Per California Code of Regulations Title 16, how long must nail implements be immersed in an EPA-registered disinfectant to be considered properly disinfected?
- A10 minutes or the manufacturer's required contact time, whichever is greater
- B5 minutes
- C1 minute
- D30 seconds
Show answer & explanationAnswer & explanation
Correct answer: A. 10 minutes or the manufacturer's required contact time, whichever is greater
California regulations require multi-use implements to be completely immersed in an EPA-registered disinfectant for the full contact time specified on the product label, which is at least 10 minutes, before being removed, rinsed, dried, and stored in a clean, covered container.
Why the other options are wrong
- B. Five minutes is insufficient; California requires the full labeled contact time (minimum 10 minutes).
- C. One minute is far too short to achieve proper disinfection.
- D. Thirty seconds is grossly inadequate for disinfection.
Implement Disinfection Time
California requires nonporous, multi-use implements to be fully immersed in an EPA-registered hospital disinfectant for at least 10 minutes (or longer per label instructions).
- Implements must be cleaned of debris before disinfecting
- Disinfectant must be EPA-registered and hospital-grade
- Store dry, disinfected tools in a clean, covered container
Memory trick: Ten full minutes — no shortcuts on the clock.
