Types of dangerous goods shipping

A Scope This standard applies to transport of dangerous goods in the class, and Division and the name of the number. Where have explosive, flammable, toxic, corrosive, radioactive and other properties, in the transport, handling and storage of custody process, likely to cause personal injury and property damage in need of special protection of the goods are dangerous goods. 2 Categories are divided into nine categories of dangerous goods Class 1 explosives (explosives) and Class 2 liquefied compressed gases (compressd gases and liquefied gases) Class 3 flammable liquids (flammable liquids) category 4 flammable solids, natural objects and the case of wet combustible materials (flammable solids substances liable to spontaneous combustion and substances emitting flammable gases when wet) Category 5 oxidizers and organic peroxides (oxidizing substances and organic peroxides) Class 6 toxic chemicals and infectious materials (poisons and infectious substances) Class 7 radioactive materials (radioactive substances) [ZK)] Class 8 corrosive chemicals (corrosives) Miscellaneous Class 9 (miscellaneous dangerous substances) [ZK)] 2.2 can be divided into several types (division) 3 Class 1 Explosives Class 3.1 refers to the outside world under the action of the goods (such as heat, impact, etc.), chemical reactions can be dramatic, instantaneous produce large amounts of gas and heat, so that the pressure around the rapidly rising, an explosion on the surrounding environment damage, and also the no explosion hazard, but with combustion, and smaller explosive projectile, or only produce heat, light, audio, or smoke effects such as one or more pyrotechnic articles. 3.2 The class is divided into five cargo at risk. 3.2.1 Item 1 with the overall explosion hazard substances and articles (substances and articles which have a mass explosion hazard) 3.2.2 item 2 with projectile hazard but no mass explosion hazard of substances and materials (substances and articles which have a projection hazard but not a mass explosion hazard) National Bureau of Standards 1986-10-07 Release 1987-07-01 3.2.3 the implementation of paragraph 3, with an explosion or fire hazard and a smaller less dangerous projectile, or both, but no explosion hazard of substances and materials (substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both, but not a mass explosion hazard) 3.2.4 Section 4 without significant risk of explosion substances and articles (substances and articles which present no significant hazard) The risk of smaller items of goods, if ignited or ignited, its role in most of the limited dangers inside packages, while the outside of packages without major risks. 3.2.5 Section 5 is not sensitive to the explosive material (very insensitive substances) relatively stable nature of the goods of this item, will not explode in the fire test. 4 Class 2 compressed gases and liquefied 4.1 class of goods means the compressed, liquefied or dissolved under pressure and should meet one of the following two conditions: 4.1.1 the critical temperature below 50 ℃, or 50 ℃, its vapor pressure greater than 291kPa compressed or liquefied gas. 4.1.2 temperature is 21.1 ℃, the gas absolute pressure greater than 275kPa, or 51.4 ℃ when the gas is greater than 715kPa absolute pressure compressed gas; or 37.8 ℃, the Reid vapor pressure (reid vapour pressure) is greater than 274kPa of liquefied or dissolved under pressure. 4.2 The goods are divided into three categories: 4.2.1, paragraph 1 of flammable gases (flammable gases) 4.2.2 item 2 combustible gas (non  flammable gases) This item refers to non-toxic goods, flammable gases, including combustion gases . 4.2.3 Section 3 of toxic gases (poisonous gases) toxicity index of the item of goods and indicators of the same toxic 6. 5 Class 3 Flammable liquids Class 5.1 cargo refers to flammable liquids, liquid mixtures containing solids or liquids, but not included due to its hazardous properties of other types of liquids. The closed cup flash point test is equal to or lower than 61 ℃, but different modes of transport may determine the mode of transport for the flash point, and not lower than 45 ℃. 5.2 The class of goods, according to flash point is divided into three: 5.2.1, paragraph 1 of low flash point liquids (liquids in low flashpoint group) refers to goods of this item closed cup flash point lower than -18 ℃ test liquid. 