Dalian explosion (preliminary investigation results of accident cause announced)

The explosion in Dalian took place on the afternoon of July, 2065438 12 10, and the incident occurred in a chemical plant near the Bonded Zone in Jinzhou District, Dalian. After the explosion, the surrounding residents heard a huge explosion and saw flames and smoke as high as tens of meters. The accident caused many deaths and dozens of injuries, which also had a serious impact on the surrounding environment and ecology.

accident cause

After preliminary investigation, the accident was mainly caused by the leakage of raw materials from the chemical plant, and the high temperature weather led to the spontaneous combustion of raw materials, which eventually led to an explosion. Specifically, the main causes of the accident are as follows:

1. Leakage of raw materials

At the time of the accident, the raw materials of the chemical plant leaked, including flammable and explosive chemicals such as propylene, styrene and ethylene. Because the leaked raw materials were not treated in time, the raw materials spontaneously ignited at high temperature, which eventually led to an explosion.

2. Hot weather

At the time of the accident, the weather in Dalian was hot and the temperature reached above 35℃. High temperature weather and leakage of raw materials in chemical plants make raw materials more prone to spontaneous combustion, which leads to explosion.

3. Safety management is not in place

It is understood that there are some problems in the safety management of chemical plants, including the untimely treatment of leaked raw materials and incomplete fire-fighting facilities. All these problems led to the accident.

Accident influence

The explosion in Dalian had a serious impact on the surrounding environment and ecology. A large number of harmful gases and wastewater produced by the explosion polluted the surrounding air and water quality, and also had a certain impact on local crops and aquatic organisms. In addition, the accident also had a certain impact on the life and work of local residents, including road traffic and water and electricity supply.

Accident lesson

The explosion in Dalian gave us a wake-up call, reminding us to pay attention to chemical safety issues, strengthen safety management and prevent chemical accidents. Specifically, it can be improved from the following aspects:

1. Safety management

Chemical plants should establish a perfect safety management system, strengthen the storage and management of raw materials, deal with leaked raw materials in time, and ensure the safety of chemical production process.

2. Fire fighting facilities

The chemical plant should be equipped with complete fire-fighting facilities, including fire-fighting equipment, fire exits, fire water sources, etc. , to ensure that the fire or explosion can be controlled in time.

3. Environmental protection

Chemical plants should strengthen the treatment of wastewater and waste gas to ensure no pollution to the surrounding environment and ecology.
