"Once our firefighters arrived, they did make an aggressive interior attack," Fire Chief Brian O'Neill said. "We had one person that was pinned. We were able to get them out, rescue them, as well as assist the others in evacuation."

O’Neill added that officials are monitoring the air and that there is no sign of "any type of chemical problems in the air."

Aerial images show smoke rising from the damaged building, which had a structural collapse. The inside of the building was also visible in a gaping hole caused by the explosion.
