Explosive Substances and Articles

Class 1 includes solid and liquid explosives as well as articles which contains explosives, e. g., shells or bombs. The definition of explosives following the dangerous goods classification is different from the definition for explosive following Directive 67/548/EEC. The heading of Class 1 covers  

It should be mentioned that substances which are not themselves explosive but which may form an explosive mixture of gas, vapor, or dust with air are not classified in Class 1 depending on their physical-chemical properties they are classified as gases in Class 2 and as Hquids in Class 3. 

Also excluded from Class 1 are water- or alcohol-wetted explosives of which the water or alcohol content exceeds the Hmits specified and those containing plasticizers (these explosives are assigned to Class 3 or Class 4.1) and those explosives which, on the basis of their predominant hazard, are assigned to Class 5.2. 

Devices containing explosive or pyrotechnic substances in such small quantity or of such a character that their inadvertent or accidental ignition or initiation during carriage would not cause any manifestation external to the device by projection, fire, smoke, heat, or loud noise are not subject to the requirements of Class 1. 

Division 1.1 Substances and articles which have a mass explosion hazard (a mass explosion is an explosion which affects almost the entire load virtually instantaneously).

United Nations, "Recommendations on the Transport of Dangerous Goods, Part I, Tests and Criteria for the Classificatioin of Explosive Substances and Articles", Report ST/SG/AC. 10/11/Rev 1, United Nations, New York, NY (1990). 

Upon classification, all explosives (including fireworks) are assigned to dangerous goods Class 1 in accordance with the Classification and Labelling of Explosives Regulations 1983 (CLER). Class 1 explosive substances and articles are then further classified according to their respective hazards. 

Explosive substances and articles in Class 1 are assigned to one of six divisions, depending on the type of hazard. An explosive substance is defined as a solid or liquid substance (or mixtures of substances) that is in itself capable by a chemical reaction of producing gas at such a temperature and pressure and at such a speed as to cause damage to the surroundings. Pyrotechnic substances are included even when they do not evolve gases. 

Fast pyrolysis liquid should not be shipped with other dangerous goods. Up to 5 litres [inner packaging] may be shipped with goods not subject to the provisions of ADR, provided they do not react dangerously with each other. Fast pyrolysis liquid shall not be packed together with substances and articles of Classes 1 and 5.2 [explosives substances and articles and organic peroxides respectively, other than hardeners and compound systems] and material of class 7 [radioactive material].
