4.1 Appearance requirements:
4.1.1 The marks, logos and colored labels of dangerous goods cast, printed or pasted on the steel drums shall be accurate and clear, and comply with the relevant requirements of GR19433.1-2004, and the words "filled with nitrogen" shall be clearly marked. 4.F.2 The appearance of the package shall be clean. No residual contamination or leakage is allowed. 4.1.3 The package sealed with lead shall be sealed after on-site inspection by the delivery department. 4.2 The steel drums selected by the user unit shall be compatible with the nature of the dangerous goods transported, and their performance shall comply with the provisions of GB19453.1-2004.
4.3 The packaging grade of steel should be equal to or higher than the packaging grade required for the bagged goods. 4.4 In the following cases, a dangerous goods classification, grading and dangerous characteristics inspection report issued by an inspection agency recognized by the national quality supervision, inspection and quarantine department should be provided:

h) First export:
) When the national quality inspection department deems it necessary, 4.5 The first use of steel with internal coating or internal plating should provide a report of chemical compatibility test qualification for more than 6 months. 4.6 The steel drum is equipped with appropriate sealing separation. No matter what form of sealing is used, it should meet the tight hoop and sealing requirements. The wrench hoop also needs to lock the wrench with a pin:
4.7 Atmosphere filling requirements:
4.7.1 Nitrogen filling method: The nitrogen filling method of calcium carbide packaging must be appropriate. Generally, the method in Appendix A can be used, and other equivalent methods can be used. 4.7.2 Nitrogen filling material: pure nitrogen with nitrogen content of 99.99% (volume fraction) or more should be used. When using ammonia with nitrogen content of 99.9 (volume fraction), it must be dried to remove moisture. 4.8 Steel barrels must be stored in the warehouse before and after use and kept dry. :comGB19453.2--2004
4.9 The airtight seal of steel drums should be leak-free. 4.10 The volume fraction of acetylene in steel is not more than 1%. 5 Sampling

6.7, 2 Adjustment steps: Use an acetylene fast tester calibrated with standard acetylene gas, open the oxygen filling hole, and insert the exhaust pipe of the instrument from the oxygen filling hole into the package for measurement.
Identification rules
Enterprises using calcium carbide packaging steel drums should ensure that the calcium carbide packaging steel drums they use comply with the provisions of this standard and be identified by relevant inspection departments in accordance with this standard. Users of calcium carbide packaging products have the right to apply for acceptance and identification of the received packaging products in accordance with the provisions of this standard. :com7.1 Identification items
Identify item by item in accordance with the requirements of Chapter 4 and Section 6 of this standard. 7.2 Determination of batches
Calcium carbide packaging products should be identified in batches based on the order quantity, with the maximum order quantity not exceeding 5,000 pieces, and identified batch by batch. 7.3 Judgment rules
CB 19453.2—2004
Identify item by item in accordance with the requirements of the standard. If one package fails in each item, the item shall be judged as unqualified. If one item fails, the batch of packaging products shall be assessed as unqualified.
7.4 Disposal of unqualified batches
After the unqualified calcium carbide packages in the non-qualified batches are eliminated, they will be re-identified, and the strictness remains unchanged. ：comGB 19453.2—2004
A1 Negative pressure nitrogen filling method
Appendix A
(Informative Appendix)
Nitrogen filling method for calcium carbide packaging
Use a two-way valve to connect the package, vacuum pump and nitrogen pipe. First, close the nitrogen filling pipe, open the vacuum pump to extract the gas in the package, then close the vacuum pump, open the nitrogen filling pipe to fill nitrogen until positive pressure is generated in the package. A.2 Positive pressure nitrogen filling method
When filling calcium carbide, insert a nitrogen filling pipe into the bottom of the package, start filling the bottle to remove the mixed gas in the package from the bottom, then close the opening, and then fill nitrogen from the nitrogen filling hole on the top cover.
