Safety of Acrylonitrile Storage and Transportation Specification

1. Introduction

Acrylonitrile is an important organic chemical raw material, widely used in synthetic fibers, plastics, rubber and other fields. However, acrylonitrile is toxic and flammable, so strict safety regulations need to be observed during storage and transportation to ensure the safety of personnel and the environment. This paper will detail the specification of safe storage and transportation of acrylonitrile.

2. the physical and chemical properties of acrylonitrile

acrylonitrile is a colorless transparent liquid with pungent odor. It has a melting point of -83°C, a boiling point of 107.7°C and a density of 0.806g/cm³. Acrylonitrile is flammable, and in case of open flame, high heat or contact with oxidant, there is a danger of combustion and explosion. Acrylonitrile is toxic and can cause harm to the body after inhalation, oral administration or absorption through the skin.

3. acrylonitrile storage specification

1. storage place should be selected in a cool, ventilated, dry place, away from fire, heat source. The storage temperature shall not exceed 30 ℃ and the relative humidity shall not exceed 80%.
2. The storage container shall be made of stainless steel or carbon steel, avoiding the use of aluminum, copper and other metal containers. The container should be well sealed to prevent leakage.
3. The storage site shall be equipped with leakage emergency treatment equipment, such as adsorption material, neutralizing agent, etc., to deal with possible leakage accidents.
4. The storage area shall be provided with obvious safety warning signs, and smoking and open fire shall be prohibited.

4. acrylonitrile transport specification

1. transport vehicles should meet the requirements of dangerous chemicals transport, with the corresponding fire, explosion, anti-static and other safety facilities.
2. Keep running smoothly during transportation to avoid severe vibration, collision and friction.
3. During transportation, keep away from fire, high heat and other dangerous sources, and avoid direct sunlight.
4. Transport personnel should be professionally trained to understand the physical and chemical properties of acrylonitrile and emergency treatment measures.

5. emergency treatment measures

1. skin contact: immediately take off contaminated clothing, rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.
2. Eye contact: Lift the eyelid immediately and rinse thoroughly with plenty of flowing water or normal saline for at least 15 minutes. Seek medical attention.
3. Inhalation: Quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention.
4. Ingestion: Drink plenty of warm water and induce vomiting. Seek medical attention.

6. conclusion

acrylonitrile as an important chemical raw material, its safety and standardization of storage and transportation are very important. In order to ensure the safety of personnel and the environment, the storage and transportation regulations of acrylonitrile must be strictly observed. The risk of acrylonitrile leakage accident can be effectively reduced by taking reasonable safety measures and emergency treatment measures.
