Crews were called to the Giant located at 1250 Cocoa Ave around 5 a.m.
The fire started in the back of the store, where a staff member noticed flames coming from a cardboard baler-- a machine used to crush cardboard.
The flames spread from the baler to a nearby wall.
The employee called 911 and alarms went off in the store, activating the sprinkler system.
The building is a 54,000 square foot facility which required more ventilation than a smaller location so a large fan from Lebanon City was used.
The fire was contained to the baler and the back wall of the Giant.
Hershey fire department cleared the scene around 8 a.m.
No injuries were reported.
The fire remains under investigation.
The store is closed, it is unclear when it will reopen.
