NYC Subway Study Will Test Impact of a Chemical Attack

(TNS) — The Department of Homeland Security is testing airflow inside the city’s subway system this week as a way to predict what would happen in a possible chemical attack.

The week-long study poses no risk to the public, the Department of Homeland Security said.

From May 9 through May 13, DHS said officials will be releasing harmless, non-toxic gases inside several subway stations in Manhattan, including Penn Station, Grand Central Terminal and at Times Square.

“This study is part of the department’s ongoing commitment to preparedness and the shared responsibility of protecting the nation’s critical infrastructure,” DHS S&T program manager Dr. Donald Bansleben said in a statement. “The results of this study will provide us with a greater understanding of airflow characteristics, informing the research and development of next generation systems that continue to ensure the safety and security of the general public.”
