Issues regarding the management of liquid chlorine cylinders

We are labels, handwritten and pasted on top; P

The Quality and Technical Supervision Bureau in Shandong once implemented electronic tags to go along with changes in the ownership of gas cylinders, in order to monitor the movement of each cylinder and ensure their safety. Electronic tags are stuck to the bottle body using Gorlaohao adhesive. All cylinder records and the usage status of cylinders are available online, which plays a role in overseeing cylinder inspections. But later on, electronic tags proved to be unreliable; they often got damaged, failed to read data properly, and were prone to falling off, so this rule was dropped. **The intention is good, but it’s a bit difficult to implement. There are many unexpected problems. 2D barcodes are essentially similar to the system used in supermarkets for managing products; they should be effective for tracking cylinders that come in and out of factories, as well as for managing the sales of liquid chlorine. However, they are less suitable for managing cylinder records. After all, cylinders are portable containers that move around constantly – they might be at my place today, at someone else’s place tomorrow, and possibly outside the province the day after that. It’s hard to say when they will return, and by the time they do, they won’t be in their original condition, the liquid chlorine inside them won’t be the same as it was before, and even the barcodes on them may have been torn off. Therefore, the documentation of gas cylinders should still be based on their steel codes; even the cylinder numbers marked on them are not reliable, so manual labor remains the most dependable method. For the sales management of liquid chlorine as a commodity, barcodes can be used to **simplify manual processes and reduce errors.

3# Huawei: “But later on, the electronic tags proved to be unreliable – they often got damaged, failed to read data properly, and were prone to falling off.” Could you explain this in more detail? Electronic tags can access the archival information of gas cylinders, facilitating inquiries and management by regulatory authorities. However, they have disadvantages such as high equipment costs and difficulties in equipment maintenance. Although the actual management practices vary from province to province, the use of electronic tags is the prevailing trend in the management of liquid chlorine gas cylinders. Our company is comparing various management plans for liquid chlorine cylinders, and we hope everyone can help with the analysis.

Once the chip is damaged, all the data is lost. Second: Electronic tags can also be easily replaced, thereby altering the original records. Third: The transfer of gas cylinders and the granting of permissions involve issues related to property rights; such actions that interfere with market operations are met with strong resistance. Fourth: There is no protection for electronic tags on the side of liquid chlorine users, nor is there any consideration given to the uses of these electronic tags; as a result, users cannot access the electronic information related to the gas cylinders, which makes management difficult. Fifth: **When introducing something new, it is necessary to consider the level of feasibility; advanced network technologies should not be adopted blindly.** Sixth: Even with electronic tags, it is still impossible to prevent cylinders from being refilled and reused arbitrarily without proper management through those tags. In terms of the reliability of data storage media, optical storage (CDs) is inferior to magnetic media (hard drives); magnetic media are inferior to paper media; printed texts are inferior to handwritten ones; handwritten texts are inferior to inscriptions on stone; and inscriptions on stone are inferior to information stored permanently in the human mind!
