Infection Control and Sanitation
Infection control is the most heavily tested area of the Nebraska nail technology exam, because almost every practical scenario can be resolved by asking two questions: what did the item touch, and who will it touch next? The exam expects you to separate cleaning, disinfection, and sterilization, to classify implements as porous or non-porous, and to apply EPA-registered hospital disinfectants correctly.
Core rules
- Cleaning with soap and water always comes first. Organic residue (skin, oil, nail dust) inactivates disinfectant, so a sprayed or immersed tool that was never cleaned is not disinfected.
- Non-porous implements that contact skin or nails (stainless steel pushers, nippers, metal files, drill bits): clean, dry, then fully immerse in an EPA-registered hospital disinfectant with a tuberculocidal claim for the label's full contact time, then dry and store covered.
- Porous items (foam buffers, porous or wooden files, orange sticks, pumice) cannot be disinfected. Use once and discard or give to the client.
- Wash hands with soap and water before and after each client; sanitizer is a supplement, not a substitute, when hands are soiled.
- Blood or body-fluid contact: wear gloves, clean, then disinfect with a tuberculocidal hospital disinfectant; absorb spills, double-bag waste, disinfect the surface.
- Footbaths: drain, clean, and disinfect with a low-foam hospital disinfectant between clients; remove and clean screens and jets.
Worked example
A technician finishes a fill and has a steel cuticle pusher, a 180-grit file, and a foam buffer. The pusher is non-porous, so it is cleaned, dried, immersed for the full label contact time, dried, and stored covered. The file and buffer are porous and cannot be disinfected, so they are discarded or given to the client. An answer that says "spray all three with disinfectant" fails: sprays do not deliver immersion contact time, and porous items are not disinfectable at all.
Traps that cost marks
UV cabinets and "sanitizer" jars do not disinfect or sterilize. Topping off a disinfectant jar dilutes the active ingredient. Placing wet tools into disinfectant dilutes it. Storing disinfected tools in an open, dusty tray recontaminates them.
