Which ratio is used for bodily fluid cleanup with water to bleach?

• A. 1:5
• B. 1:10
• C. 1:1
• D. 1:20

Answer: (B)

Disinfection of bodily fluids relies on using a properly diluted bleach solution that is strong enough to kill pathogens but safe for handling and surfaces. The best-dressed dilution is the one that health guidelines recommend for cleanups of body fluids: it provides enough potency to inactivate viruses and bacteria present, while reducing risks from fumes, skin irritation, and surface damage that come with undiluted or overly strong solutions. This balance is what makes that particular ratio the right choice. When using it, wear gloves, prepare a fresh solution, apply it to the spill, and let it remain moist for the recommended contact time before wiping or rinsing. Avoid mixing bleach with ammonia or acids, and follow safety and disposal guidelines.
