Infection Control, Sanitation, and Safety Practices
The core idea
Infection control questions hinge on two things: the level of control a situation demands, and the order of steps. Learn the ladder - cleaning (soap and water, removes visible debris), sanitizing (reduces bacteria on surfaces), disinfecting (an EPA-registered hospital-grade product that kills pathogens, applied by full immersion for the label contact time), and sterilizing (an autoclave; destroys all microbial life including spores). Anything that touches skin, nails, or blood must be cleaned first, then disinfected - debris shields microbes from the chemical. Porous items (wooden sticks, cotton, foam buffers, emery boards, unlaunderable linens) cannot be reliably disinfected and must be discarded.
Know the pathogen groups: cocci, bacilli, and spirilla (bacteria); hepatitis B and C and HIV (bloodborne viruses); tinea (fungi); pediculosis (parasites). Spore-formers are the hardest to kill. Standard precautions treat every client's blood and body fluids as infectious: gloves, hand washing, sharps disposal, and a blood-spill kit using a tuberculocidal hospital disinfectant.
Safety overlaps heavily. OSHA's Hazard Communication Standard requires a Safety Data Sheet for every chemical in the salon; containers stay labeled, closed, and away from heat; electrical cords are inspected and kept away from water; ventilation matters with monomers and relaxers.
Traps
- Sterilize vs. disinfect: an autoclave sterilizes, a jar of quat concentrate disinfects.
- Wiping is not disinfection; immersion is.
- Mixing disinfectant stronger than the label does not make it better - it often makes it unsafe or less effective.
Rule of thumb
Touches skin, nails, or blood? Clean, disinfect with an EPA-registered hospital-grade product for the full label time, store covered. Porous and single-use? Use once, discard.
