Texas Class A Barber Written ExamSanitation, Disinfection, and SafetyMedium
A barber is preparing to clean and disinfect their clippers after a service. The clippers are non-porous and have been used on a client with no visible cuts or signs of infection. Which of the following levels of decontamination is MOST appropriate for these clippers?
- ASanitization
- BDisinfection
- CAntisepsis
- DSterilization
Show answer & explanationAnswer & explanation
Correct answer: B. Disinfection
Disinfection is the appropriate level of decontamination for non-porous tools that come into contact with intact skin. It kills most harmful bacteria, fungi, and viruses, but not bacterial spores, which is sufficient for this scenario.
Why the other options are wrong
- A. Sanitization is the lowest level, primarily for reducing the number of microbes to a safe level, often for general public health, not enough for barber tools.
- C. Antisepsis refers to reducing microbes on living tissue, not on inanimate objects like clippers.
- D. Sterilization is too high a level for clippers used on intact skin; it kills all microbial life, including spores, typically for invasive procedures.
Levels of Decontamination
A hierarchy of processes (sanitization, disinfection, sterilization) used to reduce or eliminate microorganisms from surfaces or objects, each with specific applications and efficacy.
- Sterilization: Kills all microbes, including spores.
- Disinfection: Kills most microbes, not spores.
- Sanitization: Reduces microbes to safe levels.
