On January 13, 2006, at 6:00 PM, Wang ** (a 38-year-old female quality inspector at Jiuquan Iron & Steel (Group) Co., Ltd.) was at the rolling mill factory when she met with sculptor Zhao ** to inspect the ladle of the casting roll. After the molten iron returned to the slag, it became severe, and the impact on the roll's quality was reported. Upon inspection at the casting site, workers Xue **, Wang **, Fu **, and security personnel ** were in the process of slagging a hot metal ladle. Wang ** stood to the east of the pouring cart, observing whether any slag remained in the ladle.
After the slag removal (approximately two minutes into the process), Xue **, who had already started the pouring operation, called out to those nearby: “Everyone move to the side and pour it.†At that time, Pay ** was moving to the safety channel on the south side of the area, while Wang ** was standing about two meters to the northeast of the pouring truck. Suddenly, Wang ** turned around and noticed Wang ** standing on the pouring pipe that had been temporarily placed on the south side of the pouring pit. The pit had eight pouring pipes arranged side by side in an east-west direction. Wang ** was positioned from west to east, standing on one of these pipes. The pipe had an inner diameter of 280mm, a height of 1.4m, and square flanges measuring 450x450mm at both ends. The upper flange of the casting pipe was 775mm above the height of the safety wall surrounding the pouring pit.
At 6:15 PM, the pouring of molten iron was completed, taking approximately 30 seconds. Xue X, An, and Wang X pushed the pouring cart along the track, and glass slag scattered from the south side of the centrifuge. At this moment, Zhang **, who had just finished filling out the record before the centrifuge console, suddenly heard a scream and then a loud noise. He looked up and saw that Wang ** had vanished. Before the pouring began, Zhang ** had seen Wang ** standing on the safety wall of the pouring pit, holding the pouring pipe. He ran over and asked, “Where is King **?†Then he went to the west of the pouring pit and looked down, finding Wang’s head facing south on the cold-type iron sheet inside the pit. The pouring pit was 6.5 meters deep, and the cold-type structure was 3.02 meters high, extending 3.5 meters from the edge of the pit. Zhang shouted, “Hurry, someone fell down!†Others rushed to save the person, and eventually, King **, **, and Xue ** descended into the pit, lifted King ** from the cold-type structure, and used a crane to pull the bucket out of the pit.
At 6:30 PM, Wang Jianping was taken to Jiugang Hospital for emergency treatment but died at 12:30 AM on January 14, 2006.
**Accident Category**: Falling from Height
**Direct Economic Loss**: 130,000 RMB
**Direct Cause**: Wang ** stood on a high, narrow pouring pipe, which led to a careless fall.
**Indirect Causes**:
1. The protective railings near the casting pit were not properly set up, creating a hazardous environment without clear warning signs.
2. Wang **, Zhang **, and others failed to stop the dangerous behavior of standing on the pouring pipe during the operation.
3. Safety education was lacking, and there was insufficient supervision on the work site.
**Nature of the Accident**: A liability accident.
**Responsibility and Handling**:
- Wang ** was directly responsible for her actions, but as she died in the incident, no further action was taken.
- Zou **, the director of the rolling mill, was held accountable for failing to manage potential hazards.
- Liu **, the deputy manager, was given a formal warning for insufficient oversight.
- Other officials were also subject to disciplinary actions based on company regulations.
- The main person in charge of the company was recommended to face administrative penalties.
**Preventive Measures**:
1. The company must strengthen safety awareness and conduct reflection activities to prevent future incidents.
2. Standing on the safety wall of casting pits is strictly prohibited.
3. Three movable cover plates were installed to close the casting pits.
4. Safety warnings should be improved in all hazardous areas.
