Which of the following is NOT considered a dangerous characteristic of hazardous waste?

Stability is considered the correct answer because it is not classified as a dangerous characteristic of hazardous waste. The primary dangerous characteristics of hazardous waste recognized by environmental regulations typically include ignitability, corrosivity, and toxicity.

Ignitability refers to the waste’s ability to catch fire easily, presenting a fire hazard. Corrosivity involves the ability of waste to corrode materials or living tissue, posing risks to both individuals and the environment. Toxicity describes the adverse effects that a waste can have on human health or the environment, especially if it leaches harmful substances into water or soil.

In contrast, stability refers to the ability of a substance to remain unchanged under varying conditions. While stability can be a factor in assessing the overall risk of certain substances, it does not inherently present a danger in the same way as the other three characteristics do. Therefore, stability is not categorized as a dangerous characteristic of hazardous waste.
