Question 1

What are the three levels of decontamination used in cosmetology, listed from lowest to highest level of microbial destruction?

Accepted Answer

Sanitation (lowest), disinfection (middle), and sterilization (highest). Each level destroys a progressively greater number and type of microorganisms.

Question 2

What does sanitation accomplish in a cosmetology setting?

Accepted Answer

Sanitation significantly reduces the number of pathogens on a surface but does not kill all microorganisms. It is the lowest level of decontamination.

Question 3

Which level of decontamination is required for tools and implements used in New York cosmetology salons on intact skin?

Accepted Answer

Disinfection is required for tools used on intact skin. It destroys most harmful microorganisms but not necessarily all spores.

Question 4

What is sterilization and why is it not routinely required in cosmetology salons?

Accepted Answer

Sterilization destroys all microbial life including spores. It is not routinely required in salons because cosmetology tools typically do not penetrate the skin, making disinfection sufficient.

Question 5

What type of disinfectant is most commonly used in New York cosmetology salons to disinfect non-porous implements?

Accepted Answer

EPA-registered, hospital-grade disinfectants are most commonly used. They must be effective against bacteria, fungi, and viruses including HIV and hepatitis B.
