Read： 1188 Time：12months ago Source：Transform the World with Simplicity

PVC (polyvinyl chloride) is a common raw material for chemical production, which is widely used in construction, pipeline, wire and cable and other fields. However, due to the nature and characteristics of PVC, there are certain safety risks during its storage and transportation. In order to ensure the safe storage and transportation of PVC, certain specifications and precautions need to be observed.

1. the nature and characteristics of PVC

PVC is a colorless, odorless, non-toxic plastic material, with high strength and hardness, acid and alkali resistance, corrosion resistance, and not easy to burn. However, factors such as high temperature, ultraviolet rays, and oxidants can cause PVC to decompose, produce toxic and harmful gases, and cause harm to the human body and the environment.

2. PVC safe storage specification

1. Storage place should be dry, ventilated, moisture-proof, avoid direct sunlight and high temperature environment.
2. PVC should be classified storage, different specifications, different batches of PVC should be stored separately to avoid confusion and cross contamination.
3. Avoid extrusion and collision of heavy objects during storage to avoid deformation and damage of PVC.
4. During the storage process, the quality and quantity of PVC should be checked regularly to find and deal with problems in time.

3. PVC safety transportation specifications

1. Before transportation, check whether the transportation vehicle and packaging are intact to ensure that there will be no leakage and damage during transportation.
2. During transportation, avoid high temperature, open flame and oxidant and other dangerous factors, so as not to cause PVC decomposition and combustion.
3. During transportation, it is necessary to maintain stable driving and avoid violent vibration and collision to avoid PVC damage and leakage.
4. After the arrival of the transportation, the goods shall be unloaded and counted in time, and the problems found shall be handled in time.

4. the safe use of PVC

1. Check the quality and specifications of PVC before use to ensure that it meets the requirements of use.
2. High temperature and ultraviolet radiation should be avoided during use to avoid decomposition and aging of PVC.
3. use should be in accordance with the provisions of the operating procedures, to avoid misoperation and illegal operation.
4. After use, the PVC should be cleaned and preserved in time to extend its service life.

5. PVC safety management

1. should establish a sound PVC management system and operating procedures, clear the safety requirements and responsibilities.
2. The supervision and inspection of PVC during storage, transportation and use should be strengthened to discover and deal with problems in time.
3. The training and education of employees should be strengthened to improve their safety awareness and operation skills.
4. Regular safety assessment and risk analysis shall be conducted, and timely measures shall be taken to eliminate potential safety hazards.

In short, in order to ensure the safe storage and transportation of PVC, it is necessary to comply with the corresponding specifications and precautions, strengthen management and supervision and inspection, and ensure that various safety measures are effectively implemented. At the same time, we should strengthen the training and education of employees, improve their safety awareness and operation skills, and jointly maintain the safety and stability of chemical production raw materials.
