A fire erupted in an empty operating room at St. Vincent’s Medical Center on Saturday afternoon before being quickly extinguished by automatic sprinklers, officials said. 

Firefighters were dispatched around 2 p.m. to the hospital at 2800 Main St. in response to a fire alarm, according to Tiadora Josef, Bridgeport’s director of public information.

Josef said the responding crews arrived to find the aftermath of a small fire in an operating room that has been extinguished by an automatic sprinkler. She said the crews confirmed the fire was out and has not spread.

Building officials then shut the sprinkler head off and maintenance crews began cleaning up the residual water, Josef said.

Josef said no injuries were reported and the building was not evacuated. She said the operating room was not in use at the time of the fire and the fire marshal’s office is investigating the cause of the blaze.
