DGR (Dangerous Goods Regulations)



While Transporting the certain goods which are harmful and to make the transport safe and secure. IATA classified all these dangerous goods into nine classes. Dangerous Goods International (DGI) is a global logistics company that specializes in the transportation of hazardous goods worldwide.


Class 1 - Explosives


An explosive is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure


Sub - Divisions :

Division 1.1: Mass explosion hazard 


Division 1.2: Projection hazard only


Division 1.3: Fire hazard and minor blast or minor projection hazard 


Division 1.4: Minimal hazard 


Division 1.5: Blasting agents


Division 1.6: Very insensitive detonating articles


Examples :

Ammunition

Fireworks

Flares

TNT

RDX

Airbag Inflators



Class 2 - Gases


Gases are defined by dangerous goods regulations as substances that have a vapor pressure of 300 kPa (Kilopascal) or greater at 50°C (Celsius) or which are completely gaseous at 20°c at standard atmospheric pressure, and items containing these substances. The class encompasses compressed gases, liquefied gases, dissolved gases, refrigerated liquefied gases, mixtures of one or more gases with one or more vapors of substances of other classes, articles charged with a gas and aerosols.


Sub - Divisions :

Division 2.1: Flammable gases


Division 2.2: Non-flammable, Non-toxic gases


Division 2.3: Toxic gases


Examples :

Aerosols

Compressed Air

Hydrocarbon Gas-Powered Devices

Fire extinguishers

Insecticide gases

Lighters

Hydrogen compounds

Oxygen compounds

Natural Gas

Oil Gas

Petroleum Gas

Butane

Propane

Ethane

Methane



Class 3 - Flammable Liquids


Flammable liquids such as mixtures of liquids, liquids containing solids in solution or suspension which give off a flammable vapor at temperatures not more than 60-65°C, liquids offered for transport at temperatures above their flash point or substances which are transported at high temperatures in a liquid state and which give off a flammable vapor at a temperature below the maximum transport temperature.


Sub - Divisions :

This class don't have any sub-divisions but has Packing Groups depending on the boiling point and Flashpoint.


Packing Group 1: Boiling point below 35º

Packing Group 2: Boiling point above 35º C & Flashpoint < 23º

Packing Group 3: Boiling point above 35º C & Flashpoint > 23º C and < 60º C


Examples :

Alcohols

Aviation fuel

Diesel fuel

Gasoline / Petrol

Perfumes

Liquid biofuels

Copper-based pesticides

Gas oil

Shale oil

Heating oil

Kerosene

Resins



Class 4 - Flammable Solids

Solids, Which can spontaneous combustion than ordinary combustible materials such as wood and paper.  The burning may be severe and rapid, generating high temperatures. This is usually due to a number of factors like self-reactive, heat up while contacting with air, exothermic reaction.


Sub - Divisions :

Division 4.1: Flammable solids.


Division 4.2: Substances liable to spontaneous combustion.


Division 4.3: Substances which, in contact with water, emit flammable gases.


Examples :

Alkali metals

Metal powders

Firelighters

Matches

Activated carbon

Celluloid

Oily cotton waste

Desensitized explosives

Naphthalene

Metaldehyde

Phosphorus

Sulphur

Camphor

Sodium batteries



Class 5 - Oxidising Agents and Organic peroxides

Substances that can cause or be a part of combustion typically by yielding oxygen as a product of redox chemical reactions. Organic peroxide is a substance formed of organic compounds that are derivative of hydrogen peroxide. where one or both hydrogen atoms of the chemical structure have been replaced by organic radicals. Organic peroxides are unstable.


Sub - Divisions :

Division 5.1: Oxidizing substances


Division 5.2: Organic peroxides


Examples :

Chemical oxygen generators

Chlorates

Nitrates

Nitrites

Permanganates

Persulphates

Ammonium dichromate

Ammonium nitrate

Ammonium persulphate

Calcium nitrate

Calcium peroxide

Hydrogen peroxide

Magnesium peroxide

Lead nitrate

Lithium hypochlorite

Potassium chlorate

Potassium nitrate

Potassium chlorate

Potassium perchlorate

Sodium nitrate

Sodium persulphate



Class 6 - Toxic and Infectious substances

Toxic substances are the substances that are liable either to cause death or serious injury or harm human health by swallowing, inhaling, or by skin contact. Infectious substances are substances that are known or expected to contain pathogens.


Sub - Divisions :

Division 6.1: Toxic substances


Division 6.2: Infectious substances


Examples :

Medical waste

Clinical waste

Tear gas substances

Dyes

Carbamate pesticides

Chloroform

Biological cultures / samples / specimens

Medical cultures / samples / specimens

Beryllium/ beryllium compounds

Lead compounds

Mercury compounds

Nicotine/nicotine compounds

Selenium compounds

Antimony

Ammonium metavanadate

Adiponitrile



Class 7 - Radioactive Materials

Radioactive materials are materials that have unstable radionuclides atoms and can emit ionizing radiation. Depending on the type of radiation and time of exposure this can make a severe harm to human health.


Sub - Divisions :

NO SUB-DIVISIONS


Examples :

Radioactive ores

Medical isotopes

Yellowcake

Density gauges

Mixed fission products

Surface contaminated objects

Caesium radionuclides/isotopes

Iridium radionuclides/isotopes

Americium radionuclides/isotopes

Plutonium radionuclides/isotopes

Radium radionuclides/isotopes

Thorium radionuclides/isotopes

Uranium radionuclides/isotopes

Depleted uranium / depleted uranium products

Uranium hexafluoride

Enriched Uranium



Class 8 - Corrosive Materials

Corrosives are the substances that can affect other substances when it comes into contact with them. It can also cause high damage to living tissues after making contact. Corrosions are highly reactive substances. Corrosives can described as either acids or alkalis.


Sub - Divisions :

NO SUB-DIVISIONS


Examples :

Acids/acid solutions

Batteries

Battery fluid

Fuel cell cartridges

Fire extinguisher charges

Paints

Alkylphenols

Amines

Polyamines

Sulfides

Polysulphides

Chlorides

Phenol/carbolic acid

Hydrofluoric acid

Hydrochloric acid

Sulfuric acid

Nitric acid

Sludge acid

Hydrogen fluoride

Iodine
