Question 1

What is the correct order of the three levels of decontamination used in a nail salon, from lowest to highest?

Accepted Answer

The three levels are sanitation (soap and water to reduce pathogens), disinfection (EPA-registered chemical to kill most pathogens on surfaces), and sterilization (autoclave to destroy all microbial life).

Question 2

Which level of decontamination is legally required for reusable metal nail implements such as nippers and cuticle pushers between clients?

Accepted Answer

Disinfection is required — metal implements must be cleaned of all debris first, then fully immersed in an EPA-registered hospital-grade disinfectant that is bactericidal, virucidal, and fungicidal.

Question 3

Why is an autoclave NOT required for standard nail salon implements like nippers and metal files?

Accepted Answer

Autoclaves are required only for implements that pierce or break the skin, such as surgical tools; standard nail implements do not penetrate tissue, so disinfection with an EPA-registered chemical is the legally required and sufficient standard.

Question 4

What is the difference between the eponychium and the true cuticle, and why does this distinction matter for infection control?

Accepted Answer

The eponychium is living skin at the nail base and should not be cut aggressively because cutting living tissue creates open wounds that allow bacteria to enter; the true cuticle is dead, colorless tissue on the nail plate that can be safely and gently removed.

Question 5

Which specific characteristics must an EPA-registered disinfectant have to be considered appropriate for use on salon implements?

Accepted Answer

The disinfectant must be hospital-grade and labeled as bactericidal (kills bacteria), virucidal (kills viruses), and fungicidal (kills fungi) to address the full range of pathogens encountered in a professional nail salon environment.
