DGR Classification SystemDGR Classification System
The physical state and physical properties of the
dangerous goods will affect how easily and safety
the goods can be handled in transport, how they
should be packaged and what hazards they
present, especially if spilled.

DGR Classification SystemDGR Classification System
The DGR also divides dangerous goods into :
SubstancesSubstances ArticlesArticles

• Dangerous Goods are divided into 9
hazard groups called classes .
– Classes 1, 2, 4, 5 and 6 are broken down into
“Divisions” due to hazard variation within
these classes.
• Classes are expressed by single-digit
numbers. (Example Class 7).
• Divisions are expressed by 2-digit
numbers. The first digit identifies the class
number and the second identifies the
division number within that class.
