Sanitation, Sterilization, and Infection Control
Sanitation, Sterilization, and Infection Control
This domain tests how you stop pathogen transmission between clients and staff: cleaning, disinfection, sterilization, hand hygiene, and blood-exposure response. Montana barber rules and standard infection-control practice require you to match the process to the item and the risk.
Core rules
- Clean first. Remove hair, skin, and product residue before disinfectant contact; organic matter can inactivate many disinfectants.
- Disinfection kills most pathogenic organisms on hard, nonporous surfaces. Use an EPA-registered hospital-grade disinfectant at the label dilution and full contact time.
- Sterilization destroys all microbial life, including spores. It is reserved for items that penetrate skin or contact blood; routine barbering usually uses disinfection, not sterilization.
- Porous items that cannot be disinfected-neck strips, cotton, wooden sticks, used razor blades-are single-use and discarded.
- Wash hands before and after each client, after removing gloves, and after contact with blood or body fluids.
- For a blood spill: stop service, glove, absorb, clean, disinfect with a tuberculocidal product, and dispose of waste according to shop policy and Montana rules.
Worked example
A clipper blade nicks a client and draws blood during a fade. The blade is not sterile, and the cut is a blood exposure. Stop, glove, clean and cover the wound, then remove hair and debris from the blade, disinfect it with a tuberculocidal hospital disinfectant for the full label contact time, and discard any used porous item. If the barber was also exposed, follow the shop exposure-control plan.
Traps
Calling a UV cabinet or a jar of blue liquid 'sterilization'; skipping pre-cleaning; topping off disinfectant; leaving tools in disinfectant beyond label directions; wiping a blade with a towel and calling it clean.
