What does it mean for a material to be classified as "non-hazardous"?

A material classified as "non-hazardous" means that it poses no significant risk to health or the environment under normal conditions. This classification indicates that, during typical handling and use, the material is unlikely to cause harm to people, wildlife, or the ecosystem. Non-hazardous materials are generally recognized as safe from significant physical or chemical hazards, which means they do not present dangers such as toxicity, flammability, or reactivity that could result in harmful incidents.

In this context, while other options may seem plausible, they don't accurately encompass the full meaning of "non-hazardous." For example, while a non-hazardous material may be relatively safe for use (addressing the notion of minimal risks), it doesn't mean it can be classified as completely safe for any use in all situations. Similarly, while some non-hazardous materials can indeed be thrown into general landfills, this is not a definitive characteristic of all such materials. Non-hazardous status does not inherently imply that no precautions are necessary during handling; some level of care is usually still required to ensure safety and compliance with applicable regulations.
