All implements that have come in contact with blood or bodily fluids must be disinfected by complete immersion in which disinfectant?

• A. An EPA registered, tuberculocidal disinfectant
• B. A household bleach solution
• C. Rubbing alcohol
• D. Soap and water only

Answer: (A)

The key concept is using a disinfectant that is proven to kill a broad range of pathogens, including those in blood and bodily fluids. Implements that have come into contact with blood or bodily fluids must be completely immersed in an EPA-registered tuberculocidal disinfectant so every surface stays in contact for the product’s required dwell time. This level of disinfection is necessary because bloodborne pathogens can be present on tools, and tuberculocidal products are specifically tested to kill tougher organisms like Mycobacterium tuberculosis, providing reliable protection against cross-contamination.

Rubbing alcohol evaporates quickly and does not provide the sustained contact required to fully disinfect multi-use implements. Soap and water cleans surfaces but does not achieve disinfection. Household bleach solutions can be effective in some cases if they are properly prepared and labeled for disinfection, but they are not universally tuberculocidal and may be corrosive to tools; therefore, the standard requirement emphasizes an EPA-registered tuberculocidal disinfectant to ensure consistent, proven effectiveness.
