2-alarm fire breaks out at Rockville apartment building

ROCKVILLE, Md. - Fire crews are investigating a 2-alarm fire that broke out an apartment building in Rockville, Maryland on Thursday afternoon.

According to Montgomery County Fire and Rescue Service (MCFRS) officials, crews responded around around 12:30 p.m. Thursday to reports of a fire at the Grosvenor House Apartments located at 10101 Grosvenor Place.

Once there, crews noticed heavy smoke showing from the upper levels of the building. About 85 to 90 firefighters responded to the scene to help with the fire.

Fire officials confirm an electrical fire broke out on the ninth and tenth floors of the building. They say the fire originated in an electric busway where 2 sections of the busway join. They believe the fire was most likely caused by a significant arc which blew through the metal housing of the busway.

The flames were brought under control thanks to the building's sprinkler system.

Officials report there is significant fire, smoke, and water damage to the building. They also say the north tower of the building remains without power, but the south tower has had power restored. People who live in the south tower can now re-occupy the building.

According to officials, several dozen residents who live on the eighth, ninth, and tenth floors of the building have been displaced. Officials are coordinating with the Red Cross and Montgomery County Department of Health and Human Services to help the people who have been displaced.

No injuries have been reported at this time. Fire officials say the building, which houses nearly 1000 residents, was evacuated after the fire.
