Pentagon briefly locked down over false hazardous materials alert

The Pentagon was placed under lockdown and partially evacuated on Thursday after a hazardous materials sensor triggered a false alarm, according to two sources familiar with the situation cited by CNN.

Multiple floors and corridors inside the building had been locked down and others were evacuated due to a “hazardous materials incident,” three sources familiar and the local fire department said earlier on Thursday, News.Az reports, citing CNN.

As of 12:30pm the lockdown had not been lifted, one of the sources said.

The evacuation was triggered when a Pentagon sensor system detected the possible presence of anthrax, according to first responder radio traffic and a source familiar with the incident. But the sensor system was malfunctioning, one of the sources familiar said, causing the false alarm.

Pentagon spokesman Sean Parnell said that systems within the Pentagon had “detected an air quality issue necessitating precautionary measures until we determine its significance.”

“The Department is executing standard protection protocols, including a shelter-in-place order for the affected area,” Parnell said. “Response teams are in place and ready to support building occupants.”

Internal guidance sent by the Pentagon’s security team said an “air quality issue” had been detected and additional testing was needed.

“This additional testing could take one to two hours,” the message said. “Response teams are in place and ready to support building occupants if necessary. You may observe response personnel from multiple agencies and precautionary measures taking place in the center courtyard. Please do not interpret these activities.”

The Arlington County Fire Department sent units to assist the Pentagon Force Protection Agency’s hazardous materials response team, according to fire department spokesperson Capt. Jamie Jill.

A post on social media from the Arlington Fire & EMS said Arlington County Fire Department Hazardous Materials Team were operating at the Pentagon “during a hazardous materials incident.”

Floors two through five in corridors four through seven of the sprawling Pentagon complex were locked down, two of the sources said. Floors two through five are the above-ground floors of the Pentagon; there are nine corridors total in the building. Offices within the impacted area include the Navy’s main public affairs office and the Secretary of the Army’s office.
