Read： 735 Time：17months ago Source：Transform the World with Simplicity

Tetrahydrofuran (THF) is a common organic solvent, which is widely used in the field of chemical production raw materials. Due to its flammable, explosive and toxic properties, it is necessary to strictly comply with relevant safety regulations during storage and transportation.

1. the physicochemical properties of tetrahydrofuran

Tetrahydrofuran is a colorless transparent liquid with an odor similar to ether. It is insoluble in water but miscible with many organic solvents. Tetrahydrofuran has a low flash point and is easy to burn, so it is easy to cause fire or explosion in the presence of high temperature, open flame or oxidant.

2. the toxicity of tetrahydrofuran

tetrahydrofuran has a certain toxicity to the human body, long-term exposure or inhalation of high concentrations of tetrahydrofuran vapor may lead to poisoning. Poisoning symptoms include dizziness, headache, nausea, vomiting, coma and so on. Therefore, in the storage and transportation of tetrahydrofuran, it is necessary to take effective measures to ensure the safety of personnel.

3. tetrahydrofuran storage specification

1. The storage place should choose a cool, ventilated and dry place, away from open flame, heat source and oxidant.
2. The storage container shall be a special container with good sealing performance to avoid leakage and volatilization.
3. The storage area shall be provided with obvious safety signs and warning signs, and smoking and open fire shall be prohibited.
4. Check and maintain the storage container regularly to ensure that it is intact.

4. tetrahydrofuran transport specification

1. transport vehicles should comply with the relevant standards, with fire, explosion, anti-static and other safety facilities.
2. During transportation, it should be kept stable to avoid violent vibration and collision.
3. Transport personnel should be professionally trained to understand the nature of tetrahydrofuran and safe operating procedures.
4. During transportation, relevant laws, regulations and regulations shall be observed to ensure safe transportation.

5. emergency treatment measures

1. In case of leakage accident of tetrahydrofuran, immediately cut off the leakage source, cover the leakage with sand, dry lime and other adsorption materials, and then clean it to a safe place.
2. If poisoning symptoms occur after contact with tetrahydrofuran, the patient should be moved to a ventilated place immediately to keep the respiratory tract unobstructed and sent to hospital for treatment in time.

In short, in the field of chemical production raw materials, the storage and transportation of tetrahydrofuran need to strictly comply with relevant safety regulations, and take effective measures to ensure the safety and health of personnel. At the same time, enterprises should strengthen the safety training and education of employees, improve the safety awareness and operation skills of employees, and ensure the safety and quality in the production process.
