What does proper disposal of biohazardous waste help to prevent?

The correct choice highlights that proper disposal of biohazardous waste is crucial in preventing both infections and environmental harm. Biohazardous waste includes any materials that may be infectious, toxic, or hazardous to the health of humans or the environment, such as medical waste, sharps, and other materials potentially containing pathogens.

When biohazardous waste is not disposed of correctly, there is a significant risk of spreading infections, particularly in healthcare settings where the vulnerable populations may come into contact with contaminated materials. By ensuring that this waste is managed properly—using appropriate containers and disposal methods—facilities can minimize the risk of exposure to dangerous pathogens, thereby protecting both individuals and the larger community.

Additionally, improper disposal can lead to environmental harm, such as soil and water contamination, which can have far-reaching effects on ecosystems and human health. Safe disposal practices ensure that hazardous materials do not leach into the ground or water supply, reducing the risk of environmental contamination and its associated health risks. Thus, the correct answer underscores the dual benefits of ensuring safety for both people and the environment through proper biohazardous waste management.
