According to OSHA regulations, which cleaning method for blood spills is NOT acceptable?

The reason that using household bleach at a 1:10 v/v dilution is not acceptable according to OSHA regulations is primarily due to its effectiveness and safety concerns in a professional setting. While bleach does have disinfecting properties, it can be unstable in diluted form, especially in the presence of organic matter, which can render it less effective against pathogens commonly found in blood spills. Additionally, bleach can produce harmful fumes and may react with other substances, leading to safety hazards for staff.

In comparison, the other options listed provide a more reliable and safer approach to blood spill management. EPA-List D, E, and B disinfectants are specifically rated for efficacy against bloodborne pathogens and are designed for use in healthcare settings, ensuring compliance with OSHA standards for infection control. These disinfectants have undergone testing for effectiveness and are formulated for safety, making them suitable for routine cleaning and disinfection practices in environments where blood exposure may occur. Thus, option A is deemed unacceptable under OSHA because it does not align with the recommended standards for safety and effectiveness in managing blood spills.
