Sanitation, Sterilization and Safety
Sanitation, disinfection and sterilization are not synonyms, and most missed items on this topic come from treating them as if they were. Sanitation reduces microorganisms on a surface to a safe public-health level - it is what soap, water and detergent accomplish. Disinfection destroys most pathogenic organisms on nonporous surfaces but not necessarily bacterial spores; that is why implements that contact blood or break the skin require an EPA-registered hospital-grade disinfectant carrying a tuberculocidal claim. Sterilization destroys all microbial life including spores and is a medical-setting process, not a barbering one. A UV cabinet is a storage aid, never a substitute for chemical disinfection.
Know the workflow: clean first (soap and water to remove hair, debris and product), then disinfect (immerse or wipe for the full contact time on the label), then store in a clean closed container. Disinfectant solutions are changed on the manufacturer's schedule, never simply topped off. Single-use items - neck strips, cotton, wooden applicators, styptic - are used once and discarded, and creams and powders are dispensed with a clean spatula so nothing is double-dipped. Hands are washed before and after every client, and gloves are worn for any blood contact.
Blood exposure: stop the service, don gloves, absorb the spill, clean, then disinfect with an appropriate hospital-grade product or a fresh 1:10 bleach solution, double-bag the waste, wash hands, and report per shop policy.
Rule of thumb: if an item can nick skin or has touched broken skin, it must be disinfected with a tuberculocidal product; if it is porous and cannot be disinfected, it is discarded.
