Section 1: Disinfection & Sterilization
Core Concepts
Understanding the hierarchy of decontamination is foundational to the exam. These levels are not interchangeable.
| Level | What It Destroys | Example Methods |
|---|---|---|
| Sanitization | Reduces microorganisms to safe levels | Soap and water, UV cabinets |
| Disinfection | Destroys most pathogens (NOT spores) | Quats, bleach solution |
| Sterilization | Destroys ALL microorganisms including spores | Autoclave (pressurized steam) |
Key Definitions
• Disinfection – Destroys most microorganisms on non-living surfaces; does NOT kill bacterial spores
• Sterilization – Destroys ALL microorganisms, including spores; achieved via autoclave
• Autoclave – A device using pressurized steam at high temperatures to achieve full sterilization
• Quaternary Ammonium Compounds (Quats) – The most commonly used salon disinfectant; effective against bacteria, viruses, and fungi; non-corrosive to most implements
• Sodium Hypochlorite (Bleach Solution) – Diluted at a 1:10 ratio (1 part bleach to 9 parts water) for salon disinfection
• Contact Time – The amount of time a disinfectant must remain in contact with a surface to be effective; most EPA-registered hospital-grade disinfectants require 10 minutes
• Non-critical items – Items that contact only intact skin; require low-level disinfection
The Two-Step Rule: Clean THEN Disinfect
```
Step 1: CLEAN → Scrub with soap and water to remove ALL visible debris
Step 2: DISINFECT → Fully submerge in EPA-registered disinfectant for required contact time
```
> Organic matter (skin cells, oils, blood) inactivates disinfectants. Skipping the cleaning step renders disinfection ineffective.
Why UV Sanitizer Cabinets Are NOT Enough
UV cabinets are commonly misunderstood on the exam. Remember:
• UV light cannot penetrate all surfaces of an implement
• UV cabinets only sanitize (reduce organisms), they do NOT disinfect or sterilize
• They are acceptable for storing already-disinfected implements, not for disinfecting
Key Terms
• EPA-registered – Disinfectant has been approved by the Environmental Protection Agency
• Hospital-grade disinfectant – Meets higher efficacy standards; required for salon use
• Spore – A dormant, highly resistant form of bacteria that only sterilization can destroy
• Immersion – Implements must be fully submerged in disinfectant, not just wiped
⚠️ Watch Out For
• Do not confuse sanitization with disinfection — they are different levels of decontamination
• The exam may ask about UV cabinets being a form of disinfection — the answer is NO
• Bleach must be diluted correctly — undiluted bleach is not safer; it can damage tools and is hazardous
• Contact time matters — removing an implement before 10 minutes invalidates the disinfection process
• Change disinfectant solutions daily or when visibly cloudy — dirty solution is ineffective

Section 2: Infection Control & Microbiology
Types of Microorganisms
| Type | Key Facts | Salon Examples |
|---|---|---|
| Bacteria | Single-celled; can be aerobic or anaerobic | Staph, strep |
| Viruses | Require a host cell to replicate | Herpes (HSV-1), Hepatitis B |
| Fungi | Includes molds, yeasts, mildew | Tinea (ringworm), tinea versicolor |
Key Definitions
• Pathogen – Any microorganism capable of causing disease or infection
• Aerobic bacteria – Bacteria that require oxygen to survive and grow (most common in salon)
• Communicable disease – Can be transmitted from person to person (direct or indirect contact)
• Non-communicable disease – Cannot be passed between individuals
• Contraindication – A condition that makes a particular treatment inadvisable or unsafe
Bloodborne Pathogens: Priority Concerns
• Hepatitis B Virus (HBV) – Primary bloodborne concern in salons
- Can survive on dry surfaces for up to 7 days
- Transmitted through contact with infected blood
- Significantly more hardy than HIV in the environment
• HIV – Also a concern but far less hardy outside the body than HBV
Contraindications: Know These Cold
