Health and Safety: Decontamination, Client Protection, and Salon Practice
The three levels of decontamination
Candidates must be able to separate sterilization (destroys all microbial life, including bacterial spores), disinfection (destroys most pathogenic organisms on hard, nonporous surfaces but not necessarily spores), and sanitation (a simple physical cleaning that reduces the number of microorganisms). California's operating standard for reusable implements is disinfection, not sterilization - an autoclave is optional, but an EPA-registered hospital-grade disinfectant is not.
Clean, then disinfect
Disinfection only works on a clean surface. The sequence is: remove visible debris, wash with soap and water, dry, then fully immerse the implement in an EPA-registered hospital-grade disinfectant for the contact time printed on the label, and store it in a clean, covered container. Question writers love to substitute a shortcut - rubbing alcohol, a bleach wipe, a UV cabinet, or a quick spray - for the labeled immersion step. Unless the product label itself states hospital-grade disinfection, it does not meet the standard.
Single-use and porous items
Anything that cannot be adequately disinfected is used once and discarded: nail files, buffers, wooden sticks, cotton, sponges, razor blades, and porous items that contact skin. Products must be dispensed so that containers, hands, and tools never contaminate the remaining supply. Never double-dip.
Your hands are an implement
Wash hands with soap and water before and after every client and before gloving. Wear gloves for any blood or body-fluid contact; for a blood exposure, stop the service, glove, clean the area, and use a tuberculocidal hospital-grade disinfectant. Keep Safety Data Sheets available for every chemical in the salon, and never apply a surface disinfectant to a client's skin - skin is protected, not disinfected.
Rule of thumb: if you cannot clean it and fully immerse it, it is single-use.
Worked example: a manicurist wipes nippers with alcohol between clients. That fails: no debris removal, no labeled contact time, and alcohol is not a hospital-grade disinfectant. The correct answer is wash, dry, immerse per label, store covered.
