Question 1

What is the difference between disinfection and sterilization?

Accepted Answer

Disinfection destroys most microorganisms on non-living surfaces but does not kill bacterial spores. Sterilization destroys ALL microorganisms, including spores, on surfaces and instruments.

Question 2

Which level of decontamination is required for non-critical reusable esthetics tools that contact intact skin?

Accepted Answer

Low-level disinfection is required for non-critical items that contact only intact skin, as they pose minimal risk of infection transmission.

Question 3

What is the required contact time for most EPA-registered hospital-grade disinfectants used on esthetic implements?

Accepted Answer

Most EPA-registered hospital-grade disinfectants require a 10-minute contact time to be effective, meaning tools must remain fully submerged or wet for the full duration.

Question 4

What type of disinfectant is commonly used in salons and is effective against bacteria, viruses, and fungi when used at the correct concentration?

Accepted Answer

Quaternary ammonium compounds (quats) are commonly used salon disinfectants that are effective against bacteria, viruses, and fungi at proper concentrations and are non-corrosive to most implements.

Question 5

Before placing an implement into a disinfectant solution, what must be done first?

Accepted Answer

The implement must first be cleaned (scrubbed with soap and water) to remove all visible debris, as organic matter can inactivate disinfectants and prevent proper efficacy.
