What is defined as hazardous material?

Hazardous material is specifically defined as materials that pose an unreasonable hazard to health, safety, and property. This definition emphasizes the risk these materials can present in various contexts, whether it be during transportation, storage, or disposal. Hazardous materials can include a wide range of substances, including chemicals that are toxic, flammable, corrosive, or reactive.

Other options, while they may reference certain materials or categories, do not accurately define what constitutes hazardous material. Items that can be easily disposed of do not inherently pose a risk, and common household products can vary widely in their safety and hazards. Non-toxic industrial materials, by definition, do not present the risks associated with hazardous materials. Thus, the correct answer focuses on the inherent danger posed by certain substances, which is a crucial aspect of managing and handling hazardous materials safely.
