Read： 1081 Time：12months ago Source：Transform the World with Simplicity

Vinyl acetate (Acetate, referred to as VAC) is a common organic chemical raw materials, widely used in polymer production, coatings, adhesives and other fields. Due to its flammable and toxic properties, vinyl acetate requires strict compliance with safety regulations during storage and transportation. In this paper, the specifications for safe storage and transport of vinyl acetate are described in detail.

1. the physical and chemical properties of vinyl acetate

vinyl acetate is a colorless and transparent liquid with a pungent odor. Its molecular formula is C4H6O2, structural formula is CH3COOCH = CH2. Vinyl acetate is flammable and can form an explosive mixture when mixed with air, which can cause combustion and explosion when exposed to open flame and high heat. In addition, vinyl acetate is also toxic, irritating and anesthetic to the human body, and can cause damage to the central nervous system, respiratory tract and skin.

2. vinyl acetate storage specification

1. The storage place should be selected in a cool, well-ventilated place away from fire, and avoid direct sunlight. The storage temperature generally does not exceed 30 ° C, and the relative humidity does not exceed 80%.
2. The storage container should be made of stainless steel or carbon steel, and avoid the use of aluminum, copper and other metal containers to avoid chemical reactions. The container should be well sealed to prevent leakage.
3. The storage site shall be equipped with fire fighting equipment and leakage emergency treatment equipment, such as fire extinguisher, sand, linoleum, etc.
4. During the storage process, the tightness of the container and pipeline should be checked regularly, and the leakage should be dealt with in time.

3. vinyl acetate transport specifications

1. Transport vehicles should meet the requirements of relevant laws and regulations, with dangerous goods transport qualifications, drivers and escorts should be professionally trained and certified.
2. In the process of transportation, it should keep running smoothly, avoid violent vibration, collision and friction, and prevent package damage.
3. Transportation vehicles shall be equipped with fire fighting equipment and leakage emergency treatment equipment, such as fire extinguishers and leakage sealing bags.
4. During transportation, high temperature and open fire should be avoided, and it is forbidden to mix with oxidants, acids, alkali metals, etc.
5. During transportation, the goods shall be inspected regularly and any abnormality shall be handled in time.

4. vinyl acetate safety operation specification

1. Operators should be professionally trained to understand the nature of vinyl acetate and safety operation procedures.
2. Wear protective clothing, gloves, goggles and other personal protective equipment during operation to avoid direct contact with vinyl acetate.
3. The operation site should be well ventilated to avoid high concentration of vinyl acetate vapor.
4. During operation, parameters such as temperature and pressure should be strictly controlled to avoid abnormal conditions such as overtemperature and overpressure.
5. After the operation, the site should be cleaned in time, and the wastes should be classified and stored to avoid environmental pollution.

5. vinyl acetate emergency treatment measures

1. skin contact: immediately take off the 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: gargle with water and drink milk or egg white. Seek medical attention.

In short, vinyl acetate, as a common organic chemical raw material, needs to strictly abide by safety regulations during storage and transportation to ensure the safety of personnel and the environment. By understanding the nature of vinyl acetate and safe operation procedures, strengthening personal protection and emergency treatment measures can effectively reduce safety risks and ensure the safety and stability of production.
