R22 in the field of chemical production of raw materials in the safety of storage and transportation specifications

1. Introduction

R22 is a common chemical production of raw materials, widely used in refrigeration, air conditioning and other fields. However, due to its flammable and toxic properties, it is necessary to strictly comply with relevant safety regulations during storage and transportation to ensure the safety of personnel and the environment. This article will detail the safety storage and transportation specifications of R22 in the field of chemical production raw materials. The physical and chemical properties of the

2. R22

R22 is a colorless, odorless, non-flammable, non-explosive gas, the chemical name is difluorochloromethane, and the molecular formula is CHClF2. It has low toxicity, but it will react with certain materials under high temperature and high pressure to produce toxic gases. Therefore, special attention is required during storage and transportation.

3. R22 safety storage specification

1. Storage facilities requirements: R22 should be stored in a cool, dry, well-ventilated special warehouse, the warehouse should be equipped with fire fighting equipment and leakage emergency treatment equipment. Storage facilities should be kept away from fire and heat sources, and avoid direct sunlight.
2. Storage container requirements: R22 should be stored in a dedicated steel cylinder or container. The container should comply with relevant national standards and be inspected and maintained regularly. The storage container shall be marked with information such as name, specification and weight.
3. Storage limit requirements: According to the regulations of the State Administration of Safety Supervision, the storage capacity of R22 should not exceed 30 tons.

4. R22 safety transportation specification

1. Transportation vehicle requirements: R22 should be transported by special transportation vehicles, which should comply with relevant national standards, and be equipped with fire fighting equipment and leakage emergency treatment equipment. Transport vehicles should be marked with the name, specifications and weight and other information.
2. Requirements for transportation personnel: transportation personnel should undergo professional training, understand the nature of R22 and safe operation procedures, and master the use of fire fighting equipment and leakage emergency treatment equipment.
3. Requirements for transportation route: The transportation route shall be a section with smooth roads, convenient transportation and far away from residential areas, and avoid staying in densely populated areas and open fire areas.
4. Transportation limit requirements: According to the regulations of the State Administration of Work Safety, the transportation volume of R22 should not exceed 10 tons.

5. R22 Leakage Emergency Treatment Specification

1. Leakage Treatment: When R22 leakage is found, the emergency treatment plan should be started immediately, measures should be taken to prevent the leakage from spreading, and the leakage area should be ventilated. If the leakage is large, immediately call the police and seek the help of a professional rescue team.
2. Personnel protection: When dealing with leakage accidents, professional protective clothing and respirators should be worn to avoid direct contact with leakage. If discomfort occurs after contact with the leak, seek medical treatment immediately.

6. conclusion

R22 as a common chemical production raw material, in the storage and transportation process need to strictly abide by the relevant safety regulations to ensure the safety of personnel and the environment. By understanding the physical and chemical properties of R22, mastering its safety storage and transportation specifications, and leakage emergency treatment specifications, it can effectively prevent the occurrence of safety accidents and ensure the smooth progress of the chemical production process.
