Which category includes items such as blood bags and urine containers?

The correct choice is infectious waste, as this category specifically pertains to waste that poses an infection risk to humans, including various biohazardous materials. Items like blood bags and urine containers fall under this classification because they may contain pathogens, bodily fluids, or other materials that can transmit infectious diseases.

Infectious waste is meticulously regulated due to the potential health hazards it presents. Proper disposal methods are crucial to prevent contamination and protect public health. Blood bags often hold blood products that can be infectious if not handled correctly, while urine containers can likewise carry pathogens from infectious diseases. Both components require specific handling, treatment, and disposal protocols to ensure safety and compliance with health regulations.

The other categories—chemical, pharmaceutical, and radioactive waste—do not accurately describe the risks associated with blood bags and urine containers, as they focus on different aspects of waste management.
