Hazard Class Definitions do NOT Require Group Designations?

Hazard Class Definitions do NOT Require Group Designations?

• A. Class 3 and 4
• B. Classes 2 & 7
• C. Class 6 only
• D. All Hazards require groups

Answer: (B)

Grouping designations, or packing groups, express how severe the hazard is for many hazardous materials and guide packaging and shipping requirements. Not every hazard class uses a packing group in its definitions. For gases (Class 2) and radioactive materials (Class 7), there is no packing group designation to include in their hazard class definitions. That’s why these two classes do not require a group designation. In contrast, many other classes do use packing groups (for example, Class 3 flammable liquids and Class 6 toxic substances) to indicate the level of hazard and to tailor packaging and handling rules accordingly. So the statement is true because gases and radioactive materials don’t rely on packing groups in their hazard class definitions.
