Why It Matters
The Pentagon, the headquarters of the US Department of Defense, experienced a temporary "shelter-in-place" order due to a detected air quality issue. Firefighters and a Hazardous Materials Team investigated the incident.
The all clear has been given at the Pentagon, the sprawling facility that houses the US Department of Defense, after firefighters were called to investigate a “hazardous materials incident”.
Pentagon spokesman Sean Parnell said on Thursday that a “shelter-in-place order” had been issued after a possible air quality issue was detected.
“The Pentagon has sophisticated systems to ensure the safety of the building and its occupants,” Parnell said.
“Those systems have detected an air quality issue necessitating precautionary measures until we determine its significance.”
In a post on X, Arlington County fire and rescue also said its “units, including our Hazardous Materials Team, are currently operating at the Pentagon in support of PFPA’s Hazmat Team during a hazardous materials incident”.
In a statement provided to Al Jazeera, Parnell later said that “subsequent testing confirmed no hazard exists, and normal operations have resumed”.
It was not immediately clear what initiated the issue.
The 600,000-square-metre (6.46-million-square-foot) Pentagon is the world’s largest low-rise office building.
Nearly 30,000 military and civilian personnel work at the facility each day.
