Which of the following is considered a biohazard?

The correct choice reflects a scenario that poses a significant risk to health and safety due to the potential exposure to infectious materials. The act of splashing blood when a cap is removed represents a direct exposure to biohazardous material, which includes any biological substance that can pose a threat to human health or the environment.

Blood is classified as a biohazard because it can carry pathogens that are capable of transmitting diseases, such as HIV, Hepatitis B, and Hepatitis C. In healthcare settings, it is crucial to handle blood and other bodily fluids with strict protocols to minimize the risk of infection and ensure safety for all personnel and patients.

In contrast, the other options involve practices that either do not involve hazardous materials or do not pose a risk of infection. Waste disposal of non-contaminated materials does not involve biohazardous substances and therefore doesn’t present a biohazard risk. Scrapping old documents relates to maintaining confidentiality and data security rather than biohazard concerns. Disinfecting surfaces is a necessary practice for infection control but does not itself involve the handling of biohazardous materials unless those surfaces contain such substances. Thus, the correct choice highlights a specific instance of handling biohazardous material, underscoring the