| Condition | Cause | Why It's a Contraindication |
|---|---|---|
| Active cold sore (herpes labialis) | HSV-1 (Herpes Simplex Virus) | Highly contagious; services can spread or worsen outbreak |
| Tinea versicolor | Fungal infection | Manipulation can spread infection to other areas |
| Any open wound or active infection | Various | Risk of spreading pathogens to client or esthetician |
Key Terms
• HSV-1 – Herpes Simplex Virus Type 1; causes oral cold sores; a facial contraindication
• Tinea – Fungal infections of the skin (tinea versicolor, tinea corporis/ringworm)
• HBV – Hepatitis B Virus; the most resilient bloodborne pathogen in the salon context
• Direct transmission – Physical contact between infected and uninfected person
• Indirect transmission – Contact via contaminated surface, tool, or droplet
⚠️ Watch Out For
• Do not confuse aerobic (requires oxygen) with anaerobic (thrives without oxygen)
• A client with an active cold sore is a contraindication — even if it looks like it's healing
• Tinea versicolor is fungal, not bacterial — this distinction matters for treatment approach
• HBV, not HIV, is the primary bloodborne pathogen concern in the salon setting due to its surface durability

Section 3: OSHA & Regulatory Compliance
The Key Players
| Agency | Role |
|---|---|
| OSHA | Sets workplace safety standards; governs chemical handling |
| EPA | Registers and approves disinfectant products |
| California BBC (Board of Barbering and Cosmetology) | Licenses estheticians; enforces CA-specific sanitation regulations |
OSHA's Key Requirements
• Safety Data Sheets (SDS) – Formerly called MSDS (Material Safety Data Sheet)
- Required for every hazardous chemical in the workplace
- Must be readily accessible at all times for employees and emergency responders
- Contains: hazards, safe handling, first aid, disposal guidelines
• Hazard Communication Standard (HazCom) – Requires:
1. Proper training for all employees handling hazardous chemicals
2. Access to SDS for all hazardous chemicals
3. Proper labeling of all chemical containers
SDS: What It Contains
• Chemical identity and physical properties
• Health hazards and exposure limits
• Protective equipment required
• First aid procedures
• Spill and disposal procedures
• Emergency contact information
California BBC Authority
• Oversees esthetician licensing in California
• Enforces sanitation and safety regulations in cosmetology establishments
• Conducts inspections of salons for compliance
• Issues violations for improper sanitation practices
Key Terms
• OSHA – Occupational Safety and Health Administration
• SDS / MSDS – Safety Data Sheet / Material Safety Data Sheet
• BBC – California Board of Barbering and Cosmetology
• HazCom – OSHA's Hazard Communication Standard
• EPA-registered – Disinfectant approved by the Environmental Protection Agency
⚠️ Watch Out For
• SDS sheets are not optional — OSHA requires them to be accessible at all times
• Know the difference between OSHA (federal workplace safety) and BBC (California licensing)
• The exam may use both "MSDS" and "SDS" — they refer to the same document (SDS is the updated term)
• Employers are responsible for providing training — not just making SDS available

Section 4: Personal Protective Equipment (PPE) & Safe Practices
Required PPE by Situation
| Service/Situation | Required PPE |
|---|---|
| Extractions | Gloves + protective eyewear (goggles or face shield) |
| Chemical applications | Gloves; eyewear if splash risk |
| Blood exposure risk | Gloves always; eyewear if splash possible |
| Routine services | Gloves recommended |
Handwashing Protocol (CDC Standard)
```
1. Wet hands with clean running water
2. Apply soap
3. Scrub ALL surfaces for at least 20 SECONDS
(Sing "Happy Birthday" twice as a timer)
4. Rinse thoroughly under running water
5. Dry with clean towel or air dryer
```
> Wash hands before and after every client, after removing gloves, after touching contaminated surfaces, and after any potential exposure.
