Infection Control, Sanitation, and Safety
Infection control, sanitation, and safety is the domain most likely to decide a pass or fail, and North Dakota exam questions test definitions, contact times, reuse rules, and incident response rather than slogans.
The four levels
- Cleaning - detergent and water; removes visible debris. It must come first, because disinfectant cannot penetrate soil or hardened product.
- Sanitizing - reduces bacteria on surfaces to a level public health considers safe.
- Disinfection - an EPA-registered, hospital-grade, tuberculocidal product applied to nonporous implements. Fully immerse and time it by the label, commonly 10 minutes.
- Sterilization - destroys all microorganisms, spores included; an autoclave task, rarely needed for nail services.
Reusable versus single-use
Files, buffers, wooden pushers, cotton, toe separators, and foam are porous and go in the trash after one client. Metal nippers and pushers are cleaned, dried, immersed, then stored in a covered container. Single-use bits are never disinfected and reused.
When something goes wrong
Stop, glove, apply antiseptic, bandage, discard contaminated porous items, clean then disinfect reusable tools, and record the incident. Never drop a debris-covered implement into a shared disinfectant jar.
Worked example
A nipper nicks a client's cuticle. The tech wipes the nipper with a disinfectant wipe and keeps working. Three errors: visible debris was not removed first, wiping is not immersion, and the label contact time was ignored. The correct sequence is to stop the bleeding, finish the service, then clean and immerse the tool.
Traps
Believing UV lamps sterilize tools; assuming a quick dip equals disinfection; reusing a buffer because it "looks clean"; disinfecting without cleaning.
