California Cosmetology Written ExamSafety and Infection ControlMedium
An inspector explains to a new cosmetologist that before any implement can be disinfected with an EPA-registered disinfectant, it must first go through an earlier decontamination step to remove visible debris, oils, and hair. Which level of decontamination is this?
- ASterilization
- BFumigation
- CSanitation (cleaning)
- DUV exposure
Show answer & explanationAnswer & explanation
Correct answer: C. Sanitation (cleaning)
Sanitation (cleaning with soap/water or an appropriate cleaner) is the first and lowest level of decontamination, physically removing debris and oils so disinfectant can properly contact the implement surface. Disinfection and sterilization are higher levels that must follow proper cleaning.
Why the other options are wrong
- A. Sterilization is the highest level, destroying all microbial life, and is not required or achievable in most California salons.
- B. Fumigation is not a recognized decontamination level in salon regulation.
- D. UV light alone is not an acceptable substitute for proper cleaning or disinfection.
Levels of Decontamination
A three-tier system: sanitation (cleaning), disinfection, and sterilization, each representing an increasing degree of pathogen removal.
- Cleaning must occur before disinfecting
- Disinfection kills most pathogens on surfaces
- Sterilization destroys all life, not required in CA salons
Memory trick: Clean, then Disinfect, then Sterilize — CDS, like steps on a ladder.
