Which type of waste is specifically dangerous because it can transmit an infectious disease?

• A. Infectious Waste
• B. Nonhazardous Waste
• C. Chemical Waste
• D. Radioactive Waste

Answer: (A)

The danger here comes from waste that carries pathogens capable of causing disease. When waste is contaminated with illness-causing microbes, it can transmit infections if people touch it, breathe dust, or contact contaminated surfaces. That’s why this type of waste is treated to inactivate the pathogens before disposal, and handled with strict precautions—biohazard bags, red containers, clear labeling, and methods like autoclaving or incineration to destroy any remaining microorganisms.

Other wastes pose different risks. Nonhazardous waste isn’t associated with disease transmission. Chemical waste is dangerous mainly because of toxic, corrosive, or reactive chemicals. Radioactive waste is hazardous due to radiation exposure. But only infectious waste is specifically dangerous because it can transmit an infectious disease.
