Sanitation, Disinfection, and Infection Control
This domain tests sanitation, disinfection, and infection control: the difference between cleaning and disinfection, correct use of EPA-registered hospital-grade disinfectants, handling of blood and body fluids, and safe storage of tools.
Core rules
- Clean first: remove hair, product, and debris; wash with soap and water; rinse; dry before immersion.
- Disinfect nonporous implements with an EPA-registered hospital-grade disinfectant mixed at label dilution and left for the full contact time.
- Porous items that cannot be disinfected-wood, foam, some brushes, emery boards-are single-use or client-specific.
- Keep clean and dirty tools separate; store clean tools in a covered container.
- Wash hands before and after each client; wear gloves for blood or body-fluid contact; discard single-use gloves.
- Launder towels and capes in hot water; keep products capped; never double-dip.
Worked example
After a fade and beard line, the clipper blade has visible hair and a nick caused a tiny blood spot. The correct sequence is: put on gloves, clean the blade with soap and water and a brush, dry it, then immerse or wipe with the hospital-grade disinfectant for the labeled contact time; treat the blood spot as potentially infectious, dispose of contaminated materials properly, and disinfect the workstation. A quick spray of sanitizer is not enough because it does not meet the disinfection contact time.
Traps
- Calling a surface disinfected after a spray-and-wipe.
- Using a jar of disinfectant that is cloudy or contains hair.
- Trusting a UV cabinet instead of chemical disinfection.
