Sanitation, Safety, and Infection Control
What this domain tests
Sanitation, safety, and infection control questions ask you to distinguish cleaning, disinfection, and sterilization and to apply the right process to tools, hands, linens, and surfaces. The exam favors a practical sequence: clean first, then disinfect with an EPA-registered product used exactly per its label.
Core rules
- Wash hands with soap and water before and after each client; use an alcohol-based sanitizer only when hands are not visibly soiled.
- Clean removes visible debris; disinfection kills most pathogens on nonporous implements; sterilization destroys all microbial life and is not achieved by ordinary shop UV cabinets.
- After every client, remove hair and product from clippers, shears, combs, and razors, then disinfect nonporous items by immersion or according to the manufacturer's contact time.
- Use single-use blades, neck strips, and porous items; launder linens and towels after each use.
- If blood or body fluid is present, wear gloves, stop service, clean and disinfect the area and tools with a tuberculocidal or bloodborne-pathogen-effective hospital disinfectant, and dispose of contaminated sharps in a sharps container.
Worked example
A clipper blade nicks a client and a drop of blood appears. The correct reasoning is not to wipe the blade with a dry towel. Stop, glove, contain the blood, clean the blade to remove debris, then disinfect with an EPA-registered hospital disinfectant labeled effective against HIV and HBV for the full contact time. The cape and neck strip are changed, and the contaminated disposable is bagged.
Traps
Assuming a sanitizer spray equals a disinfectant, dipping tools briefly and removing them before contact time, or trusting a UV cabinet as sterilization all lose marks. Also watch for reusing a razor blade because it looks clean.
