Infection Control, Sanitation, and Safety Practices
Start with the three-level distinction
Nearly every question in this domain begins with the same comparison. Cleaning removes visible debris and many microorganisms. Disinfection destroys most pathogenic organisms on hard, nonporous surfaces using an EPA-registered hospital-grade disinfectant at the label's exact dilution and contact time. Sterilization destroys all microbial life, including spores, and is not what a salon is expected to perform.
Know the organisms and the items
Be able to sort microorganisms into bacteria (cocci, bacilli, spirilla), viruses, fungi, and parasites, and to explain that pathogenic means disease-causing while nonpathogenic organisms are harmless. Bloodborne pathogens (HBV, HCV, HIV) drive the blood-spill procedure: gloves, absorbent material, disinfectant, biohazard bag, hand hygiene.
Classify implements as nonporous (metal pushers, nippers, metal files, drill bits) versus porous (wooden sticks, cotton, buffer blocks, terry towels). Nonporous items can be disinfected only after scrubbing, because debris shields organisms from the chemical. Porous items cannot be reliably disinfected; discard or launder them. Use single-use items wherever possible.
Traps that appear in questions
- Using sterilize and disinfect interchangeably in a distractor.
- An implement that is merely wiped with a disinfectant wipe instead of immersed for the full contact time.
- Assuming a UV cabinet disinfects; it is storage only.
- Rinsing a foot spa instead of cleaning and disinfecting it per the manufacturer.
Rule of thumb
When more than one answer looks reasonable, choose the step that comes first: wash hands, or clean the implement before disinfecting it. Sequence questions reward the order clean, then disinfect, then store.
