Under California Code of Regulations Title 16, Division 9, what must a cosmetologist do with metal tweezers immediately after using them on a client?

  1. ARinse them under hot running water for at least 10 seconds
  2. BClean them and completely immerse them in an EPA-registered, hospital-grade disinfectant for the full required contact time
  3. CWipe them with a dry paper towel and place them back in the tray for the next client
  4. DWrap them in a clean towel and disinfect them once at the end of the business day
Show answer & explanation

Correct answer: B. Clean them and completely immerse them in an EPA-registered, hospital-grade disinfectant for the full required contact time

California regulations require all non-porous multi-use implements, including metal tweezers, to be cleaned of debris and then completely immersed in an EPA-registered, hospital-grade (bactericidal, fungicidal, and virucidal) disinfectant for the manufacturer's specified contact time after each use on a client. Wiping, rinsing, or delaying disinfection does not meet the regulatory standard.

Why the other options are wrong

  • A. Hot water rinsing alone does not disinfect implements per Title 16 standards.
  • C. Wiping with a dry towel does not disinfect or kill pathogens.
  • D. Disinfection must occur after each client use, not batched at day's end.

Tweezer/Implement Disinfection (CA Title 16)

California regulations require metal implements like tweezers to be cleaned and completely immersed in an EPA-registered hospital-grade disinfectant for the full contact time after each client use.

  • Applies to all reusable, non-porous metal implements
  • Disinfectant must be EPA-registered and hospital-grade
  • Full immersion for the manufacturer's contact time is required
