Illinois Nail Technician Practice Exam

Which of the following is NOT a level of decontamination?

1. Sanitation

2. Sterilization

3. Filtration

4. Disinfection

The correct answer is: Filtration

Filtration is not considered a level of decontamination in the context of nail technology and other beauty services. The three primary levels of decontamination are sanitation, disinfection, and sterilization. Sanitation refers to the process of reducing the number of microorganisms to a safe level, often through cleaning and using specific chemicals. Disinfection involves eliminating most bacteria, viruses, and fungi on surfaces, but it may not destroy all microbial forms. Sterilization is the most thorough level, which destroys all forms of microbial life, including spores. Filtration, while it can be used to purify liquids and air by removing particles and microorganisms, is not classified as a decontamination level within the context of personal care services. It is more of a physical process rather than a method of sanitation, disinfection, or sterilization. Understanding the definitions and applications of these levels is crucial for maintaining a safe and hygienic environment in the salon.
