Which of the following is NOT typically a characteristic of hazardous waste?

Inertness is the correct answer because it describes materials that do not chemically react with other substances, meaning they are generally stable and non-hazardous. Inert materials do not exhibit harmful effects such as corrosion, reactivity, or toxicity, which are common characteristics of hazardous waste.

On the other hand, corrosivity refers to the ability of a substance to corrode metal or tissue, making it potentially dangerous if not handled properly. Reactivity indicates that a waste can undergo chemical reactions, possibly leading to explosive or toxic situations when mixed with other substances. Toxicity signifies that a waste can harm living organisms, either through direct exposure or by leaching harmful substances into the environment. These three characteristics—corrosivity, reactivity, and toxicity—are critical in identifying hazardous waste, while inertness represents the lack of hazardous properties.
