Two people were seriously injured in an propane tank explosion at a gas station in North Andover, Massachusetts on Monday afternoon.
The explosion, which involved a white camper, occurred shortly before 4 p.m. at a Mobil gas station on Osgood Street.
The victims — an employee and a customer — were taken to local hospitals via medical helicopter with burn injuries. Their conditions are not known at this time.
Fire officials said there were flames showing when they arrived. They said it was difficult for them to turn off the gas from the propane tank right away, but they eventually were able to do so.
Deputy Fire Chief Graham Rowe says a propane explosion like this, especially at a gas station, is rare.
Officials added that the hot weather made it harder on the fire crews, but no firefighters needed any treatment for heat exhaustion.
The cause of the explosion remains under investigation. No further information was immediately available.
