Infection Control & Safety
101 questionsSterilization destroys all microbial life, including resistant bacterial spores. It is the highest level of decontamination and is used in surgical settings, not in salon practice.
16 CCR §979Any bleeding triggers the bloodborne pathogen protocol: stop, glove up, apply pressure with a clean cotton ball or sterile gauze, and disinfect any tool that contacted blood with an EPA-registered tuberculocidal disinfectant.
16 CCR §979California requires full immersion in an EPA-registered disinfectant for the labeled contact time, with a minimum of 10 minutes. UV cabinets, hot water alone, and salon sterilization are NOT required and not substitutes for proper chemical disinfection.
16 CCR §979Local exhaust ventilation pulls vapors and dust away from the worker's breathing zone, reducing chronic inhalation exposure. Masking odors or sealing the salon does not protect respiratory health.
16 CCR §979Client intake screening is required for the safety of staff, equipment, and other clients. If a contagious condition is suspected and the client will not disclose, the technician should decline service and refer the client to a physician.
16 CCR §979Ethyl methacrylate (EMA) is the legal monomer used in professional acrylic nail systems in California. MMA is prohibited; methylene chloride and toluene are not used as nail monomers.
BPC §7315California regulation requires chemical disinfection in an EPA-registered product for the labeled contact time. A UV cabinet may be useful for keeping already-disinfected tools clean, but it does NOT replace the chemical disinfection step.
16 CCR §979Inspectors look for an EPA registration number on the label and confirmation that the product is bactericidal, virucidal, and fungicidal. 'Natural' or 'green' marketing without these specifics does not meet the requirement.
16 CCR §979Multi-use plastic clipper guards must be pre-cleaned (hair brushed/washed out), then disinfected for the full contact time. They are not single-use, and soaking in soapy water alone does not disinfect.
16 CCR §979Infection control violations are the most common reason BBC inspectors issue citations, and they pose the greatest risk of harm to the public. The exam weights the topic at approximately 25% to reflect this importance.
16 CCR §97916 CCR §980 requires the work area, including floors, to be kept clean and free of hair, debris, and waste during business hours, not just at closing.
16 CCR §98016 CCR §981 mandates that multi-use implements be cleaned with soap or detergent and water to remove all visible debris before any disinfection step; disinfectant cannot work through residue.
16 CCR §98116 CCR §982, together with Cal/OSHA 8 CCR §5193, requires that materials contaminated with blood or OPIM be placed in closeable, leak-proof, biohazard-labeled containers and disposed of as regulated medical waste.
16 CCR §98216 CCR §983 requires that multi-use linens and towels be laundered after each client with detergent and stored clean in a covered or closed container, separate from soiled items.
16 CCR §98316 CCR §984 and Cal/OSHA 8 CCR §5193 require single-use needles and other sharps to be discarded immediately into a closable, puncture-resistant, leak-proof sharps container labeled as biohazard, located at the point of use. Recapping is prohibited.
16 CCR §984Per 16 CCR §979, the disinfectant must be EPA-registered as a hospital-grade, broad-spectrum product effective against bacteria, viruses, and fungi when used on non-porous tools.
16 CCR §979California BBC foot-spa cleaning protocol requires the basic Phase A clean-and-disinfect after every client, plus a more thorough Phase B weekly cleaning that removes the screen/filter and circulates disinfectant through jets/inlets.
16 CCR §979Per 16 CCR §979, wet disinfectant solutions must be changed daily and immediately if visibly soiled or contaminated, to maintain the labeled antimicrobial potency.
16 CCR §979Sterilization destroys all forms of microbial life, including resistant bacterial spores, typically via autoclave. High-level chemical disinfection kills most pathogens (bacteria, viruses, fungi, TB) but is not guaranteed sporicidal. Salons routinely use disinfection, not sterilization.
16 CCR §979Standard household bleach is ~5.25% sodium hypochlorite (~52,500 ppm). A 1:10 dilution (10% bleach) yields roughly 5,000 ppm available chlorine, the level recommended for disinfecting blood spills.
HBV is significantly hardier than HIV: it can survive on environmental surfaces in dried blood for at least 7 days and is more resistant to heat and chemicals, which is why salon disinfectants must be specifically labeled effective against HBV.
