Which of the following is not a characteristic of hazardous waste?

The correct choice, which identifies a characteristic that is not associated with hazardous waste, is based on an understanding of the definitions and regulatory frameworks surrounding hazardous waste.

Ignitability, corrosivity, and reactivity are all properties that can classify a substance as hazardous waste under regulations such as those outlined by the Environmental Protection Agency (EPA).

• Ignitability refers to the waste’s ability to catch fire easily, thereby posing a fire risk. Substances that can ignite under normal conditions are considered hazardous due to their potential to cause fires or explosions.

• Corrosivity is a characteristic of substances that can corrode metals or cause chemical burns to human skin. This property is significant in determining whether a waste product can damage the environment or human health upon contact or disposal.

• Reactivity refers to the tendency of a substance to chemically react with other materials, which can create hazardous conditions, including exploding or generating toxic gases.

Combustibility, while it may sound similar to ignitability, does not directly relate to the regulatory definition of hazardous waste. Not all combustible materials meet the strict criteria set for ignitability within hazardous waste classifications. Therefore, the term 'combustibility' lacks the specific regulatory definition and implications that define hazardous waste compared to the
