Gas Release Simulated in New York Train Station
The U.S. Homeland Security Department last month used a nontoxic gas to test how vapor might spread through the Grand Central Terminal in New York City following a WMD attack, the New York Daily News reported today (see GSN, March 9). Scientists from four national laboratories participated in the exercise from June 26-30. Gas was released to establish how its circulation was affected by different factors, including the movement of people. “If there was some kind of emergency — smoke or who knows what — released in Grand Central Terminal, we want to know how it's going to move around and how best to evacuate it,” said Marjorie Anders, a spokeswoman for rail line Metro-North. “Everybody knows that some kind of biological, chemical or radiological threat is something we have to plan for, and this is part of that planning.” The data gathered from the test will be used to improve response to an attack and to prepare other transportation stations throughout the country. It might also be used to change ventilation, heating and air conditioning systems at Grand Central, the Daily News reported (Pete Donohue, New York Daily News, July 7).