Mycobacterium tuberculosis has a waxy lipid cell wall that is hard to penetrate. A product that kills TB is considered an intermediate- to high-level disinfectant and a reliable indicator of broad-spectrum efficacy, which is why the BBC requires it on non-porous implements.
16 CCR §97916 CCR §979(c), reinforced by BPC §7315, prohibits the use of MMA monomer for natural-nail enhancements because of its strong bond, brittleness, and link to nail-plate injury and allergic reactions. Ethyl methacrylate (EMA) is the lawful substitute.
16 CCR §979(c) / BPC §7315Standard Precautions (Cal/OSHA 8 CCR §5193) treat all blood and OPIM from every person as potentially infectious, regardless of perceived risk. This is broader than the older Universal Precautions, which focused on blood-borne pathogens only.
Cal/OSHA 8 CCR §5193Cal/OSHA §1532.1 limits occupational lead exposure. While lead is not an approved cosmetic ingredient, trace contaminants can appear in imported pigments, decorations, or older inventory; employers must control exposure below the permissible exposure limit.
Cal/OSHA 8 CCR §1532.1Quat concentrates are commonly labeled around 1:200 (often ~0.5 oz per gallon of water). California regulations require following the manufacturer's label directions exactly, which take legal precedence over generic ratios.
16 CCR §979California regulations under §979 expect licensees to maintain dated logs of cleaning/disinfection events (especially foot-spa Phase A/B and sterilization equipment) for at least 30 days, available to BBC inspectors on request.
16 CCR §979Per Cal/OSHA §5193 exposure-control procedure and BBC infection-control rules, the licensee must don gloves, control bleeding, clean and disinfect contaminated surfaces, discard contaminated single-use items into biohazard waste, and disinfect any reusable implements before reuse.
16 CCR §979Although salons are not HIPAA-covered entities, client intake disclosures about medical conditions, medications, allergies, or pregnancy are private information. California consumer-protection principles and standard professional ethics require keeping such disclosures confidential.
Per 16 CCR §979, only EPA-registered, hospital-grade liquid disinfectants meet the legal requirement. UV cabinets are not approved disinfectants because uneven exposure and lack of contact penetration prevent reliable kill rates; they may only be used as clean storage.
16 CCR §979§5194 (HazCom) requires employers to keep a current Safety Data Sheet (SDS) for every hazardous chemical onsite and to make it readily accessible to employees during all work shifts, along with employee training.
Cal/OSHA 8 CCR §5194Per 16 CCR §979, porous single-use items cannot be effectively disinfected and must be discarded after a single client. Reusing porous items between clients is a common citation.
16 CCR §979Engineering controls remove or reduce a hazard at its source (e.g., source-capture ventilation, ventilated nail tables). They sit above administrative controls and PPE in the hierarchy of controls because they do not depend on worker behavior.
16 CCR §979 requires the licensee to follow the manufacturer's label directions, including the EPA-approved contact (dwell) time. Contact time varies by product (commonly 1, 5, or 10 minutes), and tools must remain fully submerged for that period.
16 CCR §979When implements are contaminated with blood or OPIM, 16 CCR §979/§982 and Cal/OSHA §5193 require the licensee to first clean visible debris, then disinfect with an EPA-registered product that carries a tuberculocidal and bloodborne-pathogen claim for the full labeled contact time.
16 CCR §979 / §982Universal Precautions, codified for California workers in Cal/OSHA §5193 (the Bloodborne Pathogens standard), require that ALL human blood and certain body fluids be treated as if infectious for HIV, hepatitis B, hepatitis C, and other bloodborne pathogens, regardless of what the client discloses. This is because many infected clients are asymptomatic and do not know their status, and a 'risk-rank-then-glove' approach is unsafe. Option C relies on disclosure that often is not available. Option B is discriminatory and not the rule. Option D ignores the standard's plain text, which covers worker exposure to client material.
Cal/OSHA §5193California requires that disinfectants used on non-porous multi-use salon tools between clients be EPA-registered and labeled as hospital-grade, meaning effective against bacteria, viruses, and fungi, and additionally tuberculocidal as a proxy for activity against tough bloodborne pathogens. The product must be used at the label dilution and for the full label contact time. This standard is set under CCR Title 16 §979 and reinforced in BBC inspection practice. Household vinegar (option B) is not EPA-registered as a hospital-grade disinfectant. Plain boiling water (option C) is not disinfection as defined for salons. Perfume or hairspray (option D) is not a registered disinfectant and contains additives that interfere with surface contact.
