A substance categorized as flammable gas is placed in which division?
Correct Answer:
Gas Division 2.1
Explanation:
Gases are organized into Class 2, with divisions that reflect their specific hazards. A gas that is flammable is placed in Division 2.1, which is the category for flammable gases. The other gas divisions cover different hazards: 2.2 is for non-flammable, non-toxic gases, and 2.3 is for toxic gases. So the defining trait here is SAMPLEflammability, which places the substance in the flammable gas division, 2.1. This classification matters for packing, labeling, and handling requirements. Explosives belong to a different class and follow separate rules, not the gas divisions.
