Sample Questions

Question 1

What must be done to an implement BEFORE it is placed into a disinfectant solution?

Answer: Implements must first be cleaned (scrubbed with soap and water or a brush) to remove all visible debris, because organic matter deactivates disinfectants.

Question 2

Which level of disinfectant is required for non-porous salon tools that contact intact skin?

Answer: Hospital-grade (EPA-registered) disinfectants with bactericidal, fungicidal, and virucidal claims are required for non-porous tools used on intact skin.

Question 3

What is the correct dilution ratio for a bleach (sodium hypochlorite) disinfectant solution used in nail salons?

Answer: A 1:10 ratio (1 part bleach to 9 parts water), which yields approximately a 5,000 ppm solution, is the standard disinfecting concentration.

Question 4

How long must implements typically be fully immersed in an EPA-registered disinfectant to be properly disinfected?

Answer: Implements must be fully immersed for the time specified on the disinfectant label, typically 10 minutes, to achieve proper disinfection.

Question 5

What is the difference between disinfection and sterilization?

Answer: Disinfection destroys most harmful microorganisms on non-living surfaces but does not kill all spores. Sterilization destroys ALL microbial life, including spores.
