Final answer:
Carbon steel is not considered a hazardous material unless it contains or is coated with hazardous substances, unlike oil, batteries, and some scrap metals which can be inherently hazardous. Therefore correct option is D
Step-by-step explanation:
The item listed that is NOT an example of a hazardous material is D. Carbon Steel. Hazardous materials are those that can be harmful when ingested or absorbed, and often include toxic waste, which can be reactive, ignitable, and corrosive. Common examples of hazardous materials include oil, due to its environmental impact; batteries, which may contain acids or heavy metals; and in some cases, certain types of scrap metal, which can be hazardous due to residual chemicals or heavy metal content. However, carbon steel, while it can pose certain risks if not handled correctly, is generally not classified as a hazardous material unless it is coated with or contains hazardous substances.
