How are packing groups identified for hazardous materials?

Packing groups are crucial for the classification of hazardous materials as they indicate the degree of danger posed by the materials during transportation. The identification of packing groups is done using Roman numerals, which helps categorize hazardous materials into three distinct groups based on their level of risk.

Group I indicates substances presenting the highest level of danger (e.g., explosives), while Group II represents moderate danger, and Group III signifies lower danger levels. This system provides clear guidance for handlers of these materials regarding the risks involved and the necessary precautions to take. Using Roman numerals for packing groups ensures a standardized approach that is universally understood in the transportation and handling of hazardous materials, enhancing safety and compliance across various sectors.
