Which of the following is NOT a characteristic of hazardous materials?

• A. Flammability
• B. Toxicity
• C. Inertness
• D. Corrosiveness

Answer: (C)

Inertness is the characteristic that does not apply to hazardous materials. Specifically, hazardous materials are substances that can pose significant risks to health, safety, and the environment due to their chemical properties. Flammability, toxicity, and corrosiveness are all traits that indicate a hazardous material's potential for harm.

Flammability refers to the ability of a substance to ignite and burn easily, which poses fire risks. Toxicity indicates how harmful a substance can be to living organisms, potentially causing illness or death. Corrosiveness describes the capacity of a material to damage or destroy living tissue or material surfaces upon contact.

In contrast, inertness signifies a lack of reactivity; inert substances do not readily undergo chemical change or react with other substances. This means they do not pose the same level of risk as hazardous materials, which is why inertness is the correct choice for what does not characterize hazardous materials.
