Two workers rescued from chocolate tank

Two people were rescued after they fell into a partially filled chocolate tank while doing maintenance work at a candy factory in Pennsylvania.

The incident at the Mars Wrigley plant in Elizabethtown occurred shortly before 2 p.m. Thursday. The two people work for an outside contracting firm, officials said, and it's not clear how they fell into the tank.

Emergency responders were able to free the pair by cutting a hole in the bottom of the tank, officials said. They were taken to hospitals to be evaluated. Their names and further details on their conditions were not disclosed.

The federal Occupational Safety and Health Administration are investigating the incident.
