On June 11, according to sources cited by CNN, multiple floors and corridors within the Pentagon have been sealed off due to a "hazardous materials incident," with personnel inside the building evacuated. A hazardous materials response team is en route to the scene.
Sources also revealed that police officers on duty inside the building have donned gas masks and full chemical protective gear.
Subsequent investigations determined that the event was a false alarm caused by a malfunction in the sensor system. In the morning, the Pentagon's air monitoring system triggered an alert indicating the possible presence of dangerous substances such as anthrax, which activated the "hazardous materials incident" alert.
Immediate lockdown and evacuation: Floors 2–5 and corridors 4–7 were sealed off, with personnel either evacuated or instructed to shelter in place; on-duty police officers wore gas masks and full chemical suits.
The alert has now been lifted, and no actual hazardous substances have been found.
Key information:
Cause: The security system detected a potential presence of anthrax, but it was later confirmed that the system was faulty at the time.
During the incident, floors 2 to 5 were sealed off, on-duty officers wore gas masks and full chemical protective suits, and building occupants were temporarily required to "shelter in place."
Official response: A spokesperson confirmed that the system detected "air quality issues," but emphasized that this was purely a precautionary measure.
