Title: Safety storage and transportation specification
of saturated polyester resin in the field of chemical production raw materials
1. Introduction

saturated polyester resin (Polyester Resin) is a kind of polymer material widely used in the field of chemical production raw materials, with excellent physical properties and chemical stability. However, due to its special chemical properties, saturated polyester resin has certain safety hazards during storage and transportation. Therefore, it is essential to establish strict safety storage and transportation regulations.

Physical and Chemical Properties of 2. Saturated Polyester Resin

Saturated Polyester Resin is mainly prepared from dibasic acid and diol through polycondensation reaction, and has a linear molecular structure. Its physical properties include high viscosity, low volatility, excellent chemical resistance and thermal stability. However, saturated polyester resins also have certain toxicity, and prolonged exposure or inhalation of their vapors may cause harm to human health.

3. safety storage specifications

1. Storage facilities requirements: saturated polyester resin should be stored in a cool, dry, well-ventilated special warehouse, avoid direct sunlight and high temperature environment.
2. Storage container requirements: A special sealed container should be used to store saturated polyester resin to ensure that the container is intact and prevent leakage.
3. Storage security management: A sound storage security management system should be established, including regular inspections, monitoring facilities, emergency plans, etc., to ensure storage security.

4. safety transport specification

1. transport vehicle requirements: should use special chemical transport vehicles for saturated polyester resin transport, to ensure that the vehicle in line with relevant regulations and standards.
2. Transport packaging requirements: saturated polyester resin should be used in special sealed packaging to prevent leakage during transportation.
3. Transportation safety management: Safety management during transportation should be strengthened, and relevant regulations and standards should be observed to ensure transportation safety.

5. safety operation specifications

1. Operator requirements: The personnel who operate saturated polyester resin should undergo professional training to understand the nature of the product and safe operation procedures.
2. Operating environment requirements: The operating environment should have good ventilation conditions to avoid operation in confined spaces.
3. Operation process management: A sound operation process management system should be established to standardize the operation process and ensure operation safety.

6. emergency measures

1. Leakage treatment: in case of leakage of saturated polyester resin, measures should be taken immediately to stop the leakage and use special absorption materials to clean up the leakage.
2. First aid for personnel: If any personnel comes into contact with saturated polyester resin or has poisoning symptoms, they should be moved to a safe area immediately and first aid measures should be taken.
3. Fire protection measures: In the process of storage and transportation, in case of fire, appropriate fire extinguishing equipment should be selected according to the nature of saturated polyester resin.

7. conclusion

saturated polyester resin is widely used in the field of chemical production raw materials, but its safety storage and transportation regulations are very important. By understanding the physical and chemical properties of saturated polyester resin, strictly complying with storage, transportation and operation specifications, and strengthening emergency treatment measures, the safety of saturated polyester resin in the production and use process can be ensured, and the safety of personnel and the environment can be guaranteed.
