ABA Sanitation & Disinfection Protocols 2 — Questions and Answers
Question 1: Which EPA registration category must a disinfectant carry to be legally used on barbering tools in a licensed shop?
- EPA-registered hospital-grade disinfectant (Correct answer)
- FDA-approved antiseptic
- OSHA-certified sterilant
- USDA-certified sanitizer
Correct answer: EPA-registered hospital-grade disinfectant
State barber boards require EPA-registered hospital-grade disinfectants to ensure proven efficacy against pathogens found in professional settings.
Question 2: After clipping a client with an open wound, what is the FIRST action a barber should take before continuing service?
- Stop service, put on gloves, and properly discard any contaminated materials (Correct answer)
- Apply alcohol directly to all tools and resume immediately
- Rinse tools under hot water and continue
- Spray the wound with disinfectant spray
Correct answer: Stop service, put on gloves, and properly discard any contaminated materials
Exposure to blood requires immediate cessation of service, use of PPE, and proper disposal of contaminated items per infection-control standards.
Question 3: What is the minimum contact time most EPA-registered barbicide-type disinfectants require to kill HIV and HBV on implements?
- 10 minutes (Correct answer)
- 30 seconds
- 5 minutes
- 1 minute
Correct answer: 10 minutes
Barbicide and similar quaternary ammonium / phenolic disinfectants typically require 10 minutes of full immersion contact time to achieve efficacy against HIV and HBV.
Question 4: A barber's multi-use straight razor must be disinfected by:
- Full immersion in an EPA-registered disinfectant solution (Correct answer)
- Wiping the blade with an alcohol pad between clients
- Rinsing under running hot water
- Placing in a UV sanitizing box for 30 seconds
Correct answer: Full immersion in an EPA-registered disinfectant solution
Multi-use implements with potential blood contact must be fully immersed in an EPA-registered disinfectant — surface wiping is insufficient.
Question 5: Which of the following items CANNOT be disinfected and must be discarded after a single use?
- Disposable neck strips (Correct answer)
- Stainless steel shears
- Glass disinfectant jars
- Metal combs
Correct answer: Disposable neck strips
Porous or single-use items like neck strips cannot be disinfected and must be discarded after each client to prevent cross-contamination.
Question 6: Wet sanitizers (disinfectant jars) must be covered when not in use primarily to:
- Prevent contamination and slow evaporation of the solution (Correct answer)
- Keep the implements warm
- Comply with fire codes
- Prevent metal implements from rusting
Correct answer: Prevent contamination and slow evaporation of the solution
Covering disinfectant jars prevents airborne debris from contaminating the solution and reduces evaporation, maintaining effective concentration.
Question 7: Under standard infection-control rules, how often must disinfectant solution in a wet sanitizer be changed?
- Daily or when visibly contaminated or diluted (Correct answer)
- Once per week
- Once per month
- Only when it changes color
Correct answer: Daily or when visibly contaminated or diluted
Solution must be changed at least daily and immediately whenever it becomes visibly dirty, diluted, or contaminated to maintain effective disinfection.
