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 that can be dangerous if not handled correctly. Such materials can cause harm through various means, including toxicity, flammability, reactivity, and environmental impact.

For instance, chemicals like asbestos, certain industrial solvents, and radioactive materials fall under this category due to their potential to cause health issues or environmental damage. Proper training, labeling, and handling protocols are essential when working with hazardous materials to ensure safety for individuals and the surroundings.

The other options do not accurately capture the nature of hazardous materials. A substance that is easy to handle does not necessarily mean it is safe; likewise, a non-toxic substance is not considered hazardous as it does not pose any risk. Common household items can vary significantly, and not all of them are hazardous; however, some may possess hazardous qualities depending on their chemical composition and usage.
