What does the term "Infectious Substances" refer to in hazardous materials?

The term "Infectious Substances" specifically refers to materials that contain pathogens capable of causing diseases in humans or animals. This encompasses a range of biological agents, including bacteria, viruses, fungi, and parasites. Understanding this definition is crucial for safely handling, transporting, and disposing of such substances, as they pose significant health risks if not managed correctly.

Pathogens are microscopic organisms that can lead to infectious disorders, which might be transmitted through contact, inhalation, or ingestion. This understanding highlights the importance of stringent regulations and training when dealing with these types of hazardous materials.

The other choices, while related to hazardous materials, address completely different categories. Flammable substances are those that can ignite easily, explosives refer to materials that can detonate under certain conditions, and environmental pollutants focus on contaminants affecting ecosystems rather than pathogens. Recognizing the specific nature of infectious substances is vital in the context of health and safety regulations in the transport and handling of hazardous materials.
