Infection Control Fundamentals
The Three Levels of Infection Control
Understanding the hierarchy of infection control is one of the most tested concepts on the state board exam.
| Level | Method | What It Does | Example |
|---|---|---|---|
| Lowest | Sanitation (Sanitizing) | Reduces the number of pathogens; does NOT kill all | Washing hands, sweeping floors |
| Middle | Disinfection | Destroys most harmful microorganisms; does NOT kill bacterial spores | Immersing combs in EPA-registered solution |
| Highest | Sterilization | Destroys ALL microbial life, including spores | Autoclave (rarely used in salons) |
> Watch Out For: Students often confuse sanitation with disinfection. Sanitation only reduces pathogens — it does not kill them all. Disinfection is required for salon implements between clients.

Microorganisms & Disease
• Pathogens – Disease-causing microorganisms including bacteria, viruses, fungi, and parasites
• Pathogenic bacteria – Harmful bacteria capable of causing disease in humans (as opposed to nonpathogenic bacteria, which are harmless or beneficial)
• Nonpathogenic bacteria – Do not cause disease; some are beneficial to the body
Types of Infection
• Local infection – Confined to a specific area of the body
• Systemic infection – Spreads through the bloodstream throughout the body
• Both begin when pathogens enter through a break in the skin or mucous membranes
Contagious vs. Non-Contagious Conditions
• Contagious (communicable) disease – Can be spread from person to person through direct or indirect contact (e.g., ringworm, conjunctivitis)
• Fomite – An inanimate object (comb, towel, implement) that can harbor and transfer pathogens without being infected itself
> Watch Out For: You must REFUSE service to any client presenting with a contagious condition and refer them to a physician. This is both a safety requirement and an Illinois state board rule.

Key "Cidal" Terms
| Term | Kills |
|---|---|
| Bactericide | Bacteria |
| Fungicide | Fungi and mold |
| Virucide | Viruses |
| Broad-spectrum disinfectant | All three — required for salon use |
---
Disinfection Methods & Products
The Correct Disinfection Process (Step-by-Step)
1. Clean the implement first — remove all visible debris, hair, and organic matter
2. Rinse thoroughly
3. Immerse fully in an EPA-registered, hospital-level disinfectant
4. Soak for at least 10 minutes
5. Remove, rinse if required by manufacturer, dry
6. Store in a clean, covered container or sealed bag
> Watch Out For: Organic matter (hair, skin, blood) can inactivate a disinfectant solution, making it ineffective. Always clean implements BEFORE placing them in disinfectant.
---
Disinfectant Products
• EPA-registered disinfectant – Approved by the Environmental Protection Agency; verified effective against the pathogens listed on the label. Required by Illinois law for salon use.
• Quaternary ammonium compounds (quats) – Common, effective EPA-registered disinfectants for hard, non-porous surfaces and implements; must be used at the manufacturer's recommended concentration
• Sodium hypochlorite (bleach) solution – A 10% bleach solution (1 part bleach to 9 parts water) is an effective disinfectant for hard, non-porous salon surfaces
The Wet Sanitizer
• A covered container holding an EPA-registered disinfectant solution
• Implements must be fully immersed
• Solution must be changed daily or immediately if it becomes visibly dirty, diluted, or contaminated
UV Sanitizers (Ultraviolet Light Cabinets)
• NOT an acceptable method of disinfection — UV light cannot reach all surfaces (shadows block the light)
• Do not meet EPA-registered disinfection standards
• May only be used for storage of implements that have already been properly disinfected
---
Porous vs. Non-Porous Implements
| Implement Type | Can Be Disinfected? | Action Required |
|---|---|---|
| Non-porous (metal combs, shears, bowls) | ✅ Yes | Clean, then disinfect |
| Porous (nail files, buffers, orangewood sticks) | ❌ No | Discard after single use |
> Watch Out For: Porous items cannot be effectively disinfected because pathogens can hide in the material's surface. Single-use items must be discarded — not cleaned and reused.
