Chief Rick Myers of the Ellwood City Fire Department said the department was alerted around 11 a.m. to an explosion at the Ellwood City Forge in the downtown area of Ellwood City.

Upon arrival, it was discovered that two people were injured. One with severe burns was flown to a Pittsburgh-area hospital, while the second victim with less severe injuries was taken by ground to a local hospital.
