What is NOT a characteristic of hazardous waste?

A characteristic of hazardous waste is that it poses potential dangers to human health or the environment. The properties that define hazardous waste typically include ignitable, corrosive, toxic, and reactive traits. These characteristics represent various ways in which waste can be harmful:

• Ignitable waste can easily catch fire and sustain combustion.
• Corrosive waste can corrode materials or living tissue, posing risks of chemical burns or damage.
• Toxic waste can cause harmful effects upon exposure or ingestion, either acutely or chronically.

In contrast, the term "innocuous" refers to something that is harmless or does not pose any risk. Thus, classifying waste as innocuous would mean it does not meet the criteria for hazardous waste, which inherently includes potential risks and dangers. This distinction makes "innocuous" the correct choice as it is not a characteristic of hazardous waste.
