Section 1.7: Salon/Spa Sanitation Standards

Three Levels of Infection Control

In the esthetics profession, keeping the spa environment clean is a legal and ethical requirement. The three distinct levels of infection control are:

• Cleaning (Sanitation): The lowest level. It involves physically removing visible dirt, debris, and many disease-causing germs from surfaces using soap, water, and friction. Cleaning does not kill pathogens, but it reduces their numbers. It is a critical first step because organic matter (like sebum, dead skin cells, or makeup) can neutralize disinfectants.
• Disinfection: The second level. It uses chemical products to destroy harmful bacteria, viruses, and fungi on non-porous surfaces. Disinfection does not kill bacterial spores. Salon disinfectants must be EPA-registered, hospital-grade, and broad-spectrum (bactericidal, virucidal, and fungicidal).
• Sterilization: The highest level. It completely destroys all microbial life, including highly resilient bacterial spores. Sterilization is achieved using high-pressure steam autoclaves or dry heat. In esthetics, sterilization is required for multi-use tools that penetrate or break the skin, such as lancets or comedone extractors used in deep extractions.

Cleaning and Disinfecting Salon Surfaces

All work surfaces, treatment chairs, facial beds, and product carts must be cleaned and disinfected before and after every client. Estheticians must first clean the surface with soap and water or a cleaning spray to remove oils and dust. Next, apply an EPA-registered hospital-grade disinfectant spray or wipe. The surface must remain visibly wet for the full contact time specified on the manufacturer's label. For liquid sprays, this is typically 10 minutes; for disinfecting wipes, it may range from 2 to 4 minutes. Skipping this contact time means the surface is not disinfected.

Step-by-Step Disinfection of Multi-Use Tools

Multi-use (reusable) tools, such as metal tweezers and comedone extractors, must go through a rigid disinfection process:

1. Wear safety gear: Put on safety glasses and disposable gloves to protect your skin and eyes from chemical exposure.
2. Wash the tools: Wash the tools thoroughly with warm water and liquid soap, using a clean nylon brush to scrub away any organic residue.
3. Rinse completely: Rinse all soap residue off the tools under running water.
4. Dry the tools: Dry the tools thoroughly with a clean paper towel. Immersing wet tools into disinfectant dilutes the chemical solution, rendering it ineffective.
5. Immerse in disinfectant: Fully submerge the dry tools in a container filled with EPA-registered hospital-grade disinfectant. Ensure the tools are completely covered by the liquid.
6. Maintain contact time: Leave the tools immersed for the full contact time specified on the label (usually 10 minutes).
7. Remove and rinse: Remove the tools using clean tongs or gloved hands, rinse them under running water, and dry them with a clean paper towel.
8. Store properly: Store the disinfected tools immediately in a clean, dry, closed, and labeled container.

Multi-Use vs. Single-Use Items

Understanding the difference between multi-use and single-use items is essential for client safety and exam success. The distinction lies in whether the item is porous or non-porous:

• Multi-use (Non-porous): Made of metal, glass, or hard plastic. These items do not absorb liquids and can be cleaned and disinfected repeatedly. Examples include metal extractors, glass high-frequency electrodes, metal tweezers, and plastic mixing bowls.
• Single-use (Porous): Made of wood, paper, cotton, or sponge. These items absorb fluids and cannot be disinfected. They must be thrown away in a closed trash receptacle immediately after one use. Examples include wooden wax spatulas, cotton pads, paper towels, gauze, sponge wedges, and emery boards.

Storing Clean and Soiled Items

To prevent cross-contamination, clean and soiled items must be strictly separated.

• Clean tools and linens must be stored in clean, closed, dry cabinets or containers that are clearly labeled "Clean" or "Disinfected."
• Soiled tools must be placed immediately after use into a closed, labeled container marked "Soiled Tools" or "Dirty Tools." Soiled tools must never touch clean surfaces or be stored with clean items.
• Soiled linens and towels must be placed in a closed laundry hamper. They must be washed separately from household laundry in hot water (at least 140°F) with bleach.

State Board Exam Traps

• The Wet Tool Trap: Do not submerge wet tools in disinfectant. The water on the tools dilutes the disinfectant, making it non-compliant and unsafe.
• The Closed Container Rule: Drawers and open shelves are not considered "closed containers." Storing disinfected tools loose in a drawer violates sanitation standards. They must be in a sealed or closed container inside the drawer.
• Porous Item Disinfection: Do not choose options suggesting that sponges or wooden spatulas can be disinfected by soaking them. Porous items can never be disinfected.
