Read： 623 Time：14months ago Source：Transform the World with Simplicity

Dimethyl sulfoxide (DMSO) is a common chemical raw material. Because of its unique physical and chemical properties, it is widely used in medicine, pesticide, printing and dyeing, electronics and other industries. However, dimethyl sulfoxide has certain toxicity and irritation. If stored and transported improperly, it will cause harm to the environment and human health. Therefore, in order to ensure the safe use of dimethyl sulfoxide, the relevant storage and transportation regulations must be strictly observed.

1. the physical and chemical properties of dimethyl sulfoxide

dimethyl sulfoxide is a colorless and transparent liquid with a special odor. It has strong hygroscopicity and permeability, and can be miscible with water, alcohol, ether and other solvents. Dimethyl sulfoxide has a melting point of 18.4°C, a boiling point of 189°C and a flash point of 95°C. In addition, dimethyl sulfoxide has strong reducibility and is easily oxidized.

2. the hazardous
of dimethyl sulfoxide
dimethyl sulfoxide has certain toxicity and irritation. If it is exposed to or inhaled dimethyl sulfoxide vapor, it will cause irritation and damage to the human respiratory system, skin, and eyes. Long-term exposure to dimethyl sulfoxide may also cause diseases of the nervous system and digestive system. In addition, dimethyl sulfoxide is also harmful to the environment, which may cause pollution to water and soil.

3. storage specifications for dimethyl sulfoxide

In order to ensure the safe storage of dimethyl sulfoxide, the following specifications need to be observed:

1. The storage place should be dry, ventilated, cool, and away from open flames and heat sources.
2. The storage container shall be well sealed to prevent leakage and volatilization.
3. The storage area shall be provided with obvious safety signs and warning signs.
4. During storage, regular inspection and maintenance shall be carried out to ensure that the storage container is intact.

4. of dimethyl sulfoxide transportation specifications

In order to ensure the safe transportation of dimethyl sulfoxide, the following specifications need to be observed:

1. Transportation vehicles should have corresponding qualifications and certificates to ensure safety during transportation.
2. During transportation, it should be kept stable to avoid violent vibration and collision.
3. The transport container shall be well sealed to prevent leakage and volatilization.
4. Avoid high temperature and open fire environment during transportation, and keep away from heat and fire sources.
5. Obvious safety signs and warning signs shall be set during transportation.

5. safety precautions for the use of dimethyl sulfoxide

1. before use should understand the nature and safe use of dimethyl sulfoxide, wearing the appropriate protective equipment.
2. Keep good ventilation during use and avoid prolonged exposure to dimethyl sulfoxide vapor.
3. After use, the use place and tools should be cleaned in time to prevent the residual dimethyl sulfoxide from polluting the environment.
4. In case of leakage or contact accident, corresponding emergency measures shall be taken immediately and medical treatment shall be taken in time.

In short, dimethyl sulfoxide as a common chemical production raw materials, although it has certain toxicity and irritation, but as long as strictly abide by the relevant storage and transportation norms, strengthen the safe use of management, you can ensure its safe use, for medicine, pesticides, printing and dyeing, electronics and other industries to provide a strong guarantee.
