 5-11, the Berkeley Lab researchers will be measuring how gas gets dispersed throughout tunnels and subway cars.
"The data we're collecting will help in the development of the next generation of biological and chemical agent detector systems," says Melissa Lunden, a chemist with the Environmental Energy Technologies Division (EETD) who leads Berkeley Lab's participation. "The information will also provide a better understanding of airflow characteristics in subway systems that should be useful for planning responses to fires, unintentional chemical or fuel spills, and other emergencies."
In addition to Lunden, other Berkeley Lab EETD researchers working on this DHS study include Doug Black, William Delp, Toshifumi Hotchi, Jennifer Logue, Ann McDonagh, Richard Sextro, and Tracy Thatcher.
While Boston's MBTA subway system has never been threatened or attacked, terrorists have threatened subway systems in New York and elsewhere. In 1995, a sarin gas attack on the Tokyo subway system by domestic terrorists killed a dozen people and injured dozens more.
"Proactively studying and preparing for possible threats is one of our most effective strategies for fortifying our critical infrastructure," said DHS Secretary Janet Napolitano in announcing this study. "DHS is undertaking many studies such as this across the country to inform our emergency response planning in preparation for chemical or biological terrorist attacks."
The MBTA study involves the release of common, harmless tracer gases used for indoor and outdoor air testing (sulfur hexaf
