Read： 812 Time：19months ago Source：Transform the World with Simplicity

Dibasic acid ester (DBE) is widely used in the field of chemical production raw materials, but its safety and storage and transportation regulations are very important to ensure production safety and personnel health. This article will detail the safety, storage and transportation specifications of DBE to ensure safety and reliability during production and use.

1. safety of DBE

1. Toxicity: DBE is a low-toxic substance, but long-term exposure or inhalation of high concentrations of DBE vapor may cause harm to the human body, such as irritation to the eyes, skin and respiratory system. Therefore, when operating DBE, wear protective glasses, gloves and other personal protective equipment, and ensure that the workplace is well ventilated.
2. Flammability: DBE is flammable and can cause combustion and explosion when exposed to open flame, high heat or oxidant. Therefore, the storage and transportation process should be away from the fire source, heat source, prohibit mixing with oxidant and other substances.
3. Stability: Under the specified storage and transportation conditions, DBE is stable in nature and is not prone to chemical reactions such as decomposition and polymerization. However, under the conditions of high temperature and light, DBE may decompose to produce harmful gases, so it should be avoided to store it for a long time under high temperature and light environment.

2. DBE storage specification

1. Storage facilities: DBE should be stored in a cool, ventilated and dry special warehouse, away from fire and heat sources. The warehouse floor shall be anti-skid and anti-static, and equipped with fire fighting equipment and leakage emergency treatment equipment.
2. Storage container: DBE should be stored in a special container, and the container should be well sealed to prevent leakage. The container shall be marked with the name of the substance, its danger and safety precautions.
3. Storage limit: According to the actual situation of the enterprise and legal requirements, the storage limit of DBE should be reasonably controlled to avoid the security risk caused by excessive storage.

3. DBE transportation specifications

1. Transportation vehicles: Use special transportation vehicles for DBE transportation. The vehicles should have good sealing performance to prevent leakage. At the same time, the vehicle should be equipped with fire fighting equipment and leakage emergency treatment equipment.
2. Transportation personnel: transportation personnel should have relevant qualifications and operation skills, understand the nature of DBE and safe operation procedures. In the process of transportation, personal protective equipment should be worn to ensure their own safety.
3. Transportation route: Choose a reasonable transportation route to avoid passing through sensitive areas such as densely populated areas and water source protection areas. At the same time, traffic rules should be observed to ensure transportation safety.

4. emergency treatment measures

1. Leakage treatment: in case of DBE leakage, the emergency plan shall be started immediately, effective measures shall be taken to control the leakage, and the leakage shall be safely treated. At the same time, leakage should be prevented from entering environmentally sensitive areas such as sewers and drains.
2. Poisoning treatment: if poisoning symptoms occur after contact with DBE, the poisoned person should be moved to a well-ventilated place immediately, and necessary first aid and protective measures should be given. At the same time, medical institutions should be contacted in time for treatment.

In short, the production and use of dibasic acid esters (DBE) must strictly comply with safety and storage and transportation regulations to ensure production safety and personnel health. By strengthening the management and operation standards, the security risks brought by DBE can be reduced, and a strong guarantee for the stable development of enterprises can be provided.
