The essentials
Pentagon lockdown in Arlington triggered by detected air quality concern; hazmat teams responded.
The Pentagon initiated a lockdown affecting floors 2-5 in corridors 4-7 after detection of an air quality issue at its Arlington, Virginia headquarters. The Pentagon Force Protection Agency and Arlington County Fire Department responded to the incident, treating it as a hazardous materials situation.
The targeted lockdown, rather than a facility-wide shutdown, suggests the issue was geographically contained. Emergency responders assessed the air quality concern and managed the evacuation and response procedures. The specific nature of the detected air quality issue was not detailed in available reports.

Partial lockdown limits disruption while hazmat teams investigate
