Which option is NOT classified as a Hazardous Material?

Air pollution is not classified as a hazardous material in the same sense as the other listed items. Hazardous materials typically include specific substances that can pose significant risks to health, safety, or the environment when handled improperly.

Explosives, corrosive substances, and toxic chemicals are all defined as hazardous materials due to their potential to cause harm through chemical reactions, toxicity, or dangerous physical properties. They are regulated under various safety and environmental laws because of the direct dangers they pose in specific quantities and contexts.

Air pollution, on the other hand, is more of an environmental issue that arises from the release of pollutants into the atmosphere, affecting air quality and public health but not fitting the precise criteria of a hazardous material as defined by regulation. Therefore, the classification of air pollution differs fundamentally from the other substances, which are tangible, defined materials that can be handled and transported.
