The employee of Kusu Plant (sent to Saga Plant by request) was exchanging a mold to implement a countermeasure for weld in molding.
He detached the spacer block (about 8kg) from the mold during the disassembly of the mold and carried it with both hands to another area in the mold workspace.
At that time, he stumbled over a rubber mat and fell down. Then, he hit his left mid finger on a nearby crosstie and was injured.
