False Alarm Triggers Lockdown at the Pentagon Over Hazardous Materials Concern

On Thursday, the Pentagon experienced a lockdown and partial evacuation due to a false alarm from a hazardous materials sensor that mistakenly indicated the presence of anthrax. The incident prompted precautionary measures, including a shelter-in-place order for affected areas, as emergency response teams were deployed to assess the situation. The lockdown affected multiple floors and corridors, particularly those housing key offices such as the Navy's public affairs office. Pentagon officials confirmed that the air quality issue was being investigated and that additional testing could take one to two hours. This incident underscores the importance of rapid response protocols in the face of potential biological threats.

Key Details: • Lockdown initiated on Thursday, with affected areas including floors two to five. • Response teams from Arlington County Fire Department and Pentagon Force Protection Agency were on-site. • Testing for air quality issues may take one to two hours. • Police in the building utilized gas masks and protective gear during the response.