---
Key Terms – Disinfection
• EPA-registered – Government-approved disinfectant product
• Hospital-level disinfectant – Broad-spectrum product effective against bacteria, fungi, and viruses
• Wet sanitizer – Covered container used for implement immersion
• Quats – Quaternary ammonium compounds; common salon disinfectant
• 10-minute immersion – Minimum required contact time for disinfection
---
OSHA & Chemical Safety
OSHA Overview
• OSHA = Occupational Safety and Health Administration
• Sets and enforces workplace safety standards, including chemical exposure in salons
• Requires employers to train employees on all hazardous chemicals in the workplace
Safety Data Sheets (SDS)
• Replaced the old Material Safety Data Sheet (MSDS) under the updated OSHA Hazard Communication Standard
• Follows a standardized 16-section format
• Must be accessible to all salon employees at all times
#### Key SDS Sections to Know:
| Section | Content |
|---|---|
| Section 1 | Product identification |
| Section 2 | Hazard identification |
| Section 8 | Exposure Controls & Personal Protection (PPE, ventilation) |
| Section 16 | Other information |
The Right to Know Law
• Part of OSHA's Hazard Communication Standard
• Gives employees the legal right to:
- Access Safety Data Sheets
- Receive training on all hazardous chemicals used in the workplace
Personal Protective Equipment (PPE)
• PPE = Personal Protective Equipment
• Examples used in salons:
- Disposable gloves (nitrile or latex)
- Safety glasses/goggles
- Respiratory masks (for chemical services)
- Ventilation (required for chemical services)
---
Chemical Hazard Warnings
> Watch Out For (Exam Pitfall): Mixing bleach and ammonia is extremely dangerous. It produces toxic chloramine gases that can cause respiratory damage, eye irritation, and can be life-threatening in enclosed spaces. Never mix these products.
If chemicals splash into eyes:
1. Immediately flush with cool water for 15–20 minutes
2. Do NOT rub the eye
3. Seek medical attention immediately
---
Key Terms – OSHA & Chemical Safety
• OSHA – Federal agency enforcing workplace safety standards
• SDS – Safety Data Sheet; 16-section standardized chemical information document
• Right to Know law – Employee's right to access SDS and chemical training
• PPE – Personal protective equipment (gloves, goggles, masks)
• Chloramine gas – Toxic gas produced by mixing bleach and ammonia
---
Salon Safety Procedures
Handling Contagious Conditions
• Always refuse service to clients with suspicious scalp conditions, open sores, ringworm, or any other contagious condition
• Refer the client to a physician
• Performing services on clients with contagious conditions is prohibited under Illinois law
---
Blood Exposure Protocol
If a client bleeds during a service, follow this procedure:
1. Stop the service
2. Apply gloves (single-use, disposable)
3. Clean the wound and apply antiseptic
4. Cover with a bandage
5. Double-bag all contaminated materials in a sealed plastic bag
6. Disinfect all implements and surfaces that were contaminated
7. Remove and discard gloves immediately after cleanup
8. Wash hands thoroughly
> Watch Out For: Single-use disposable gloves (nitrile or latex) must be worn and then immediately discarded — never reused.
---
Sharps Disposal
• Razor blades, lancets, and other sharp objects must be placed in a puncture-resistant sharps container (biohazard container)
• Prevents injury and contamination
• Never place sharps in regular trash
---
Soiled Linen Storage
• Soiled towels and capes must be stored in a closed, covered container
• Must be separate from clean linens
• Must be laundered before reuse
---
Contact Dermatitis
• Contact dermatitis – Skin inflammation caused by direct contact with irritants or allergens (chemicals, latex, color products)
• A leading occupational hazard for cosmetologists
• Prevention strategies:
- Wear protective gloves
- Use barrier creams
- Switch to non-latex alternatives if latex sensitivity develops
- Limit prolonged exposure to water and chemicals
---
Hand Washing – The First Line of Defense
The FIRST step before any service: Wash hands thoroughly with soap and water
Also wash hands:
• After removing gloves
• After handling chemicals
• After contact with bodily fluids
• After using the restroom
---
Key Terms – Salon Safety
• Fomite – Inanimate object that transfers pathogens
• Sharps container – Puncture-resistant biohazard disposal container for needles and blades
• Contact dermatitis – Skin inflammation from chemical/allergen contact
• Blood exposure protocol – Step-by-step procedure for managing blood incidents
• Single-use items – Items that cannot be disinfected; must be discarded after one use
---
Illinois State Board Regulations
Implement Storage After Disinfection
• After disinfection, implements must be stored in a clean, covered container or sealed bag
• Prevents recontamination before next use
Required Salon Posting
• The salon's Illinois cosmetology establishment license must be posted in a visible location accessible to clients at all times
EPA-Registered Disinfectants
