Common problems in exporting dangerous goods packaging and measures to be taken

How to properly use dangerous goods packaging is a major issue concerning the safety of people's lives, property and environment during the transportation, storage and use of dangerous goods. The inspection and quarantine department has strict requirements for the use of export dangerous goods packaging. In the inspection and quarantine process, the common problems of exporting dangerous goods packaging are as follows:

1. The packaging container is incompatible with the contents it contains. Incompatibility means that the packaging container will chemically react with the dangerous goods it contains, thereby reducing the strength of the packaging and even causing the packaging to be damaged, resulting in leakage of contents and accidents. If some substances that are corrosive to metals are packed in ordinary steel drums, they will corrode steel drums, which will easily cause leakage of dangerous substances.

Second, the packaging used is not suitable, mainly in:

1. The weight or specific gravity of the dangerous goods contained in the packaging container exceeds the maximum weight or specific gravity of the contents that can be carried by the packaging; if the maximum weight of the packaging design is 25kg, the actual contents of more than 25kg are actually loaded; If the package design stipulates that the proportion of the contents of the package cannot exceed 1.2, the contents with a specific gravity exceeding 1.2 are actually loaded.

2. The packaging safety level does not meet the packaging category required by the dangerous goods. The dangerous goods are divided into three safety levels: Class I (height) dangerous goods, Class II (moderate) dangerous goods, Class III (low) dangerous goods. Correspondingly, the packaging used for these dangerous goods needs to meet the requirements of Class I, II and III respectively. For example, dangerous goods that require Class I packaging are dangerous goods, and dangerous goods manufacturers use Class II or Class III. Packed for shipment, the use of this package is unqualified.

3. The package without venting holes is used to install dangerous goods that will release gas during storage and transportation. For example, hydrogen peroxide is placed in a plastic tank without venting holes, and a large amount of gas generated during storage cannot be discharged. It is very easy to cause damage or even explosion of the package.

4. The weight or volume of the dangerous goods contained in the packaging container exceeds the maximum limit of the international regulations governing the transport of dangerous goods. For example, according to international regulations, the weight of a single package of a certain package shall not exceed 30 kg, but the actual load of more than 30 kg of goods.

Third, improper use of packaging, mainly due to improper operation of the staff in the process of loading and packaging, mainly including:

1. After the liquid dangerous goods are packed, the cover is not tightened, so that the dangerous goods leak during storage and transportation;

2. The packaged plastic bag has poor heat seal or loose mouth, which makes dangerous goods leak during storage and transportation;

3. Corrosion or damage to the outer surface of the package when loading dangerous goods.

Fourth, the use of packaging that has not passed the inspection. The physical and chemical properties of the packaging are not tested and passed the test by the national inspection agency before being used.

5. Use the package that has expired inspection. The package has passed the test before use, but it has exceeded the validity period of the test when it is needed for a long time. Generally, during storage, it will be corroded to varying degrees in nature, resulting in a decrease in packaging quality and a hidden danger in the storage and transportation of dangerous goods.

Sixth, the packaging mark is wrong. The packaging mark is inconsistent with the actual packaging. If the coated bag and the lining of the container bag are marked as 13H2 (actually it should be 13H4). There are even no marks on the packaging.

The above-mentioned problems in the use of dangerous goods packaging will leave hidden dangers and delays in shipments. In the meantime, explosions, burning, poisoning, etc. may occur, causing heavy losses to people's lives and property. In this regard, dangerous goods manufacturers should be highly valued:

1. Before using the packaging, the manufacturer should fully understand the physical and chemical properties of the dangerous goods and ensure that no chemical reaction occurs between the substance and the intended packaging materials.

2. Before packaging, determine the type of dangerous goods, the UN number, and the type of packaging required. For dangerous goods not listed in the international dangerous regulations, it must be sent to the inspection agency designated by the state to determine the type of dangerous goods, the UN number, and the type of packaging required.

3. It is necessary to use the packaging that has passed the inspection by the inspection and quarantine institution and has issued the packaging performance qualification list.

4. Correctly understand the meaning of the packaging marks printed on the packaging container to ensure that the dangerous goods filled meet the requirements specified in the packaging mark.

5. After the dangerous goods are filled, the sealing of the package is firm, without any leakage or leakage, the appearance is clean, and the weight meets the requirements of international dangerous regulations.

6. Familiar with the relevant requirements of China's entry-exit inspection and quarantine departments for the exit of dangerous goods, relevant procedures to be handled, and relevant contents of international dangerous regulations.

In short, for the packaging of dangerous goods, we must attach great importance to the idea, we must master the professional knowledge of packaging and use the packaging according to the regulations. Only in this way can we better ensure the safe transportation of dangerous goods.
