What are Dangerous goods?

Any material which poses threat to human health and environment during packing, storage, and transportation. Examples of Dangerous goods used in daily life: Nail polish, deodorant, Lawn movers, crackers, all electronic products with batteries etc.

Classification of Dangerous goods:

All the dangerous goods are classified to below 9 classes and some of these 9 classes are again classified to Divisions:

  • Class 1: Explosives: Products which detonate during chemical reaction, example: crackers
    Divisions:
    • 1.1: Substances and articles which have a mass explosion hazard
    • 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard
    • 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both
    • 1.4: Substances and articles which present no significant hazard; only a small hazard in the event of ignition during transport with any effects largely confined to the package
    • 1.5: Very insensitive substances which have a mass explosion hazard
    • 1.6: Extremely insensitive articles which do not have a mass explosion hazard
  • Class 2: Gases: products in gaseous state which can be toxic and nontoxic (Fire extinguishers)
    Divisions:
    • 2.1: Flammable gases
    • 2.2: Non-flammable, non-toxic gases
    • 2.3: Toxic gases
  • Class 3: Flammable liquids: liquid, a mixture of liquids, or liquids containing solids that require a much lower temperature than others to ignite. Example: perfumery products, Nail polish remover.
    Divisions:
  • Class 4: Flammable solids: are easily combustible and likely to contribute to fires during transportation. Example: Seed cake
    Divisions:
    • 4.1 Flammable solids: These will burn easily than normal combustible materials. The burning of flammable solids is also fierce and rapid; they are also incredibly dangerous because they can decompose explosively, burn vigorously, or produce toxic gases
    • 4.2 Spontaneously combustible: These can be either solids or liquids. They ignite spontaneously when in contact with oxygen
    • 4.3 Dangerous when wet: These goods react with water to generate flammable gas that can be ignited by the heat of the reaction
  • Class 5: Oxidizing agents & organic peroxides: are often extremely reactive because of their high oxygen content. Example: Hydrogen peroxide
    Divisions:
    • 5.1 Oxidising Agents: are substances that can cause or contribute to combustion as a product of chemical reactions
    • 5.2 Organic peroxides: are materials makes them extremely liable to ignition. They are unstable and can be explosive
  • Class 6: Toxins and infectious substances: are substances like medical wastes
    Divisions:
    • 6.1 Toxins: are liable to cause death because they’re, as the name suggests, toxic
    • 6.2 Infectious substances: are micro-organisms that cause infectious diseases in humans or animals, otherwise known as pathogens
  • Class 7: Radioactive material: are unstable atoms emitting harmful radiation. Example: Smoke detectors.
  • Class 8: Corrosive: are highly reactive materials that produce positive chemical effects which corrode human, or material comes in contact with them. Example: Chlorides
  • Class 9: Miscellaneous dangerous goods: covers substances that present a danger not covered in the other classes. Example: Lithium batteries, Air bags etc.

Finally, these dangerous goods are classified and identified by specific UN number (example: UN 1993: flammable liquid N.O.S) when transported by ROAD, RAIL, SEA and AIR and are subjected to multiple regulations.
