Question 1

What is the key difference between sterilization and disinfection in a salon setting?

Accepted Answer

Sterilization destroys ALL microorganisms including bacterial spores using an autoclave (250°F, 15 psi, 20 min), while disinfection kills most pathogens but does NOT eliminate bacterial spores.

Question 2

Which level of decontamination does washing tools with soap and water represent, and why is it insufficient alone for reusable salon implements?

Accepted Answer

Soap and water represents sanitation, the lowest level of decontamination. It only reduces the microbial count to a safe level but does not kill enough pathogens to make tools safe for reuse on the next client.

Question 3

What are the three correct sequential steps for decontaminating reusable implements after a salon service?

Accepted Answer

The correct sequence is: (1) Clean by removing all visible debris with soap and water, (2) Disinfect by fully immersing in an EPA-registered solution, then (3) Store in a clean, closed container until next use.

Question 4

Why must all visible debris be removed from implements BEFORE placing them into disinfectant solution?

Accepted Answer

Organic matter such as hair, skin oils, and blood can chemically inactivate the disinfectant solution, preventing it from making direct contact with the tool surface and killing pathogens effectively.

Question 5

Which regulatory agency registers and approves the disinfectant products that cosmetologists must use on salon implements?

Accepted Answer

The EPA (Environmental Protection Agency) registers and approves disinfectant products. Salons must use EPA-registered, hospital-grade disinfectants to ensure the products are proven effective against targeted pathogens.
