Read： 478 Time：13months ago Source：Transform the World with Simplicity

Polyvinyl acetate (Polyvinyl Acetate, referred to as PVAc) is a common chemical raw material, widely used in adhesives, coatings, textiles and other fields. Due to its special chemical properties, polyvinyl acetate needs to comply with certain safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safe storage and transportation specifications for polyvinyl acetate.

1.

Polyvinyl acetate is a colorless, transparent, elastic solid with high melting point and glass transition temperature. It has good water resistance, oil resistance, acid and alkali resistance, but not heat, solvent resistance. Under high temperature or acidic conditions, polyvinyl acetate will decompose and produce harmful gases.

2. safety storage specifications for polyvinyl acetate

1. The storage place should choose a dry, ventilated and cool place to avoid direct sunlight and high temperature environment.
2. The storage container shall be a container with good sealing performance to prevent the volatilization of polyvinyl acetate and the entry of external impurities.
3. The storage area should be away from fire and heat sources, and smoking and open fire operations are prohibited.
4. Regularly check the safety of the storage area to ensure that the storage equipment is in good condition and prevent leakage accidents.

3. polyvinyl acetate transportation specifications

1. Before transportation, check whether the packaging is intact to ensure that there is no leakage.
2. In the process of transportation, light loading and unloading should be carried out to avoid collision, extrusion and other external forces to prevent package damage.
3. Transport vehicles shall be equipped with safety facilities such as fire prevention, explosion-proof and anti-static, and drivers shall receive relevant safety training.
4. During transportation, it should be kept away from fire and heat sources, and it is forbidden to mix with oxidants, acids and other substances.

4. emergency treatment measures

1. In case of leakage accident, 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. In the event of a fire accident, immediately extinguish the fire with foam, dry powder and other fire extinguishers, and call the police for help.
3. If contact with polyvinyl acetate causes physical discomfort, immediately remove the contaminated clothing, rinse the contaminated area with plenty of water, and then seek medical treatment.

In short, in order to ensure the safety of polyvinyl acetate during storage and transportation, relevant safety regulations must be strictly observed and effective protective measures must be taken. By strengthening management and training, improving the safety awareness and operation skills of relevant personnel, the safety risks during the storage and transportation of polyvinyl acetate can be effectively reduced, and the safety of personnel and the environment can be guaranteed.
