Certified Healthcare Safety Professional (CHSP) Practice Exam

Infectious substances are specifically defined as materials that contain pathogens, which are microorganisms capable of causing disease in humans, animals, or plants. These pathogens include bacteria, viruses, fungi, and parasites. Understanding this is crucial in healthcare settings, where the handling and disposal of infectious waste are governed by strict safety protocols to prevent the spread of disease.

While chemicals, heavy metals, and radioactive materials are important categories of hazardous materials, they do not encompass the specific definition of infectious substances. The focus on pathogens highlights the unique risks associated with biological hazards, distinguishing them from other types of hazardous materials that may pose different safety concerns. This distinction is vital in ensuring proper identification, handling, and management of infectious substances in the context of healthcare and safety practices.
