Which statement best describes cleaning in the postrun phase?

• A. Killing pathogens with disinfectants.
• B. Disinfection.
• C. Removal of debris.
• D. Sterilization.

Answer: (C)

Cleaning in the postrun phase means physically removing dirt, organic matter, and other debris from equipment and surfaces. This step reduces bioburden and prepares items for the next steps, because disinfectants and sterilants work best when surfaces are clean. In EMS practice, cleaning is not about killing pathogens; it’s about washing away soil so subsequent disinfection or sterilization can be effective. Disinfection reduces pathogen numbers, and sterilization aims to eliminate all microbial life, but neither replaces the need to remove debris first. Therefore, removal of debris best describes cleaning.
