D.C. Fire and EMS responded to reports of smoke in the Gelman Library Starbucks on 21st and H streets at about 6 a.m. Monday, a spokesman confirmed.

Oscar Mendez, a public information officer at D.C. Fire and EMS, said a transformer in the electrical room was “causing issues” and creating smoke. There were no injuries or transports from the scene and “everything was under control,” Mendez said.

About five fire trucks and an ambulance responded to the scene. The employees were evacuated.
