Emergency crews remained on scene late into the evening Monday after a major gas leak was reported at the QTS data center just outside the City of Manassas.

Prince William County Fire and Rescue was dispatched to 9540 Godwin Drive at 2:10 p.m. for reports of a gas leak. As of 9 p.m., units were still actively working the scene.

Spokesman Matt Smolsky said the leak involved an 8-inch gas line, which significantly prolonged containment efforts.

“Takes time to isolate and secure leaks of that size,” Smolsky said. “Units are protecting the scene regarding escaping vapors and scene safety.”

There were no immediate reports of injuries or evacuations, but emergency personnel continued to monitor the area for potential hazards.

The QTS data center sits near Godwin Drive, across from Mircon Technologies,  and is part of the region’s growing technology infrastructure.
