1.1 Sanitation, Disinfection, and Sterilization

1.1 Sanitation, Disinfection, and Sterilization

Infection control is the foundational pillar of the cosmetology profession. The Florida Board of Cosmetology enforces strict sanitary guidelines under Chapter 61G5 of the Florida Administrative Code (F.A.C.) to protect the public and practitioners from the spread of infectious diseases.

The Three Levels of Infection Control

Infection control is divided into three distinct levels: cleaning, disinfection, and sterilization. Each tier represents a different level of pathogen reduction.

1. Cleaning (Sanitation)

Cleaning is the first level of infection control. It is a mechanical process using soap, warm water, and friction to physically remove visible dirt, debris, and many disease-causing germs. Cleaning does not kill pathogens, but it significantly reduces their numbers. It is a mandatory prerequisite before disinfection or sterilization because remaining organic matter (hair, oils, skin cells) creates a physical barrier that shields microorganisms from chemical disinfectants. Common methods include washing hands, scrubbing tools with a clean brush, or using an ultrasonic unit.

2. Disinfection

Disinfection is the second level of infection control and the standard level of defense in salons. It is a chemical process that destroys most harmful microorganisms on non-porous surfaces. While disinfectants eliminate bacteria, viruses, and fungi, they are ineffective against bacterial spores. Disinfection applies only to hard, non-porous tools (such as shears, combs, and clips) and surfaces. Disinfectants are strong chemicals and must never be used on human skin, hair, or nails.

3. Sterilization

Sterilization is the third and highest level of infection control. It completely destroys all microbial life, including highly resilient bacterial spores. This is typically achieved using high-pressure steam autoclaves or dry heat sterilizers. Sterilization is mandatory for tools that penetrate the skin or contact sterile areas of the body. Standard cosmetology styling tools do not require sterilization under Florida law, but it is standard practice in electrology and esthetic extractions.

EPA-Registered Hospital Disinfectants

The Environmental Protection Agency (EPA) registers all disinfectants sold and used in the United States. Under Florida Board Rule 61G5-20.002, F.A.C., salons must use EPA-registered hospital-grade disinfectants.

Efficacy Standards

To qualify as a hospital disinfectant, the product must be certified as:

1. Bactericidal: Capable of destroying bacteria.
2. Virucidal: Capable of destroying viruses.
3. Fungicidal: Capable of destroying fungi.

Common Disinfectant Types in the Salon

• Quaternary Ammonium Compounds (Quats): The most widely used salon disinfectants. Advanced formulations contain rust inhibitors to protect metal shears. They typically disinfect implements in 10 minutes, are odorless, and non-toxic when used correctly.
• Phenolic Disinfectants: Powerful tuberculocidal disinfectants (effective against tuberculosis). However, they have a very high pH, can damage plastics and rubber, cause severe skin irritation, and are harmful to the environment.
• Sodium Hypochlorite (Household Bleach): An effective disinfectant when diluted properly (typically 5.25% strength). Florida salons may use bleach, but it must be mixed fresh daily, stored in a cool, dark container, and is highly corrosive to metal tools.

Mixing and Safety Protocols

Proper dilution of disinfectant concentrates is critical. Using too much water renders the solution ineffective, while using too much concentrate can damage tools and cause health hazards.

The "A.D.D." Rule

When mixing concentrated disinfectants, always follow the A.D.D. rule: Add Disinfectant Down into water. Never pour water into a concentrate. Doing so causes the chemical to foam and splash, which can lead to severe eye or skin chemical burns.

Safety Equipment (PPE)

When mixing or handling disinfectants, cosmetologists must wear chemical-resistant gloves (nitrile or vinyl) to prevent contact dermatitis, and safety goggles to protect against accidental splashes.

Tool Immersion and Dwell Times

For disinfection to occur, the chemical must remain in contact with the tool for a specific duration. This is known as contact time or dwell time.

Step-by-Step Immersion Process

To properly disinfect salon implements, follow these sequential steps:

1. Clean: Wash the tools thoroughly with soap, warm water, and a clean brush to remove hair, oils, and product buildup.
2. Rinse and Dry: Rinse tools with clean water and dry them completely. Water left on tools will dilute the disinfectant solution.
3. Immerse: Submerge the tools completely in the disinfectant solution. Every part of the tool must be fully covered (complete immersion).
4. Time: Leave the tools in the solution for the manufacturer's recommended contact time. For liquid disinfectants, this is typically 10 minutes.
5. Remove and Rinse: Remove tools using tongs or gloved hands, rinse in clean water, and dry.
6. Store: Store the disinfected tools in a clean, closed, labeled container.

Florida-Specific Salon Sanitation Requirements

Under Florida Rule 61G5-20.002, F.A.C., salons must maintain specific facilities to prevent cross-contamination:

• Clean Tool Storage: Salons must store all disinfected tools in clean, enclosed, dust-free drawers, cabinets, or covered containers. These must be labeled "Clean Tools" or "Disinfected Implements."
• Soiled Tool Storage: A separate, covered, labeled container must be designated for soiled tools awaiting cleaning and disinfection.
• Pedicure Spa Disinfection: Foot spas and pedicure basins require rigorous cleaning between clients. The basin must be drained of all water, scrubbed of all debris using soap, water, and a clean brush, rinsed, refilled with clean water and an EPA-registered hospital disinfectant, circulated for a minimum of 10 minutes, and then drained, rinsed, and dried with a clean towel. At the end of each day, the screen and removable parts must be taken out, cleaned of debris, and immersed in disinfectant.
• Porous vs. Non-Porous Items: Only non-porous items (metal shears, plastic combs, glass) can be disinfected and reused. Porous items (nail files, cotton pads, wooden spatulas, buffing blocks) cannot be disinfected and must be discarded after a single use.
