| Place |
Mihara City, Hiroshima Prefecture. |
| Location |
a construction site of the purifying plant |
| Overview |
In a construction of the purifying plant, the reinforced steel floor of the hydrograph room was longer than the design length. Therefore, after assembling the reinforced steel, the worker cut the end of the reinforced steel with a hand style reinforced steel cutter, and the offcut was sprung, and it hit his left eye. |
| Incident |
On that day, when the worker did the assembly work with the reinforced steel floor of the hydrograph room, he noticed that part of the bottom reinforced steel was about 3 - 5cm longer than that of the design. He consulted with the foreman about that, and the foreman directed him to cut off the reinforced steel after assembling reinforced steel. So he decided that he cut the extra reinforced steel edge with the hand style reinforced steel cutter. He cut off the reinforced steel with the hand style cutter at the length of the design, but then the offcut was sprung and it injured his left eye by it. |
| Sequence |
* The cutting work of reinforced steel started from 2 p.m.. But because of a bad cutter, he changed the cutter after the rest at 3 p.m., and he proceeded with the work.
* At about 4:50 p.m., just before the work ended, the offcut was sprung and it injured his left eye. |
| Cause |
* Since the worker noticed the difference between the top and the bottom reinforced steel in the middle of the work, he consulted with the foreman and staff in charge, and he resulted in cutting it with the hand style reinforced steel cutter after assembling the reinforced steel.
* The worker held the reinforced steel with his hand at the beginning of the work, but he didn't hold it when the accident happened.
* The worker didn't estimate that the offcut of the reinforced steel was sprung and that it hit his eye.
* The offcut was sprung higher than expected since the reinforced steel was small.
* The meeting of the detailed procedure of the cutting work was not carried out.
* The cutting work was thoughtlessly carried out. |
| Countermeasures |
* Before cutting work, the cutting place was held by a thick cloth, a net of a small mesh, or things to prevent a offcut from scattering.
* Face protector should be used.
* The dimension of reinforced steel is checked during the temporary assembly of reinforced steel.
* Hand style cutter is not used with the thing which is expected to be sprung during cutting. |
| Knowledge Comment |
* If the offcut is not held, it is sprung.
* The direction of springing can't be estimated.
* Even if a case is safe, it is not known whether the next case is safe.
* One should defend oneself !
* Habit is taboo ! |
| Account of Concerned Parties |
* The worker intended to finish the cutting work by the work end ( 5:00 p.m.). |
