1.1 This standard applies to the transport of dangerous goods in
class , division and name of the item number.
1.2 Where has the explosive , flammable , toxic, corrosive ,
radioactive and other properties in the transportation , handling and storage
of custody process, likely to cause personal injury and property damage and
need special protection goods are dangerous goods .
2 classification
Dangerous goods are divided into nine categories
Class 1 Explosives
Class 2 compressed gases and liquefied gases
Class 3 flammable liquids
Class 4 flammable solids substances liable to spontaneous
combustion and substances emitting flammable gases when wet.
Class 5 oxidizing substances and organic peroxides
Class 6 poisons and infectious substances
Class 7 radioactive substances [ZK]
Class 8 corrosives
Class 9 miscellaneous dangerous substances) [ZK]
3 Details
Class 1 Explosives
This category refers to goods under external action ( such as
heat, impact , etc. ) , chemical reactions can be dramatic , instantaneous
produce large amounts of gas and heat , making abrupt rise in ambient pressure
, exploded, causing damage to the surrounding environment of the items, but also
including no mass explosion hazard , but with the burning of pyrotechnic
articles , projectiles and small explosion hazard, or only one or several roles
heat, light , sound or smoke , etc. .
The class is divided into five cargo at risk .
Section 1 substances and articles which have a mass
explosion hazard
Section 2 substances and articles which have a
projection hazard but not a mass explosion hazard
National
Bureau of Standards, Implementation
Section 3 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
Section 4 substances and articles which present no significant
hazard
The entry of goods less dangerous , if ignited or ignited , its
dangerous effects largely confined within the package , but on the outside of
the package without significant risk .
Section 5 very insensitive substances
The nature of the cargo items is relatively stable , will not
explode in a fire test.
Class 2 compressed gases and liquefied
The type of goods means compressed, liquefied or dissolved under
pressure gas , and should meet one of the following two conditions :
The critical temperature is below
When the temperature of
The goods are divided into three categories :
Section1 flammable gases
Section2 non- Flammable gases
The term refers to goods toxic, non-flammable gases, including
combustion gases.
Section4 poisonous gases
Toxicity index of the entry of goods and Class 6 the same
toxicity indicators .
Class 3 Flammable Liquids
The type of goods means flammable liquids, liquid mixtures
containing solids or liquids , but because it does not include other types
of liquid hazardous properties listed . Closed cup flash point which is equal
to or lower than
The flash point is divided into three categories according to the
goods :
Section1 liquids in low flashpoint group
The term refers to goods closed cup test flash point below
Section2 liquids in intermediate flashpoint group
The term refers to goods closed cup flash point test at
Section3 liquids in high flashpoint group
Liquid
Category 4 flammable solids, flammable liquids and flammable when
wet
Item 1 flammable solids
The term refers to goods lighted low heat, impact and friction
sensitive and susceptible to an external source of ignition , burn rapidly and
may emit toxic fumes of toxic gases or solids , but does not include explosive
substances have been included .
Item 2 spontaneous items
The term refers to a low ignition point cargo , air is apt to
occur in the oxidation reaction heat released , the self- burning article .
Item 3 flammable when wet
The term refers to water or moisture goods occurs when violent
chemical reaction and emit large amounts of flammable gases and heat items.
Some do not need to open fire , which can burn or explode.
Class 5 oxidizers and organic peroxides
The first one oxidizer
The term refers to goods in a high oxidation state , with strong
oxidizing , easy to decompose and release oxygen and heat the material.
Peroxy
-containing organics including , itself not necessarily combustible, combustion
of combustibles can cause , with fluffy powder can form an explosive
combustible mixture to heat, sensitive to shock or friction.
Section 2 Organic peroxide
The term refers to molecules containing goods peroxy organic
compounds, flammable itself , easy decomposition, heat or friction are
extremely sensitive to vibration .
Class 6 toxic chemicals and infectious substances
Item 1 toxic chemicals
The term refers to goods after entering the body , accumulated to
a certain amount, biochemical or biological changes can occur in physics and
body fluids and tissues , disrupt or destroy the normal physiological function
of the body , causing temporary or permanent pathological state, and even life
threatening items . The median lethal dose oral intake : Solid LD50 ≤ 500mg/kg,
liquid LD50 ≤ 2000mg/kg; through skin contact 24h, the median lethal dose LD50
≤ 1000mg/kg; dust, fumes and vapors Inhalation LC50 LC50 ≤ 10mg / L of solid or
liquid , and the inclusion of dangerous goods pesticides.
Item 2 infectious substances
The term refers to goods containing pathogenic microorganisms
that can cause morbidity, and even physical death.
Class 7 radioactive substances
The type of goods means the radioactivity of greater than 7.4 ×
10 4Bq/kg items.
Class 8 corrosive substances
This category refers to goods and can cause damage to human
tissue burns solid or liquid metal and other items. Contact with skin necrosis
phenomenon seen in 4h, or when the temperature is
According to the chemical properties of this class of goods into
three :
Section1 Corrosives presenting acidic properties
Section2 Corrosives presenting alkalinous properties
Section3 other corrosives
Class 9 Miscellaneous
This category refers to the dangerous nature of the goods
presented during transport items are not included in the eight categories of
risk .
The goods are divided into two categories :
Item 1 magnetic items
When the term refers to the air transport of goods , the magnetic
field strength H of its package surface at any one pitch
Otherwise provided in paragraph 2 of article
The term refers to goods with anesthesia, poison or other similar
nature , the flight crew can cause emotional upset or discomfort , which affects
the proper execution of the mission , endangering flight safety items.
