Sanitation and Safety
What this domain tests
Sanitation and safety questions are about the workspace rather than the pathogen: how the station is set up, how chemicals are stored and ventilated, how water and electricity are kept apart, and how client screening prevents a service that should never start.
Station and workflow
Set up with a clean towel, a lined covered trash, and a separate sharps container for blades and any item that can cut. Keep a designated handwashing sink with soap and single-use towels; it may not be used to dump chemical waste. Segregate dirty from clean: soiled implements go to a labeled contaminated tray, never back onto the work towel, and clean tools come out of a closed drawer rather than an open bin under used linens.
Chemicals and air
Monomers, primers, and acetone need local exhaust ventilation at the table, lids kept closed, and storage away from heat, flame, and direct sun. Keep the manufacturer's Safety Data Sheet (SDS) for every product on the premises and know where it is - an unavailable SDS fails an inspection. No food, drink, or smoking at the station, and never decant product into unlabeled bottles.
Water, electricity, client screening
Use GFCI outlets near sinks and keep cords out of standing water. Footbaths: drain, scrub the basin and jet screen, disinfect for the label contact time, and dry before the next client; single-use liners do not replace basin disinfection. Screen each client for diabetes, anticoagulants, poor circulation, open lesions, or recent surgery, then modify or decline the service.
Worked example
A new tech sets up a pedicure with a fan blowing across an open monomer bottle, an extension cord draped over the sink, and no SDS binder. Three failures: ventilation must capture vapor at the table rather than push it around the room; water plus a non-GFCI cord is a shock hazard; and missing SDS documentation is a violation before any service begins.
Traps
Equating mopping a floor with sanitizing implements, storing clean towels beside soiled ones, and ignoring a client's "minor" cut or a diabetes disclosure.
