Final answer:
Contaminated wipes from a blood spill should be placed in a biohazard waste container and sterilized before disposal, according to strict biosafety practices.
Step-by-step explanation:
When disposing of contaminated wipes from a blood spill, the wipes should be placed in a biohazard waste container. It's important to recognize the international symbol for biohazards to ensure proper disposal. Following biosafety practices, contaminated wipes should never be disposed of with regular garbage due to the potential for infection spread. Moreover, health and safety guidelines require that all biohazard waste must be sterilized, usually by an autoclave, before it can be disposed of in the waste stream to prevent contamination and ensure safe handling.
