Package Explodes At O'Hare, Injures Baggage Handler (VIDEO)

A package exploded at Chicago's O'Hare International Airport Tuesday, causing minor injuries to a baggage handler.

An FBI official told ABC Chicago that the incident appeared to be an accident. The explosion occurred after a large package fell to the ground after it was taken off an airplane near Terminal 1 Concourse C. The injuries to the arm and possibly the face of the baggage handler, which are not life-threatening, are the only injuries currently being reported as the area was evacuated after the incident.

The Chicago Fire Department told the Associated Press a battery that was being shipped in a container exploded. Fire officials said the baggage handler is an employee of United Airlines.

The incident is being labeled a Level 1 hazmat situation, meaning that a gas, liquid or solid has spilled, causing minimal-to-moderate risk to public health.

The owner of the bag has been identified and is currently being interviewed, though no criminal activity is suspected, CBS Chicago reports. Meanwhile, police, firefighters and members of the bomb and arson unit are continuing to investigate the incident.

The United employee has been hospitalized.
