How to store hazardous chemicals safely in summer?

On June 17, 2022, in Shanghai, China, the explosion of Jinshan Petrochemical Company aroused our great attention. Every summer, there are many explosions in chemical plants. In the hot weather in summer, flammable, explosive, toxic, corrosive and volatile chemicals can easily cause safety hazards or accidents if they are not managed properly in hot weather. How to deal with the safety management of hazardous chemicals in summer and prevent accidents? SYSBEL provides you with professional and complete solutions for the safety management of hazardous chemicals.

01 Influence of high temperature in summer on hazardous chemicals

Thermal expansion and contraction are general physical phenomena of objects. The expansion coefficient of flammable liquids is generally relatively large. When stored in a closed container, the volume is easy to expand after being heated. At the same time, the vapor pressure increases, which increases the internal pressure of the container. If it exceeds the pressure that the container can bear, it will cause the container to malfunction. even burst. In the high temperature season, the "drum barrel" phenomenon of iron drums containing flammable liquids and the bursting of glass containers are caused by thermal expansion. If the container is open, the liquid will expand beyond its capacity and overflow, resulting in the phenomenon of running, running, dripping and leaking.

02 Precautions for preventing hazardous chemical accidents in summer

1. Have a qualified warehouse for hazardous chemicals

Hazardous chemical warehouses should use non-thermal refractory materials as insulation layers on the roof and walls, and the eaves should be properly lengthened to prevent sunlight from entering the warehouse; for laboratories without Class A warehouses, waste liquid or waste can be temporarily stored in SYSBEL In the Hazardous Chemicals Warehouse, Sisbell Hazardous Chemicals Warehouse can meet your needs, 18 systems are optional, all the security guarantees you can think of are our standard configuration, intelligent IoT cloud management platform, automatic real-time monitoring , Without the need to build an expensive Class A warehouse, it can also be compliant & safe to temporarily store hazardous chemical waste liquid and solid waste.

2. Hazardous chemicals should be reasonably classified and stored

Dangerous chemicals are generally divided into explosive articles, combustible articles in contact with water, spontaneous combustible articles, flammable solids, flammable and combustion-supporting gases, corrosive articles, oxidants, etc. These items should be classified, stored in separate warehouses, divided into parts, and stored in separate shelves. It is strictly forbidden to mix items that conflict with each other, have different fire fighting methods, and are likely to cause spontaneous combustion.

3. Gas Safe Storage

Improper storage of high-temperature gas cylinders in summer is quite dangerous. The expansion coefficient of flammable liquids is generally large. When stored in a closed container, the volume expands after being heated, and the vapor pressure increases at the same time, which increases the internal pressure of the container. If it exceeds the capacity of the container Under pressure, the container will fail or even rupture. Should be stored in a safe storage container.

The SYSBEL explosion-proof gas cylinder cabinet has been certified by the national authority, and has reached the explosion-proof standard of the whole cabinet (certificate number: GYB21.3799X) and obtained the highest level of EX d mb IIC T6 Gb approval. The gas cylinder cabinet uses a double-layer steel structure cabinet to meet the safe storage of general gases and special gases in each unit. The standard automatic blocking fire source device makes the storage of gas cylinders more secure.

03 Intelligent and safe storage monitoring from time to time

The temperature in summer is hot, and it is most important to keep the temperature inside the cabinet suitable. However, we cannot measure the temperature of each cabinet, let alone place it in an air-conditioned space. SYSBEL intelligent safety storage cabinet can help you solve the above problems. You can remotely manage the entire building, the entire park, and even smart security devices across the country with one click on the cloud, and view the security status of each security point in real time, allowing you to control security data at the first time, and manage all security storage cabinets with one click .

Intelligent security informationization

04 Take precautionary measures to prevent leakage

In summer production, the product is volatile, and the container should be regularly checked for corrosion, aging and leakage. Once the material leaks, it will not only cause environmental protection accidents and material loss, but also most likely cause personnel poisoning. Disposal of spilled product.

05 Take precautions

Hazardous chemical warehouses are generally located at the edge of the unit or city, keeping a certain distance from other surrounding buildings. In this way, an open area is formed around the warehouse, which is prone to lightning strikes. Therefore, the warehouse should install lightning protection devices to prevent fire accidents caused by lightning strikes.

06 Strengthen the management of on-duty personnel

Personnel who manage hazardous chemical warehouses must undergo fire safety training, pass the examination, and hold certificates. Warehouse management personnel should regularly inspect the warehouse, find problems and solve them in time to ensure safety.
