A blood and body fluid cleanup and disinfection chlorine bleach solution is also called:

• A. 5% bleach solution
• B. 15% bleach solution
• C. 2% bleach solution
• D. 10% bleach solution

Answer: (D)

Disinfecting surfaces that have come into contact with blood or body fluids requires a chlorine bleach solution at a strength that reliably inactivates pathogens. The standard practice is to use the stronger dilution of household bleach for cleanup, because it provides enough active chlorine to kill a broad range of organisms that could be present in the fluids. We choose this level of disinfection to balance effectiveness with safety and practicality; weaker dilutions may fail to disinfect, while overly strong solutions can be unnecessarily corrosive and hazardous. Therefore, among common options, the stronger dilution is the best match for proper decontamination of blood and body fluids. Always prepare the solution and use appropriate PPE according to guidelines.
