Infection Control and Safety
What this domain tests
Safety questions test the chain of infection, levels of decontamination, hand hygiene, PPE, bloodborne pathogen handling, and emergency readiness in an esthetic setting. The exam expects you to know what must be disinfected, what must be discarded, and what requires sterilization.
Core rules
- Cleaning removes debris before disinfection; disinfecting kills most pathogens on surfaces; sterilizing destroys all microbial life including spores, usually by autoclave.
- Use an EPA-registered hospital-grade disinfectant with the label contact time. Quaternary ammonium, accelerated hydrogen peroxide, and bleach have different compatibilities.
- Standard precautions treat all blood and body fluids as infectious. Wear gloves for extraction, handle sharps in a puncture-resistant container, and never recap or bend a blade.
- Single-use items such as blades, needles, cotton, and wooden spatulas are discarded. Porous items that touch blood require sterilization or disposal.
- Handwashing with soap and water is required when hands are visibly soiled and after glove removal; alcohol rub is an alternative when hands are not visibly soiled.
Worked example
During extraction, a lesion bleeds onto your gloved finger. Stop, remove the glove without touching the outside, wash hands, apply a new glove, clean the area with an appropriate antiseptic, bag contaminated waste, and disinfect the work surface with the labeled contact time. The reasoning: blood is a bloodborne pathogen risk, and the sequence prevents cross-contamination of the client, you, and the room.
Traps
Do not double-dip implements. Do not rely on UV cabinets as a substitute for disinfection. Do not use a disinfectant before cleaning. Do not skip contact time.
