Which label must be present for the disposal of biohazardous waste?

The requirement for labeling biohazardous waste focuses on ensuring safety and clear identification of dangerous materials. The presence of the word "Biohazard" in bold black letters on a red background is a standardized universal indicator that alerts individuals to the potential risk of contamination or exposure to infectious substances. This labeling system is crucial in healthcare and laboratory environments, as it helps to prevent accidental exposure, ensures proper handling and disposal, and complies with regulations designed to protect public health and safety.

Other choices might reference labels for different types of waste, but they do not convey the specific hazards associated with biohazardous materials. The unique combination of color and wording used for biohazard waste is essential for immediate recognition and response in potentially hazardous situations.
