An employee was feeding foil inner lid seals into the shuttle stacker on a pint filler machine when some of the seals fell onto the conveyor. The employee attempted to grab a stack of the seals from the conveyor. Her right hand was then caught and pulled into the machine, making contact with the heat seals. She sustained third degree burns on her right palm and forearm and multiple lacerations to her hand and arm, requiring hospitalization. The machine was running at the time of the incident.
