Infection Control and Safety Practices

What this domain tests

Infection control questions ask you to match a client-care risk to the correct process: cleaning, disinfection, or sterilization. The exam also checks salon safety and bloodborne-pathogen precautions.

Core rules

  • The chain of infection has six links: pathogen, reservoir, portal of exit, transmission, portal of entry, susceptible host. Infection control breaks a link.
  • Clean before disinfecting. Detergent and water remove soil, oils, and many organisms; disinfectants are weakened by organic matter.
  • Disinfection uses an EPA-registered hospital disinfectant mixed at the label dilution and left for the full contact time. Sterilization destroys all microbial life and is not routine for reusable facial tools.
  • Porous items-sponges, cotton, wooden sticks, emery boards-are single-use. Nonporous metal or glass tools are cleaned, disinfected, and stored covered.
  • Gloves are not a substitute for handwashing. Treat blood and body fluids as infectious; report exposures.
  • Safety: keep cords dry, label chemicals, keep SDS sheets accessible, and ventilate wax and chemical areas.

Worked example

A metal extractor is visibly soiled after use on a pustule. Correct order: put on gloves, remove debris, scrub with detergent and water, rinse and dry, then immerse in hospital disinfectant for the label contact time, dry, and store covered. Reasoning: disinfectant cannot penetrate soil, so cleaning is not optional.

Traps

Calling a spray a sterilant; disinfecting a wooden stick; topping off disinfectant; skipping contact time; wearing the same gloves to two clients.
