No hazard found after ‘severe’ Pentagon alert sparks emergency response –A reported hazmat incident triggered a shelter-in-place order that has since been lifted | 10 June 2026 | Certain areas in the Pentagon went on lockdown Thursday morning due to an “air quality incident” that was later revealed to be a false alarm. An alert, shared with Fox News Digital, carrying a “severe” rating was sent to employees in multiple corridors of the building directing them to shelter in place. All other personnel were told to avoid the area. As of 1:30 p.m. Eastern Time Thursday, the lockdown order was lifted, according to Pentagon officials. “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 spokesperson Sean Parnell said in a Thursday statement.
