7 FDNY firefighters transported to hospital after responding to 3-alarm fire in the Bronx

FDNY crew members responded to a three-alarm fire in the Bronx Wednesday.
More than 100 firefighters were seen at  551 East 179th St. They say the fire was in the cockloft of the location. 
Seven firefighters were transported to the hospital. No civilians were injured. 
Officials tell News 12 that FDNY members had to be pulled out of the building due to fears the building would collapse. 
Fire officials say the flames blew out out of the building and over to a Con Edison power plant next store. They say the building was not impacted by the flames. 
Firefighters were concerned that gas tanks inside would cause a larger explosion. 
Fire officials say work was being done in the building before the fire broke out.
