BOSTON (MyFoxBoston.com) -- Firefighters are battling a blaze on Beacon Street that began Wednesday afternoon. 18 people have been taken to the hospital, Boston EMS reports.
Firefighters responded to 298 Beacon St. at 2:43 p.m. and have struck a ninth alarm on the fire, which is the highest number of alarms the system reaches. It took just 30 minutes for officers to hit nine alarms.
As of 4 p.m., the fire was still raging inside the building. All firefighters were fighting the fire from outside of the building. Wind gusts in Boston were reaching 50 miles per hours Wednesday afternoon.
The fire began in the basement of the four-story brownstone apartment building, and escalated all the way through the roof. Thick smoke could be seen coming from the building throughout Boston.
At 4 p.m., Boston EMS released information on where 10 of the injured were sent, though officials did not specify whether or not those were all firefighters. Six people were taken to Brigham & Women's hospital, two were taken to Mass. General Hospital, and two were taken to Tufts Medical Center.
Earlier, Boston Fire Department spokesman Steve MacDonald said three firefighters were transported to Brigham & Women's hospital, one with serious injuries and two with non-life threatening injuries. Three were treated on the scene.
Though people were inside the building at the time, they were able to leave out a back fire escape and currently there are no reports of people missing, MacDonald said.
One woman who lived in the building and was home when the fire started said, "I was in the apartment and I heard shouting and yelling and the people that were in the building next door were going down the fire escape and two seconds later, the firemen were there. So I looked out the window and I saw the smoke and I was like I gotta get out of here so I grabbed my laptops and this box and I left. And then, as I was leaving the smoke was coming into the building, into the apartment and the firemen were there yelling, 'Everybody get out.'"
She was on the second floor of the building when the fire started. Once out of the building, she saw smoke and people throwing suitcases out of the windows.
Another man, who was on the first floor of the building when the fire started, said, "I saw the smoke start coming up, I saw people climbing down from the top floor. The fire and police were there almost right away. There was a lot of smoke, there was a small explosion at the beginning of the fire, and it just got worse and worse."
Fire officials are conducting an accountability check to make sure all firefighters are accounted for. Between 20 and 30 trucks responded, and each carries approximately four people, MacDonald said.
Suffolk County prosecutors are responding to scene of the fire, according to the Suffolk County District Attorney's office. Boston Mayor Marty Walsh is also at the scene, as is the Boston Red Cross.
Boston Police closed Beacon Street from Arlington Street past the intersection of Fairfield Street. Storrow Drive eastbound has been closed at the Fenway/Kenmore exit. Commuters are being allowed to turn right from Commonwealth Avenue onto Berkeley Street to Storrow Drive eastbound. Storrow Drive westbound has been closed at Leverett Circle.
According to the city assessor's office, the building is worth $1.6 million.
