Which of the following is considered a hazardous material?

A hazardous material is defined as any substance that poses a risk to health, safety, property, or the environment. This definition encompasses a wide range of materials, including chemicals, biological agents, radiological materials, and any other substance that can potentially cause harm. The key point is that the classification of a material as hazardous is based on its potential effects rather than its physical state or origin.

The other options narrow the focus to specific categories that do not fully capture the broad nature of hazardous materials. For example, non-toxic items are, by definition, not hazardous because they do not pose a risk. Limiting the definition to household cleaning products excludes many other significant types of hazardous materials found in industrial settings, pharmaceuticals, or agricultural applications. Likewise, food items generally do not fall under this classification unless they are contaminated or improperly stored, which would then pose a risk to health. Therefore, the inclusive nature of the correct choice emphasizes the importance of recognizing various substances that could harm individuals or the environment.
