In addition to explosives, compressed gas, liquefied gas, infectious and radioactive items packaging, the packing of the dangerous goods according to its protective performance is divided into:

I kind of packing is suitable for holding highly dangerous goods;

Class II packing is suitable for holding moderate dangerous goods;

Class III packing is suitable for holding low dangerous goods.

Protective performance of all kinds of packaging should reach demanded to see the rules annex 3 "packaging methods, models, specifications, and performance test". The required by the various dangerous goods packaging category to see the schedule of the goods.

First of all, the packing of the dangerous goods (pressure vessels and radioactive goods packaging otherwise specified) shall be in accordance with annex 3 of the rules of the performance test. Declare and shipper of dangerous goods should hold issued by packing inspection institution authorized by the ministry of transportation of dangerous goods packaging inspection certificate "(three) format, meets the requirements, can use;

Second, pressure vessels and radioactive substances containing dangerous goods packaging shall comply with the provisions of the competent department of the state of pressure vessel should hold the commodity inspection authorities or the boiler pressure vessel inspection agencies to issue the inspection certificate of quality; Radioactive substances should hold issued by the health and epidemic prevention departments "radioactive goods package radiation inspection certificate" (four) format.

Again, according to the characteristics of the nature of the dangerous goods and water transportation, the packaging should satisfy the following basic requirements:

(a) the packaging specification, type and single quality (weight) shall facilitate loading and unloading or transport;

(2) the packing material, type and methods (including packing seal) should be adapted to the nature of the cargo of quasi. Absorbed liner material and inside packing material to be compatible with the nature of cargo of quasi, and can protect the goods moving and leakage;

(3) the package should have a certain strength, can withstand transportation of general risk. Low boiling point cargo containers, its strength must be enough safety coefficient, in order to withstand the high vapor pressure of the container may be produced;

(4) the packing should be dry, clean and no pollution, and can withstand transportation in the process of the change of temperature and humidity;

(5) the container holding the liquid goods, must have enough ullage reserve (volume), to prevent the container deformation caused by temperature changes in the transportation or leakage of goods;

(6) holding the following dangerous goods packaging should meet the requirements of hermetic seal:
