Infection Control, Sanitation, and Safety
This domain tests how well you can stop the spread of pathogens in a barbershop: classifying microorganisms, choosing sanitation, disinfection, or sterilization for each item, and reacting correctly to a blood exposure. Questions are scenario-heavy, so link every rule to a tool, surface, or client interaction.
Levels of control
- Sanitation is mechanical cleaning with soap or detergent and water; it removes visible soil and reduces microbes and must come before disinfection.
- Disinfection uses an EPA-registered chemical to destroy most pathogens on nonporous implements; the label contact time is part of the rule.
- Sterilization destroys all microorganisms, including spores; use it for items that penetrate skin when your state allows.
- Blood or body fluid requires a hospital disinfectant with a tuberculocidal claim, gloves, absorbent material, closed waste disposal, handwashing, and documentation.
Implements and surfaces
- Clean, dry, then disinfect nonporous tools; store them in a closed, labeled container, not in standing liquid.
- Towels, neck strips, cotton, and other porous items are single-use or properly laundered; capes are changed between clients.
- Unplug electrical tools before cleaning; never put water into a clipper motor; oil and align blades.
- Wash hands before and after service; wear gloves for blood; do not double-dip applicators.
Worked example
A razor slips and nicks a client. Stop, glove, blot with a disposable towel, place waste in a closed container, clean the razor, then submerge it in an EPA hospital tuberculocidal disinfectant for the label contact time, often 10 minutes. Wash hands and record the incident. A quat-only wipe or a UV cabinet would not meet the blood-exposure standard.
Traps that cost marks
Calling disinfection sanitation, skipping cleaning before disinfecting, ignoring contact time, reusing neck strips, storing tools wet, and assuming ultraviolet cabinets sterilize.
