alert!Such accidents have entered multiple periods!

Summer flood season

High temperature, lightning, heavy rain, typhoon, etc.

Extreme weather increases, and various risks are superimposed

Dangerous chemical accident enters a period of prone to multiple occurrences

Case number one

At 4:28 am on June 18, 2022, a fire broke out in the ethylene glycol device area of ​​the Ministry of Petrochemical and Chemical Engineering. The relevant municipal and district departments immediately launched an emergency plan and organized rescue forces to rush to the scene for rescue. At present, the accident has caused a slight bruises for a employee in Shanghai Petrochemical, and a third -party transport vehicle driver's death is further investigating. At 16:30 on the 19th, after 36 hours of coordinated disposal of multiple rescue forces, the fire was completely extinguished, related aftermathing was promoted in an orderly manner, and the cause of the accident was under investigation.

Case 2

At 18:50 on June 16, 2022, the sewage treatment workshop in a chemical enterprise in Lanzhou New District, Lanzhou New District, Gansu Province exploded; as of 20:00 on the 17th, six lost people confirmed that the unfortunate death was killed. The remaining seven were treated in the First People's Hospital of the New District, and the signs of life were stable. A total of 420 fire rescue workers, 73 fire trucks, and 6 search and rescue dog disposal accidents were mobilized at the accident site.

Case II

At 12:45 on June 8, 2022, the leakage of the pump of a canal pump in Maoming Petrochemical Branch caused an explosion. The main combustion was ethylene. The fire caused 1 person to be injured and two people lost contact. It took 90 hours from fire to extinguishing. After receiving the report, the Guangdong Provincial Fire Rescue Corps launched an emergency response of cross -regional chemical accidents as soon as possible, and 7 fire rescue detachments of Maoming, Zhanjiang, Yangjiang, Jiangmen, Foshan, Guangzhou, and mobile detachments were mobilized. Firefire rescue workers participate in the accident handling of the accident.

Case 4

On May 31, 2022, the first chemical plant in Ruicheng County, Yuncheng, Shanxi, exploded during the suspension of production and maintenance equipment, causing three people to be injured and injured.

What is the hazardous chemical ginseng?

Many people have questions about this

Let's come to popular science today

Science

Know the dangerous products

The hazardous chemical chemicals are highly toxic chemicals and other chemicals that have toxic, corrosion, explosion, combustion, and burning, and are harmful to the human body, facilities, and the environment. Harm of hazardous chemical accidents

In the outside world (such as heating, friction, impact, etc.), some hazardous chemicals can cause severe chemical reactions, and instantly generate a large amount of gas and heat, which increases the surrounding pressure sharply and exploded. There are three main hazards of hazardous chemicals: burning hazards, health hazards, and environmental hazards.

How to save yourself

Unlike ordinary explosions and fires, the hazards of the explosion of hazardous chemicals are more likely to cause serial explosion and harmful gases. So, how should ordinary people save themselves in such emergencies?

01

Most of the toxic gases are heavier than air, and they will gather at low terrain. After the explosion of hazardous chemicals, keep in mind the first principle -quickly evacuate in the direction of the upper wind.

02

If the explosion position is at the upper air outlet, most people will subconsciously run in the direction of the explosion point, but if the explosive gas is poisonous, it will always be on the forward line of poisonous gas. The correct way is to bypass the explosion point, and then evacuate up the upper vent.

03

Keep exports smoothly, have food and water drinking reserves, wait for the notification to go to the evacuation site, and avoid blind action.

The safety of hazardous chemicals is the top priority of safe production. So what are the specific requirements for the safety management of dangerous chemical storage warehouses?

Standard storage range

The special warehouse of hazardous chemicals shall meet the requirements of national standards and industry standards. According to the characteristics of hazardous chemicals, it should be stored in partition, classification, and database, and clearly storage varieties, storage areas, and storage quantity. We must not change the design and use of the hazardous chemical warehouse without authorization. The taboo dangerous chemicals must not be mixed. The stacking distance, lighting, wall, column distance, and top spacing of the items in the warehouse should meet the "five -distance" requirements.

Standard safety measures

The storage venue of hazardous chemicals should be equipped with lightning protection, anti -static, waterproof, ventilation, explosion -proof, monitoring alarm and other facilities and equipment according to the characteristics of storage.

Explosion -proof facilities

The electrical equipment, transmission and distribution lines, and loading and unloading machinery tools in the warehouse of flammable and explosive chemicals should adopt the explosion -proof type that meets the requirements. When the electrical lines use the metal tube wiring, the thread rotation connection such as the metal tube and the wiring box should be firm and firm, and the places where the wiring is more difficult to curvature can be connected to explosion -proof oscillating hose.

Lightning protection and electrostatic facilities

At the outside of the entrance of the warehouse of flammable and explosive chemistry, the human static release device shall be set up. The warehouse rowing fan and metal shelves should be equipped with ground electrical grounding devices. Lightning protection and anti -static devices should be complete and regularly detected.

Monitoring alarm facilities

The places with flammable gas and toxic gases in the library shall be set up with flammable gas and toxic gas alarm devices. The installation height shall meet the requirements of combustible gas (toxic gases) and air. The gas alarm device shall commission qualified institutions to test regularly.

Ventilation facility

The flammable liquid and flammable gas warehouse should be set up with emergency compulsory exhaust systems, and explosion -proof exhaust fans should be installed. The exhaust pipe should be used to use metal pipes and should be directly directed to outdoor safety locations.

Anti -overflow facility

Class A, B, and C liquid warehouse should be set up to prevent liquid flowing facilities, and measures to prevent water immersion should be taken when storing items for wet and burning explosions.

Fire facilities

The hazardous chemical warehouse shall be equipped with fire extinguishing equipment that meets the standard requirements. It should not cover the fire hydrant, automatic spraying system, and smoke discharge port.

Dangerous chemical accident is fierce than tiger

Strictly store hazardous chemicals in accordance with standards

Normal inspections, discover hidden problems in problems

Solved in time to ensure safety!
