Government to Study Chemical Threat to Subways

The feds will spend a week in city subway stations trying to figure out how vulnerable they are to chemical or gas terrorist attacks.

The Department of Homeland Security will stage several simulated airborne particle attacks in Grand Central, Times Square and Penn stations from Monday to Friday.

The tests will involve sending inert tracer particles into the air at the three stations and seeing how quickly they can spread over platforms, trains and stairwells.

“This study is part of the department’s ongoing commitment to preparedness and the shared responsibility of protecting the nation’s critical infrastructure,” said DHS security manager Dr. Donald Bansleben.
