Which hazard classification is associated with anhydrous ammonia for its corrosive properties on international routes?

Anhydrous ammonia is classified as a hazardous material due to its properties and potential risks associated with its transport, particularly relating to its corrosive nature. In the context of international transportation, the classification systems delineate specific categories based on the inherent dangers posed by substances.

The correct classification associated with anhydrous ammonia is primarily noted under the corrosive materials category, which is classified as Class 8. This classification indicates that the substance can cause severe damage to living tissue as well as material damage upon contact, which is significant for safety during transport and handling.

Additionally, anhydrous ammonia exhibits properties that classify it under other hazard classes, such as toxic properties (which falls under Class 2.3, as a toxic gas) and its potential to be a non-flammable gas (Class 2.2). The comprehensive nature of the classification highlights the various risks that anhydrous ammonia poses in different scenarios and environments, reinforcing its status as a multi-faceted hazard.

Thus, by selecting all classifications that apply to anhydrous ammonia, the answer captures the full scope of its hazards, particularly emphasizing the corrosive nature that is critical for safety precautions and regulatory compliance in transportation.
