Hazardous materials are defined as substances that pose a threat to which of the following?

• A. Substances that are only hazardous to water quality.
• B. Materials used in medical devices.
• C. Substances that pose a threat to health, safety, or the environment.
• D. Anything that is stored in a hospital.

Answer: (C)

Hazardous materials are substances that can cause harm to health, safety, or the environment. The defining idea is the potential for adverse effects on people, property, and ecological systems, not just a single domain like water quality. Because of this, the description that fits best is substances that pose a threat to health, safety, or the environment. These materials can be chemicals, fuels, toxins, corrosives, or other agents that could injure someone, ignite or explode, or contaminate air, water, or soil. The other options are too narrow: water quality alone isn’t the full scope, not all materials used in medical devices are hazardous, and not everything stored in a hospital is necessarily hazardous.
