What is the recommended solution for cleaning blood spills?

The recommended solution for cleaning blood spills is a 1:10 dilution of bleach. This concentration is effective because it provides a sufficient level of sodium hypochlorite, which is a strong disinfectant capable of inactivating a broad range of pathogens including viruses, bacteria, and fungi. The 1:10 bleach solution is considered an appropriate balance that maximizes disinfecting properties while minimizing risks associated with the corrosive nature of undiluted bleach.

Using this solution ensures that any bloodborne pathogens present in the spill are effectively neutralized, adhering to safety protocols established in healthcare and laboratory settings. The dilution is critical, as undiluted bleach can be too harsh on surfaces and may release harmful fumes, presenting safety concerns for those administering the cleaning.

Other options may have their disinfecting properties but are not typically recommended for routine cleaning of blood spills in the same way. Hydrogen peroxide is often used for disinfecting surfaces but may not be as effective against all bloodborne pathogens at low concentrations. Peracetic acid is primarily used for sterilization and may not be readily available for general cleaning purposes. Glutaraldehyde, while a potent disinfectant, is generally used for the high-level disinfection of medical equipment rather than surface cleaning.