5.2.2 item 2 flash point liquids (liquids in intermediate flashpoint group) refers to goods of this item closed cup flash point test at -18 ℃ to <23 ℃ of liquid. 5.2.3 paragraph 3, the high flash point liquid (liquids in high flashpoint group) refers to goods of this item closed cup flash point test at 23 ℃ to 61 ℃ of liquid. 6, Category 4 flammable solids, flammable substances and combustible materials encountered wet flammable solids 6.1, paragraph 1 means the burning of the item of goods is low, heat, impact and friction sensitive and vulnerable to external fire ignited, burn rapidly, and may emit toxic smoke or toxic gases, solid, but not included in explosive substances. 6.2 Section 2 of this item of goods means the goods spontaneous ignition point is low, in the air prone to oxidation, heat release, while the self-burning items. 6.3 The case of the first three wet-flammable goods means the item with water or damp, the occurrence of severe reaction, release of flammable gases and heat a large number of items. Some do not need fire, that can burn or explode. 7 5 oxidizers and organic peroxides Class 7.1, paragraph 1 of this item of goods means the oxidizer in a high oxidation state, with strong oxidizing and easy to decompose and release oxygen and heat of the material. Including organic matter with peroxide, which itself does not necessarily combustible, but can lead to fuel combustion, and loose powder can form explosive mixture of fuel to heat, shock or friction sensitive. 7.2 Section 2 of this item of goods means the organic peroxide molecules containing organic peroxide, which itself is flammable and explosive, easily decomposed by heat, shock or friction sensitive. Class 6 8 toxic chemicals and infectious materials 8.1, paragraph 1 means the toxic chemicals into the body of the item of goods, the accumulated a certain amount of body fluids and tissues can occur with biochemical or biological role of physics change, disruption or destruction of the body normal physiological function, causing temporary or persistent pathological states, and even life-threatening items. Median lethal dose by oral intake: Solid LD50 ≤ 500mg/kg, liquid LD50 ≤ 2000mg/kg; through skin contact 24h, median lethal dose LD50 ≤ 1000mg/kg; dust, smoke and steam inhalation median lethal concentration LC50 ≤ 10mg / L of Solid or liquid, and the List of dangerous goods included in the pesticide. 8.2 No. 2 infectious materials containing the items of goods means pathogenic microorganisms that can cause illness and even death matter. 9 Class 7 radioactive materials in this class of goods means the specific activity greater than 7.4 × 10 4Bq/kg items. 10 Class 8 corrosive substances 10.1 class of goods means the metal can burn human tissue and other items damaged by solids or liquids. Contact with the skin necrosis seen in the phenomena occur within 4h, or the temperature at 55 ℃, 20 steel on the surface of uniform corrosion rate of more than 6.25mm / a solid or liquid. 10.2 The class is divided into three chemical properties of the goods by: 10.2.1 the first one acidic corrosive substances (Corrosives presenting acidic properties) 10.2.1, paragraph 2 alkaline corrosive substances (Corrosives presenting alkalinous properties) 10.2.3 Item 3 Other corrosive substances (other corrosives) 11 Class 9 Miscellaneous 11.1 The class of goods in transit means dangerous nature of the show is not included in the above eight categories of dangerous goods. 11.2 The goods are divided into two classes: the first one magnetic article 11.2.1 of this item refers to air transport of goods, its package of any one dot pitch surface magnetic field strength of 2.1m Department H ≥ 0.159A / m. 11.2.2 the provisions of paragraph 2 separate items of goods means the item has a narcotic, poison or other similar nature, can cause emotional irritability or not the flight crew, which affect the correct implementation of the mission, endangering the safety of flight. 12 Dangerous goods 12.1 Number Name Number Name Number the composition of dangerous goods composed of five digits, that a class of dangerous goods, item number and serial number. 12.3 12.2 number of the representation of each number used to specify a number of dangerous goods, but its basically the same nature, transportation and fire fighting, first aid the same dangerous goods can also use the same number. 12.4 instance name × × ×, is a Class 4, No. 3, Shun No. 100, the name of number is 43100. The numbers show that the dangerous goods is a Class 4 No. 3 encountered wet combustible materials
