A ______ bleach solution is used to disinfect a large spill greater than ______.

• A. A 1:50 bleach solution is used to disinfect a large spill greater than 100 ml
• B. A 1:100 bleach solution is used to disinfect a large spill greater than 10 ml
• C. A 1:10 bleach solution is used to disinfect a large spill greater than 10 ml
• D. A 1:1000 bleach solution is used to disinfect a large spill greater than 50 ml

Answer: (C)

Disinfection of spills involving blood or bodily fluids depends on how large the spill is. The bigger the spill, the more concentrated the bleach needs to be to ensure pathogens are effectively inactivated. Using a stronger bleach dilution for a large spill provides sufficient disinfecting power to reduce the risk to staff and others. Weaker dilutions are designed for smaller spills and would not reliably disinfect a larger amount of contaminated material. So for a spill deemed large, go with the stronger dilution and keep the solution in contact with the surface for an appropriate amount of time to achieve disinfection. Remember to wear appropriate PPE, follow proper cleanup procedure, and avoid mixing bleach with other cleaners.
