Pentagon Enters Lockdown Mode Over False Alarm

The Pentagon had multiple floors locked down and evacuated Thursday over an air quality false alarm.

“Earlier this morning, Pentagon occupants were notified ‌of ⁠a potential air quality issue, prompting immediate precautionary safety measures and evaluation. Subsequent testing confirmed no hazard exists, and normal operations have ​resumed,” ​chief Pentagon ⁠spokesman Sean Parnell said. “We express our sincere appreciation to the first responders ​for their swift actions to ensure ​the ⁠safety of all personnel.”

Parnell had originally reported there was an “air quality issue necessitating precautionary measures.” Floors two through five in corridors four through seven were closed down, and the Arlington Fire Department’s hazmat team was also present.
