Dangerous goods are classified into the following categories:
Explosive works of the first kind
Class 2 compressed gases and liquefied gases
Class 3 Flammable liquids
Class 4 Flammable solids, spontaneously flammable articles and moistened flammable articles
Class 5 oxidants and organic peroxides
Toxic and infectious substances of Class 6
Category 7 Radioactive substances

Category 9 Miscellaneous
The detailed solution is as follows:
Explosives of Class 1
This refers to the goods under the action of the outside world (such as heating, impact, etc.), can send and violent chemical reaction, instantaneous produces large amounts of gas and heat, the surrounding pressure rapid rise, explosion, damage to the environment, including no overall explosion danger, but it is burning and small mass ejection and explosion danger, Or pyrotechnic objects that produce only one or several effects, such as heat, light, sound or smoke.
This category of goods is divided into five categories according to risk:
Item 1 Substances and articles with an overall explosion hazard
Item 2 Substances and articles that present a risk of ejection but not a risk of mass explosion
Item 3 Substances and articles that present a risk of combustion and a risk of minor explosion or minor ejection, or both, but do not present an overall risk of explosion
Item 4 Explosive materials and articles without significant danger, the danger of the goods is small, in case of being ignited or detonated, its dangerous effect is mostly confined to the inside of the package, but there is no significant danger to the outside of the package.
Item 5 Very Insensitive Explosive Material) This cargo is relatively stable in nature and will not explode during fire tests.
Class 2 compressed gases and liquefied gases
This class of cargo refers to compressed, liquefied or pressurized dissolved gases, which shall comply with either of the following conditions: 1. Compressed or liquefied gases whose critical temperature is below 50 ° c or whose vapor pressure is greater than 294kPa at 50 ° c.
2, the temperature at 21.1℃, the gas ****** pressure is greater than 275kPa, or at 54.4℃, the gas ****** pressure is greater than 715kPa compressed gas; Or liquefied gas with Reid vapour pressure greater than 275kPa at 37.8 ° c or gas dissolved under pressure.
This category of goods is divided into three categories:
Item 1 Flammable gas
Item 2 Non-IGNitable GAS This cargo means ******, NON-ignitable gas, including combustive gas.
Item 3 Toxic Gas The toxicity index of this cargo is the same as that of Category 6.
Class 3 Flammable liquids
This class of goods refers to flammable liquids, liquid mixtures or liquids containing solid substances, but does not include liquids that have been placed in other classes because of their dangerous properties. Its closed cup test: flash point is equal to or lower than 61℃, but different modes of transportation can determine the applicable flash point of this mode of transportation, but not lower than 45℃.
This class of goods is divided into three categories according to flash point:
Item 1 Low Flash Point Liquids This cargo refers to liquids with a flash point lower than -18℃ in the closed cup test.
Flash point Liquids in Item 2 This cargo refers to liquids with a flash point of -18 ° C to less than 23 ° C in the closed cup test.
Item 3 High Flash Point Liquids This cargo refers to liquids with a flash point between 23 ° C and 61 ° C in the closed cup test.
Class 4 Flammable solids, spontaneously flammable articles and moistened flammable articles
Item 1 Flammable Solids The goods are solids with a low ignition point, sensitive to heat, impact and friction, easily ignited by external sources of fire, burning rapidly and likely to emit toxic fumes or gases, but do not include substances listed as explosives.
Item 2 Spontaneous combustion Articles This article refers to articles with a low spontaneous combustion point, which are prone to oxidizing reaction in the air and release heat, and thus spontaneously burn.
Item 3 Wet Flammable Articles This article refers to articles that, when exposed to water or moisture, undergo violent chemical reactions and give off a large amount of flammable gas and heat. Some burn and explode without an open flame.
Class 5 oxidants and organic peroxides
Item 1 Oxidant This cargo refers to a substance in a high oxidation state, which is highly oxidizing, easily decomposing and giving off oxygen and heat. Including inorganic substances containing peroxyls, which are not necessarily flammable themselves, but can lead to combustion of combustible materials; Can form explosive mixtures with loose powder combustibles, sensitive to heat, shock or friction.
Item 2 Organic peroxides This cargo refers to organic matter containing peroxyls in its molecular composition, which is flammable, explosive, easily decomposed and extremely sensitive to heat, vibration or friction.
Toxic and infectious substances of Class 6
Item 1 Toxic SUBSTANCE The term "Toxic substance" refers to the substance that, after entering the body, accumulates in a certain amount and can undergo biochemical or biophysical changes with body fluids and tissues, disturb or destroy the normal physiological function of the body, cause temporary or invasive pathological state, or even endanger life. Median lethal dose of oral ingestion: solid LD50≤500mg/kg, liquid LD50≤2000mg/kg; After 24 hours of skin contact, LD50≤1000mg/kg; Inhalation of dust, smoke and vapour to solids or liquids with a median lethal concentration of LC50≤10mg/L, and pesticides listed on the list of dangerous goods.
Item 2 Infectious Goods The goods refer to substances containing pathogenic microorganisms, which can cause sickness and even death.
Category 7 Radioactive Goods This category of goods refers to goods with a specific radioactive activity greater than 7.4×104 Bq/kg.
Class 8 Corrosive products
Goods in this category are solids or liquids that can burn human tissues and cause damage to metals or other objects. Visible necrosis occurs within 4h of contact with skin, or solid or liquid with a uniform annual corrosion rate of over 6.25mm/y on the surface of no. 20 steel at 55 ° c.
This class of goods is divided into three categories according to their chemical nature:
Item 1 Acid corrosive products
Item 2 Alkaline corrosive products
Item 3 Other corrosive products
Category 9 Miscellaneous
This CATEGORY OF GOODS refers to GOODS whose HAZARDOUS NATURE DURING TRANSPORT DOES NOT FALL WITHIN the ABOVE EIGHT categories OF HAZARDS. This category of goods is divided into two categories:
Item 1 Magnetic Goods This cargo refers to the magnetic field strength H≥0.159A/m at any point 2.1 m away from the surface of the package when transported by air.
Item 2 Articles otherwise specified This article refers to articles of anesthetic, toxic or other similar nature that can cause emotional restlessness or discomfort of flight crew members, thus affecting the correct performance of flight tasks and endangering flight safety.
