As many as 11 workers are being treated for exposure after an acid release at the Sunoco refinery in South Philadelphia. The hydrofluoric acid release happened around 10:30 this morning. Sunoco emergency personnel responded to the scene and were able to stop the vapor release.

Four hazmat crews were dispatched to 3000 Penrose Avenue to treat workers who had been exposed to vapors.

A total of 10 people have been transported to local hospitals - 7 to Methodist Hospital and 3 to the Hospital of the University of Pennsylvania. All are in stable condition.

Authorities are still trying to determine what caused the release.

Sunoco released a statement saying the incident was contained to the refinery and that there was no impact outside of the plant.

Hydrofluoric acid is a hazardous liquid and vapor which can cause severe burns, which may not be immediately painful or visible. It may also be fatal if swallowed or inhaled.
