What are High Consequence Dangerous Goods?

In ADR/IMDG and IATA they are referred to as follows:

“High consequence dangerous goods are those which have the potential for misuse in a terrorist incident and which may, as a result, produce serious consequences such as mass casualties or mass destruction”. 

Information on this classification can be found in ADR, Chapter 1.10.5 (Table), IATA, Chapter and IMDG, Chapter 1.4.3.

The current list, which can vary between the above regulations, consists of some products in Class 1 (Explosives), Class 2 (Gases), Class 3 (Flammable Liquids), Classes 4.1, 4.2, 4.3 (flammable solids, spontaneously combustible and dangerous when wet), Class 5.1 (Oxidising liquids), Class 6.1 (Toxic substances), Class 6.2 Infectious substances of Category A), Class 7, (Radioactive material) and Class 8 (Corrosive substances).  Where there is a Packing Group these tend to be of Packing Group I (Maximum danger). 

Carriers, consignors and other participants (see ADR 1.4.2 and 1.4.3) have to ensure that a security plan is in place.  This plan should cover the following:

  1. Specific responsibilities allocated to competent and qualified personnel;
  2. Records must be kept of dangerous goods involved;
  3. Review of current procedures and assessment of security risk;
  4. Clear statement of measures that are to be taken to reduce security risks;
  5. Procedures for reporting and dealing with security risks and breaches
  6. Procedures for evaluation and testing security plans;
  7. Measures to ensure the physical security of transport information
  8. Measures to ensure that information relating to the transport operation contained in the plan is limited to those who need to have it.
