Which of the following materials is generally not considered hazardous?

Fresh produce is generally not considered hazardous material because it does not pose significant risks to human health or the environment under normal conditions. In fact, fresh produce is typically safe for consumption and is governed by food safety regulations rather than hazardous materials guidelines.

Contrarily, corrosive liquids, radioactive substances, and waste oil fall under various hazardous material classifications due to their properties. Corrosive liquids can cause injury or severe damage to skin, eyes, and other tissues upon contact. Radioactive substances emit radiation that can be harmful to living organisms and require specific handling, packaging, and transportation regulations. Waste oil is often categorized as hazardous due to the potential environmental risks it poses, especially if it contains contaminants or is improperly disposed of. These materials are subject to strict regulations to protect public health and the environment, making fresh produce a clear exception.
