At least three workers were seriously injured in an “electrical mishap” near the Medical Center Metro station Monday morning, according to a spokesman for Montgomery County Fire and Rescue.

Spokesman Pete Piringer said his department was alerted about a “possible electrical explosion” involving those working outside the Maryland Metro station at around 7:45 a.m.

All of the contractors have been removed from the electrical shaft, which Piringer described as a “fairly confined space.”

“Paramedics are treating and transporting several people, at least three fairly serious injuries as a result of electrical shock,” Piringer said in a video posted to social media.

Their injuries include serious electrical burns, Piringer said.

The station is located near the National Institutes of Health campus.

After initially stating that there would be no impact to service, Metro said just before 10:45 a.m. that trains were temporarily not running between Medical Center and Bethesda as authorities investigated a report of smoke.

Just before 12:30 p.m., Metro said trains were no longer single tracking. Transit officials haven’t said whether the closure was related to the electrical incident.
