Pentagon Partly Confined After Air-Quality Anomaly

Overview

• The Pentagon, which was placed under confinement Thursday, said building safety systems detected an air-quality problem that led officials to order confinement of a zone and multiple floors.
• Local firefighters and specialized hazmat response teams were dispatched to the scene and remain on site to support occupants and contain any hazard.
• Pentagon spokesperson Sean Parnell said tests are underway to identify the substance and that initial testing could take about one to two hours.
• Officials have not reported injuries or disclosed a definitive cause and are following standard protection and continuity protocols while the situation is assessed.
• The Pentagon uses automated environmental sensors that trigger precautionary measures for occupant safety and continuity of Department of Defense operations, and authorities say they will update the public as test results become available.