Proper Glove Removal Technique
```
Step 1: Pinch the OUTSIDE of one glove near the wrist
Step 2: Peel it OFF, turning it inside-out
Step 3: Hold the removed glove in your GLOVED hand
Step 4: Slip fingers UNDER the remaining glove at the wrist
Step 5: Peel it off inside-out, encasing the first glove
Step 6: Dispose of both gloves without touching outer surfaces
```
Blood Exposure Response Protocol
If accidental blood exposure occurs during a service:
1. Stop the service immediately
2. Apply pressure to the wound if applicable
3. Wash the exposed area immediately with soap and water
4. Apply a bandage and change gloves
5. Disinfect the work area and all contaminated surfaces
6. Document the incident per workplace policy
7. Advise client to seek medical attention if needed
Sharps Disposal
• Single-use sharps (lancets, needles) must go directly into an approved puncture-resistant sharps/biohazard container
• Never place sharps in regular trash
• Never recap a used sharp by hand
• Sharps containers must be disposed of according to local biohazard waste regulations
Key Terms
• PPE – Personal Protective Equipment (gloves, eyewear, masks)
• Bloodborne pathogen – Infectious microorganism present in blood (HBV, HIV)
• Sharps container – Puncture-resistant, biohazard-labeled container for used sharps
• Exposure incident – Contact with blood or body fluids that may transmit infection
⚠️ Watch Out For
• Gloves are required for extractions — not just when blood is visible
• Protective eyewear is also required during extractions (not just gloves)
• Hand sanitizer is not a substitute for soap and water handwashing in all situations
• A used lancet placed in regular trash is a regulatory violation
• Always change gloves between clients — never reuse gloves

Section 5: Salon Sanitation Procedures
The Complete Implement Decontamination Sequence
```
1. CLEAN → Scrub with soap and water; remove ALL visible debris
2. RINSE → Remove all soap residue
3. DISINFECT → Fully immerse in EPA-registered disinfectant for full contact time (10 min)
4. RINSE & DRY → Remove disinfectant residue; dry thoroughly
5. STORE → Place in a clean, closed, covered container or cabinet
```
> This sequence is non-negotiable and must be performed in this exact order.
Single-Use Items: The Non-Negotiable Rule
These items are ALWAYS discarded after one use:
• Cotton pads and gauze
• Wax applicators (spatulas)
• Extraction lancets
• Disposable gloves
• Tissue and paper products
> Single-use items can never be recleaned, disinfected, or used on another client regardless of appearance.
Between-Client Surface Sanitation
Before each new client, the esthetician must:
• Apply fresh, clean linens or a disposable covering to the treatment chair/facial bed
• Disinfect all multi-use surfaces (treatment table, magnifying lamp, equipment handles)
• Ensure all implements used on the previous client are properly decontaminated
Disinfectant Solution Maintenance
| Requirement | Standard |
|---|---|
| Frequency of change | At least daily or whenever visibly cloudy/contaminated |
| Why it matters | Contaminated solution loses efficacy; cannot properly disinfect |
| Proper labeling | Containers should be labeled with solution type and date mixed |
Clean vs. Contaminated: Storage Rules
• Clean/disinfected implements → Stored in a clean, closed, covered container
• Contaminated/used implements → Kept separate; must be decontaminated before storage
• Never store clean and dirty implements together
Key Terms
• Single-use/disposable – Items intended for one-time use only; must be discarded after each client
• Multi-use/reusable – Items that can be decontaminated and used again (metal implements)
• Contamination – The presence of potentially harmful microorganisms on a surface or tool
• Contact time – Required duration disinfectant must remain on surface/implement to be effective
• Covered container – Closed storage for clean implements to prevent recontamination
⚠️ Watch Out For
• The cleaning step (soap and water) must come before disinfection — order matters
• Disinfectant solution left past one day or that is visibly cloudy is no longer effective
• UV cabinets are acceptable for storing disinfected implements, not for disinfecting them
• Linens must be changed for each client — not just when visibly soiled
• Tools must be fully submerged — not just wiped — during the disinfection step
