CHAPTER 1 — INFECTION CONTROL, SAFETY & SANITATION

Louisville Beauty Academy (LBA) — YES I CAN™ Licensing Foundations

In beauty licensing across the United States, Infection Control is the #1 tested topic.
Every state board, including PSI/NIC-based exams, places the highest emphasis on safety because nail technicians work directly with the skin, nails, and sometimes blood exposure.

Louisville Beauty Academy teaches this first because a safe nail technician is a professional nail technician.
This chapter is designed to give you complete confidence, even if English is not your first language.

Take your time.
Breathe.
LBA believes in you.
YES YOU CAN.

📘 1. Understanding Infection Control

“Infection Control” means preventing the spread of harmful microorganisms in the salon.

There are 3 levels of control:

1. Sanitation (Cleaning)

Removing visible dirt and debris.
Lowest level of infection control.
Examples:

• washing hands
• using soap and water
• brushing debris off tools

2. Disinfection

Destroying most microorganisms on non-porous surfaces.
Required by law in every salon.
Examples:

• EPA-registered disinfectants
• 70% alcohol
• quats

3. Sterilization

Destroying all microbial life, including spores.
Only required for:

• invasive tools
• medical-grade implements
  Some salons use autoclaves, but not all states require them.

Louisville Beauty Academy trains students to know the legal requirement in their state and also teaches higher standards to keep clients safe.

---

📘 2. Types of Microorganisms (What Causes Infection)

Bacteria

Single-celled organisms.
Two main types:

• Nonpathogenic (good)
• Pathogenic (harmful)

Viruses

Smaller than bacteria.
Preventable through sanitation and disinfection, not curable by antibiotics.

Fungi

Causes nail infections like onychomycosis.

Parasites

Organisms living on a host.

Bloodborne Pathogens

Diseases transmitted through blood, such as:

• Hepatitis B
• Hepatitis C
• HIV

LBA teaches the standard rule:

“Treat all blood as infectious — always use universal precautions.”

---

📘 3. Universal Precautions (Required Practice for All Nail Technicians)

Universal Precautions means treating every client as if they could transmit infection.
This is required by OSHA and tested in all licensing exams.

Standard behaviors include:

• wearing gloves when needed
• washing hands before each service
• disinfecting surfaces before and after clients
• using clean tools
• never reusing single-use items
• following blood exposure protocol

Louisville Beauty Academy reminds every student:
Safety first. Beauty second.

---

📘 4. Tools: Single-Use vs Reusable

Single-Use (Disposable)

Used one time, then thrown away.
Examples:

• wooden sticks
• nail files
• buffers
• cotton
• toe separators
• sanding bands

Reusable (Multi-Use)

Must be cleaned and disinfected after every client.
Examples:

• nippers
• cuticle pushers
• metal files
• clippers

Louisville Beauty Academy requires students to separate these items in their kits clearly.

---

📘 5. Proper Disinfection at LBA (Step-by-Step)

Every LBA student follows this universal procedure:

1. Clean

• Scrub tool with soap and warm water
• Remove visible debris

2. Rinse

• Rinse thoroughly

3. Dry

• Dry completely (wet tools weaken disinfectant)

4. Immerse

• Place tool fully submerged in EPA-registered disinfectant
• Follow manufacturer contact time (often 10 minutes)

5. Rinse & Store

• Rinse with water
• Dry completely
• Store in a clean, closed container

Louisville Beauty Academy teaches this routine until it becomes second nature.

---

📘 6. Blood Exposure Procedure (PSI/NIC Style)

Every state board tests this.

If blood appears:

1. Stop the service immediately.
2. Wash your hands and put on gloves.
3. Clean the injury with antiseptic.
4. Bandage the area.
5. Dispose of contaminated items in a sealed bag.
6. Disinfect the workstation.
7. Wash hands again.
8. Record the incident if required.

Louisville Beauty Academy emphasizes calm, clean, confident actions.

---

📘 7. Safety Data Sheets (SDS)

Every chemical used in the salon must have an SDS.
It explains:

• ingredients
• fire hazard
• storage
• safe use
• first-aid steps

LBA trains students to understand SDS because it protects both technician and client.

---

📘 8. Handwashing — The Most Powerful Tool

Louisville Beauty Academy repeats this daily:
“Handwashing prevents more disease than any chemical.”

Proper steps:

1. Wet hands
2. Apply soap
3. Scrub for 20 seconds
4. Clean nails and between fingers
5. Rinse
6. Dry with clean towel
7. Turn off faucet with towel
