How to properly use dangerous goods packaging is a major issue concerning the safety of people's lives, property and the environment during transportation, storage and use. For the use of export dangerous goods packaging, the inspection and quarantine department has strict requirements, but nevertheless In actual use, there are often some problems, especially the recent accidents involving the inspection of dangerous goods leaked by closed steel drums that have not been inspected by the inspection and quarantine department to Hong Kong, resulting in personal injury, giving us the country and related The company has caused great reputation and economic losses, and it has also sounded the alarm for the illegal use of dangerous goods packaging.
At present, the problems in the packaging of dangerous goods for export are mainly reflected in the following six aspects:
1. The package is incompatible with the contents it contains.
Incompatibility means that the packaging container will chemically react with the dangerous goods it contains, which will reduce the strength of the packaging and even damage the packaging, resulting in leakage of contents and accidents. If some materials that are corrosive to metals are packed in ordinary steel drums, they will corrode steel drums and cause leakage.
2. The packaging used is not suitable
Packaging is not suitable for the main performance:
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. For example, the maximum weight of the packaging design is 25kg, but the actual loading of more than 25kg of contents is In addition, if the package design stipulates that the specific gravity of the contents of the package cannot exceed 1.2, the actual proportion of the package is more than 1.2 contents.
2. Low-risk packages contain dangerous goods that require high-class packaging. For example, dangerous goods that require Class I packaging for a dangerous product are actually shipped in Class II or Class III packaging.
3. The package without venting holes transports dangerous goods that will release gas during storage and transportation. For example, hydrogen peroxide is placed in a plastic can without venting holes, which easily causes plastic cans to leak during storage and transportation. .
4. The weight or volume of the dangerous goods contained in the packaging container exceeds the maximum limit of the international regulations for the transport of dangerous goods. If the weight of a piece of a certain packaged material is not more than 30kg in accordance with international regulations, it has actually exceeded 30kg.
3. Improper use of packaging
Improper use of packaging is mainly manifested in:
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 causes dangerous goods to leak during storage and transportation.
3. The package corrodes or damages the outer surface of the package when it is loaded with dangerous goods.
4. 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 use because it is not used 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.
V. Use packaging that has not passed the inspection
The package is not tested for performance prior to use.
Six. Packaging mark error
The packaging mark is inconsistent with the actual packaging. For example, for the container bag with the coating film and the inner liner, mark 13H2 (actually it should be 13H4). There are even no marks on the packaging.
For the above phenomena, it will cause potential safety hazards and delays in shipment. In addition, there may be major losses in people’s lives and property such as explosions, burning, poisoning, etc. Therefore, we should not take lightly on the above issues and should cause enough Value.
In view of the problems existing in the current packaging process, the inspection and quarantine department recommends that the enterprises using dangerous goods packaging should start from the following aspects:
1. The physical and chemical properties of the dangerous goods must be fully understood to ensure that no chemical reaction is possible between the substance and the intended packaging. If you are using a package for the first time, you must do a compatibility test.
2. The type of dangerous goods, the UN number, and the type of packaging required must be determined. 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 and quarantine inspection and can produce the packaging performance certificate.
4. The meaning of the packaging mark printed on the packaging container must be correctly understood to ensure that the dangerous goods filled meet the requirements specified in the packaging mark.
5. It is necessary to ensure that 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. Must be familiar with the relevant requirements of China's entry-exit inspection and quarantine departments for the exit of dangerous goods and related procedures and international dangerous regulations.
In short, for the transportation of dangerous goods, the first thought should be highly valued, and the relevant professional knowledge should be learned well. The use of the package according to the regulations will ensure the safe transportation of dangerous goods. |
