THE 9 CLASSES OF DANGEROUS GOODS

‘Dangerous goods’ are materials or items with hazardous properties which, if not properly controlled, present a potential hazard to human health and safety, infrastructure and/ or their means of transport.

The transportation of dangerous goods is controlled and governed by a variety of different regulatory regimes, operating at both the national and international levels. Prominent regulatory frameworks for the transportation of dangerous goods include the United Nations Recommendations on the Transport of Dangerous Goods, ICAO’s Technical Instructions, IATA’s Dangerous Goods Regulations and the IMO’s International Maritime Dangerous Goods Code. Collectively, these regulatory regimes mandate the means by which dangerous goods are to be handled, packaged, labelled and transported.

Regulatory frameworks incorporate comprehensive classification systems of hazards to provide a taxonomy of dangerous goods. Classification of dangerous goods is broken down into nine classes according to the type of danger materials or items present, click on a class to read more details;

  1. Explosives
  2. Gases
  3. Flammable Liquids
  4. Flammable Solids
  5. Oxidizing Substances
  6. Toxic & Infectious Substances
  7. Radioactive Material
  8. Corrosives
  9. Miscellaneous Dangerous Goods

 

The multitude of dangerous goods regimes across the world and the complexity of dangerous goods classifications and regulations render compliance a particularly difficult task. However DGI, as a logistics company specialising in dangerous goods, is well placed to deliver tailored solutions to all customer’s dangerous goods needs. DGI is proficient in all nine classes of dangerous goods and provides a range of services including packaging, packing, labelling, freight forwarding and training.

Explosives are materials or items which have the ability to rapidly conflagrate or detonate as a consequence of chemical reaction.

Sub-Divisions

Division 1.1: Substances and articles which have a mass explosion hazard

Division 1.2: Substances and articles which have a projection hazard but not a mass explosion hazard

Division 1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both

Division 1.4: Substances and articles which present no significant hazard; only a small hazard in the event of ignition or initiation during transport with any effects largely confined to the package

Division 1.5: Very insensitive substances which have a mass explosion hazard

Division 1.6: Extremely insensitive articles which do not have a mass explosion hazard

Reason for Regulation

Explosives are capable by chemical reaction of producing gases at temperatures, pressures and speeds as to cause catastrophic damage through force and/or of producing otherwise hazardous amounts of heat, light, sound, gas or smoke.
