Boston firefighters responded at 5:40 p.m. to 28 Grantley St., off Hyde Park Ave., for what turned into a five-alarm blaze in a warehouse at Hyde Park Masonry and Supplies.
At times the smoke was so thick firefighters with hoses at the top of one of three ladders were not visible from the street. Police evacuated nearby homes on Grantley Street and ordered onlookers away from the front of the fire scene on Hyde Park Avenue. Thick smoke filled the streets a couple blocks south of the warehouse.
Firefighters fought the blaze entirely from the outside, in part due to the presence of tanks of chemicals inside the warehouse.
Two firefighters were injured, one seriously enough to be taken to a local hospital, although his injuries are not life threatening, BFD says.
Fire Commissioner Joe Finn arrived and took control of the fire operations.
Firefighters are continuing to pour water on the building (photo by BFD) and expect to remain on scene overnight.
