PALMYRA, N.J. (CBS/AP) – Authorities in Palmyra, N.J., say a contractor cleaning an empty fuel tank at a gas station on Route 73 near the Tacony-Palmyra Bridge has been severely burned.

The incident happened just after 12:30 p.m. at the Gulf gas station, located in the 1200 block of Route 73 in Palmyra.

Police say the contractor for Gulf Oil somehow created a spark which apparently caused an explosion. Police say residual fuel in the tank also caught fire.

Chopper 3 HD was over the scene as firefighters filled the tank with foam.

The Burlington County Bridge Commission Police Department urged drivers to use Temple of Market Streets in Palmyra to access the bridge during the closure of Route 73 at the FC Kerbeck jug-handle.

Officials confirmed that Route 73 was reopened at 2:05 p.m.

The injured contractor was taken to Cooper University Hospital in Camden. His identity was not immediately released.
