Infection Control and Sanitation in Cosmetology
Sanitation, Cleaning, Sanitizing, Disinfecting, and Sterilizing
There are important differences among terms used in the salon: cleaning, sanitizing, disinfecting, and sterilizing. Cleaning = removal of garbage/debris; sanitizing = chemical process to reduce disease-causing germs on cleaned surfaces to safe levels; disinfecting = chemical process to destroy harmful organisms on environmental surfaces; sterilizing = destroys all microbial life, and is rarely mandated in typical salon settings.
Sanitation is not simply a synonym for cleaning; items can be cleaned but not sanitized.
Hospital disinfectants (EPA-registered) are designed for nonporous surfaces and are used to control the spread of disease in noncritical, noninvasive environments.
Terminology reminder in practice: consistently distinguish between cleaning, sanitizing, disinfecting, and sterilizing to avoid under- or over-application of products.
Practical Scenario: Sanitation in a Salon
New employee tasked with cleaning and disinfecting counters, workstations, tools, implements, and pedicure equipment; must log cleaning/disinfection information in the salon logbook.
Logbooks and record-keeping are essential for compliance and for state board inspections.
Infection Control Principles for Cosmetologists
Cosmetologists must study and understand infection control principles and practices to be knowledgeable, successful, and responsible.
Understand illness-causing pathogens you may encounter in the salon and how cleaning and disinfecting, along with federal and state rules, protect you and clients.
Knowledge of cleaning/disinfecting products and correct usage helps protect the salon environment from pathogens and their modes of transmission.
Compliance with federal, state, and local laws reduces the risk of costly safety violations.
State boards may inspect the salon; poor cleanliness/disinfection can lead to write-ups that affect licensing and practical exams.
Labels, Safety Data Sheets, and Chemical Safety
MSDS (Material Safety Data Sheets) used to be the standard; now commonly SDS is used; keep the chemical safety information available and consult it.
SDS sections typically include: Identification, Hazard Identification, Composition/Ingredients, First Aid Measures, Firefighting Measures, Accidental Release Measures, Handling and Storage, Exposure Controls/Personal Protection (PPE), Physical/Chemical Properties, Toxicology, Ecological Information, Regulatory Information, and Revision Data.
Important symbols on product labels indicate hazards (e.g., health hazard, exclamation mark, acute toxicity, flammable).
OSHA regulations require that employees read the SDS and sign off to confirm they have read it.
Safety Data Sheets (SDS) in Practice
Big yellow SDS binders in salons contain safety protocols for chemicals used (bleach, sanitizers, hair color, etc.).
SDS helps determine what to do if there is skin contact, inhalation, ingestion, or other exposure.
Hospital Disinfectants and EPA Registration
Hospital disinfectants are EPA-registered products effective on nonporous surfaces and suitable for hospital-level disinfection in salons.
Quaternary ammonium compounds (quats) are a common class of EPA hospital disinfectants used in salons; designed for nonporous surfaces.
Tuberculosis-disinfectants are formulated to kill Mycobacterium tuberculosis in addition to other pathogens.
Nonporous surface means surfaces without pores (e.g., many countertops and metal tools); porous surfaces (e.g., some wood, fabric) require different handling.
Laws, Rules, and Regulations
Laws are broad legal requirements; rules are specific standards of conduct written by a regulatory agency (state board).
Rules can be updated frequently; cosmetologists must stay aware of and comply with changes.
Example: State agencies may revise acceptable disinfectants (e.g., EPA vs alternative sanitizers) and require adherence to updated rules.
Licensure and regulation communications (e.g., emails about revisions) are routine; staying informed is essential.
Pathogeny and Infectious Diseases in the Salon
Four main types of microorganisms to understand: bacteria, viruses, fungi, and parasites.
An infectious disease is caused by pathogens that can spread from person to person.
Cleaning is mechanical (soap/detergent + water) to remove visible dirt and germs; disinfection is chemical and destroys most but not all pathogens on surfaces.
Disinfectants must be used according to label instructions, including mixing ratios and required contact time.
Disinfection is not effective against bacterial spores in some cases; sterilization is needed to destroy all microbial life in other contexts.
Prevention hinges on proper procedures and adherence to guidelines.
