The Pentagon went into lockdown Thursday over an “air quality issue” that may have been a false alarm.
Hazmat teams rushed to the defense facility after its systems detected an “air quality issue necessitating precautionary measures until we determine its significance,” Pentagon spokesperson Sean Parnell told The Independent on Thursday morning. But sources told CNN the response may have been triggered by a false alarm.
“The Department is executing standard protection protocols, including a shelter-in-place order for the affected area. Response teams are in place and ready to support building occupants,” Parnell said.
The shelter-in-place order was still in effect as of 12:24 p.m. local time, according to the Pentagon Force Protection Agency.
Some people were evacuated from the facility, CNN reports. A source told the network they spotted police wearing protective gear, including gas masks. The Arlington County Fire Department confirmed its units were assisting the Pentagon Force Protection Agency’s hazmat team.
