A GFCI (ground fault circuit interrupter) outlet is important in a facial treatment room because it
- Shuts off power quickly if it senses a current leak, reducing shock risk near water — Correct answer
- Increases the voltage available for machines
- Automatically sterilizes electrical tools
- Charges cordless devices faster
Explanation: GFCI outlets protect against electric shock in wet environments, which is critical since facial treatments involve water and moist skin.

Why should an esthetician never operate electrical facial machines with wet hands or near standing water?
- Water conducts electricity and greatly increases the risk of shock — Correct answer

Explanation: Water is an excellent conductor, so contact between electrical equipment, water, and skin sharply raises the danger of electric shock.
