At least three people have been injured after a large commercial building explosion Wednesday afternoon in Logan Township, N.J., and Gloucester County Emergency Management asked people nearby to shelter in place.

Residents and businesses within a two-mile radius of Heron Drive and High Hill Road were asked to shelter in place until further notice, the county emergency management said in a post on social media.

The explosion occurred around 2:35 p.m. and firefighters who were first on the scene at 617 Heron Drive said at least two people had been severely burned, and the building had collapsed with a ruptured propane tank still burning.

Cooper University Hospital received three patients, said Cooper spokesperson Wendy A. Marano. Two of the patients were seriously injured.

Residents across the area said the explosion shook their houses.
