The reporter learned from the Shanxi Jincheng Government Information Office that the search and rescue work at the Yanjiu tunnel accident site on Jinji Expressway in Jincheng City, Shanxi Province, was completed on March 1. The tunnel section of the Yanji tunnel of Jinji Expressway has been resumed to traffic, and the accident has entered the aftermath. And investigation stage. An ordinary traffic collision accident resulted in the death of 13 people as a result of a dangerous car driver's unauthorized handling. More than 40 vehicles and more than 1,500 tons of coal in the tunnel burned, causing liquid natural-gas vehicles to explode. The fire burned for 73 hours before being extinguished. . The cause of the accident is under investigation, but it has initially exposed multiple potential safety hazards.

Session One: Driver's Infringement Causes Fire

At 14:50 on March 1st, Li Jianyun, driver of Fuanda Logistics Co., Ltd., Jincheng, Shanxi Province, drove heavy-duty tank trucks (with nuclear loading of 30.6 tons and actual loading of 29 tons of methanol) and traveled from north to south to 1060 kilometers of the Erguang Expressway. In the section of Yanhou tunnel at 900 meters, the light entering the tunnel suddenly dimmed, and vehicles in front of the tunnel were not waiting in time to wait for traffic. As a result, a heavy tanker truck driven by Tang Tiancai, a transportation company in front of Mengzhou City in Henan Province, was collided with a collision of 10 meters into the tunnel. 32 tons of nuclear load, actual load of 29.6 tons of methanol). At that time, the accident did not cause casualties.

After the vehicle collided, Li Jianyun and Tang Tiancai got off and checked the situation and found that the two cars were stuck together and there was a methanol leak. After private consultation, the vehicle driver Tang Tiancai, who was in front of the vehicle, drove the vehicle to move forward. After the two cars were separated, they got out of the car and checked the situation to find that the leaked methanol was burning. A total of 4 drivers and escorts on the two vehicles abandoned the vehicle and fled the scene. At present, these 4 people have been controlled by the police.

Session 2: Transport companies only collect money without management

The state has strict regulations on the transportation management of hazardous chemicals. Both drivers and escorts must undergo professional training. According to investigations by the Traffic Police Corps of the Public Security Department of Shanxi Province, the drivers and escorts on the two vehicles involved in the collision accident hold business qualification certificates. However, the characteristics of the goods being transported, the regulations for safe transportation, and the emergency treatment methods for accidents occurred. No knowledge of basic knowledge is known, only that the goods being pulled are flammable.

According to Tang Tiancai, the car he drove was personally owned and affiliated with the Mengzhou City Automobile Transportation Co., Ltd. of Henan Province. The transportation company only collected money and did not manage it. The usual safety education and management were in the form of education. Sign it. Li Jianyun said that just one month after he had been on the job, the company did not have a special safety inspector. The safety inspections of the vehicles that he usually traveled depended on himself.

Session 3: Emergency escape passage closed

According to on-site rescue workers, there was no exhaust facility in the 800-meter-long Yanhou tunnel. After the accident, the smoke in the tunnel rolled, and rescue workers wearing gas masks and oxygen tanks could not wait for 20 minutes.

The smoke alarm failed and did not function as an alarm. Some people in the vehicle did not flee in time. The emergency escape channel in the middle of the tunnel was closed and the escape instruction was not obvious. After the fire accident, the scene was in confusion and personnel could only exit from the tunnel. Escaped, the middle man did not have time to flee.

What's more regrettable is that fire-fighting taps do not produce water. Fire-fighting vehicles can only pull water from the high-speed road to extinguish the fire and cool down, delaying the extinguishing time. In 1 hour and 40 minutes after the accident, a large vehicle carrying liquefied natural gas exploded. Half of the car was blown into the tunnel by 50 meters.

The reporter’s investigation revealed that a coal char management station is located 5 km south of Yanhou tunnel’s north exit. On February 28th, due to heavy snowfall in the Jincheng area, traffic control was imposed on highways in the Jincheng area. The Jinji expressway was closed at 17:40 on the same day due to lack of access conditions. At 7:10 on March 1st, the Jinji Expressway resumed traffic, causing the coal transportation vehicles to enter the area. Due to the slow passage of the coal coke management station, the vehicles in the road section of the accident were congested. There were 33 coal trains waiting in the tunnel. Finally, the coal on the vehicle was ignited and the consequences of the accident were aggravated.