Bloodborne Pathogens and Related Diseases
Bloodborne pathogens are microorganisms carried in blood or body fluids (e.g., hepatitis and HIV/AIDS).
Transmission in the salon can occur via cuts or broken skin during services; avoid cutting living skin (a medical procedure outside cosmetology scope).
Hepatitis: a bloodborne virus that damages the liver; three types of concern: A, B, C. Hepatitis B is particularly hard to kill on surfaces; verify disinfectant efficacy against HBV on the label.
HIV/AIDS: virus that weakens the immune system.
Proper cleaning/disinfection of surfaces and tools reduces transmission risk.
Hepatitis, HIV, and Other Infectious Agents
Hepatitis A, B, C: different transmission modes and surface survivability; HBV is the most challenging to inactivate on surfaces.
HIV: spread primarily through blood and certain bodily fluids; transmission in salons is minimized by proper infection control.
Fungi and Parasites
Fungi include mold, mildew, yeast; can cause infections like ringworm if proper disinfection fails.
Parasites require a host to survive; can be internal (foodborne) or external (ticks, fleas, head lice).
Pediculosis capitis (head lice) and scabies are contagious; scalp checks are essential before services.
Pedicures and foot treatments must be careful to prevent cross-contamination; use proper disinfection of pedicure bowls and implements.
Scalp Checks, Lice, and Client Readiness
Perform a thorough scalp check before services to detect lice or other conditions.
If a client has head lice, you cannot service them that day; provide guidance for home treatments and break contact until cleared.
After treating or identifying issues, sanitize station and implements thoroughly before serving next client.
Decontamination, Cleaning, and Disinfection Procedures
Decontamination refers to removal of blood and potentially infectious materials and visible debris.
Step 1: Cleaning with soap/detergent and water; remove visible debris from tools/implements.
Step 2: Disinfection on nonporous surfaces using EPA-registered products; ensure products are used according to label instructions and are appropriate for the surface/material.
Never use household cleaners as hand cleansers; they can cause irritation.
If a disinfectant appears dirty or contaminated, replace it.
Bleach cautions: can corrode metals/plastics and irritate skin/eyes; not recommended for all salon tools; mix fresh every or when contaminated; store away from heat/light.
For diluting disinfectants, add the disinfectant to water (not water to disinfectant).
Wear PPE (gloves, safety glasses); use tongs to remove items from disinfectants; keep disinfectants out of reach of children.
If disinfectant becomes visibly dirty, change the solution.
Disinfectants should be prepared and used strictly according to the label; ensure contact time is observed (the surface must remain visibly wet for the recommended duration).
Tools: multiuse (reusable) vs single-use (disposable).
Multiuse examples: nippers, shears, cones, metal pushers, rollers, permanent wave rods; must have hard, nonporous surfaces.
Single-use examples: wooden sticks, cotton balls, sponges, gauze, tips, nail files, buffers; disposed after a single use.
Handling towels, linens, and capes: use for each client; laundered per label instructions; hot water and appropriate detergents (Texas state standards noted in the transcript).
Note about pedicure chairs that circulate water: cleanliness importance to prevent cross-contamination.
Cleaning Towels, Linens, and Linens Laundering
Launder towels, linens, and capes between clients; wash per label directions; hot water and bleach are common in salon protocols.
First Aid and Exposure Incidents
If a cut occurs during service: stop service, inform client, call for assistance if needed; have a first aid kit with bandages and wipes ready.
Don gloves if assisting with exposure management; wash injury with soap and water; apply firm pressure with a cotton gauze to stop bleeding; cleanse area with antiseptic.
Apply adhesive bandage after cleaning and covering the wound; return to service area with gloves; isolate contaminated tools/items in a dirty item container.
If a surface is contaminated, disinfect with appropriate product and allow contact time; dispose of single-use contaminated items (wipes, cotton balls, gloves) in a plastic bag and place bag in a closed trash container with a liner.
Dispose of sharps in a sharps container according to local/state laws.
After service, thoroughly clean and disinfect all tools/implements used; submerge in EPA-registered hospital-grade disinfectant for at least .
If any signs of redness, swelling, pain, or irritation appear post-service, seek medical advice.
