(NBC) New York City’s response plans for a chemical or biological attack will be put to the test in the coming weeks as part of a federal preparedness study.
The MTA says the Department of Homeland Security working alongside a team of researchers and city agencies will deploy a non-toxic gas this month at about 120 locations across the city.
Most of the locations will be above ground, including some parks. A number of below-ground subway stations will also be included, though details on which ones weren’t known.
The tests will be conducted on five separate days between Oct. 18 and 29.
