Sanitation, Disinfection, and Safety Practices
Sanitation, disinfection, and safety is the domain that separates a licensed esthetician from an unlicensed operator. The Colorado exam tests how you classify implements, select an EPA-registered product, follow contact time, and respond to spills and injuries without improvising. Expect questions that sound simple but turn on one word: clean, sanitize, disinfect, or sterilize.
The three levels
- Cleaning removes visible debris with soap or detergent and water. It must happen before disinfection because soil protects organisms.
- Disinfection destroys most pathogenic organisms on nonporous surfaces but not spores. Esthetics uses an EPA-registered hospital-grade, tuberculocidal disinfectant.
- Sterilization destroys all microorganisms, including spores. It is not the routine esthetics standard.
Daily rules
- Wash hands before and after every client, and after removing gloves.
- Wear gloves for waxing, extractions, and any contact with blood or body fluids.
- Nonporous implements such as metal tweezers, comedone extractors, and scissors: clean, dry, completely immerse in disinfectant for the label contact time, then remove with clean tongs, dry, and store in a covered clean container.
- Porous or single-use items such as wax strips, cotton, wooden spatulas, and lancets: discard. Do not disinfect and reuse.
- Label disinfectant containers with product name and date; do not top off; change solution per manufacturer.
- UV cabinets and towel warmers are not disinfectants.
- Blood exposure: stop service, glove, absorb with disposable towel, clean, disinfect with hospital-grade product, bag waste as biohazard, wash hands, and document. Keep SDS accessible.
- Keep cords away from water and alcohol away from flame.
Worked example
A metal extraction tool falls on the floor. Wiping it with 70% alcohol is not enough. With gloves on, scrub it with detergent and water to remove debris, dry it, submerge it completely in hospital-grade disinfectant for the labeled contact time, remove it with clean tongs, rinse only if the label says to, dry, and store it covered. If the tool is porous, cracked, or rusted, discard it.
Traps
- Treating 'sanitizer' or 'antibacterial' as a synonym for hospital-grade disinfectant.
- Skipping cleaning before immersion.
- Timing by habit instead of the product label.
- Double-dipping spatulas or reusing wax strips.
- Storing implements in disinfectant overnight when the label does not allow it.