CCR Title 16 §979The Cal/OSHA Bloodborne Pathogens standard (§5193) requires every workplace with reasonably anticipated occupational exposure to have an Exposure Control Plan that includes immediate care and reporting of any exposure incident. The correct steps for the worker are to wash the exposed skin with soap and water (or flush eyes/mucous membranes with water), report the exposure promptly to the employer, document the source if known, and obtain post-exposure medical evaluation and follow-up including baseline testing and any indicated prophylaxis (such as HBV vaccination boost or HIV PEP when warranted). Options A, C, and D ignore the standard, harm the worker, and create medical and legal liability.
Cal/OSHA §5193California's standard for between-client decontamination of non-porous multi-use implements is CLEAN (debris removed) plus DISINFECT (EPA-registered hospital-grade product effective against bacteria, viruses, and fungi, used at label dilution and full label contact time). UV cabinets do not reliably disinfect; they kill some surface organisms in line-of-sight but cannot penetrate hinges, joints, or shadows, so they are acceptable only as clean storage after proper chemical disinfection. Autoclaves (steam under pressure) achieve sterilization, exceeding the BBC's disinfection requirement, but are not required. The CCR Title 16 §979 sanitation rules underpin BBC inspection practice. A quick alcohol wipe is not equivalent.
CCR Title 16 §979Contact time on an EPA label is the MINIMUM time the surface must remain visibly wet with disinfectant at the labeled dilution to achieve the kill claim. Any deviation (shorter time, wrong dilution, partial immersion, soiled solution, uncovered jar that allows evaporation) invalidates the manufacturer's tested efficacy. California licensees must clean implements first (debris physically removed) THEN disinfect, and change the solution at least daily or whenever visibly contaminated, per CCR Title 16 §979 and BBC sanitation practice. Options A, B, and D each break a specific rule and produce a non-compliant cycle that an inspector will cite.
CCR Title 16 §979The Cal/OSHA Bloodborne Pathogens standard (§5193) requires every workplace with reasonably anticipated occupational exposure to maintain a written Exposure Control Plan and to follow a defined cleanup procedure for blood and OPIM spills: don gloves, contain and absorb, clean visible blood, disinfect with an EPA-registered tuberculocidal/hospital-grade disinfectant for the labeled contact time, dispose of blood-saturated disposables in a labeled biohazard container, doff gloves, wash hands, and document. Option C skips disinfection. Option B is excessive, off-target, and damages flooring without controlling the spill. Option D is unprofessional and unsafe; the employer is responsible for the cleanup procedure, not the client.
Cal/OSHA §5193Porous items (emery boards, wooden orangewood sticks, buffer blocks, cotton, gauze, paper applicators) absorb fluids and dust into their structure and cannot be reliably disinfected; California treats them as SINGLE-USE and they must be discarded after one client. Non-porous, multi-use items (metal cuticle pushers, nippers, combs, shears) must be cleaned of debris and immersed in an EPA-registered hospital-grade disinfectant for the labeled contact time, then dried and stored in a clean closed container. This is the core of CCR Title 16 §979 sanitation. Options A, B, and C either reuse a porous item, discard a reusable one, or mis-classify the metal tool.
CCR Title 16 §979Whirlpool foot spas have generated some of the most serious salon outbreaks documented in California (Mycobacterium fortuitum boils, etc.) precisely because biofilm forms in the jets and screens. The BBC pedicure-equipment rules (CCR Title 16 §980.4) require a between-client procedure (drain, clean, refill with disinfectant, circulate for label contact time, rinse), a more rigorous end-of-day procedure, a weekly removal-and-cleaning of the screen/filter, and a written log signed by the licensee. Options B, C, and D miss steps and intervals and would fail an inspection and put clients at risk.
CCR Title 16 §980.4Ethics & California Law
70 questionsThe Board of Barbering and Cosmetology (BBC) is established under the Department of Consumer Affairs and is the single state body that licenses and regulates beauty professionals and establishments in California.
BPC §7303Under BPC §7316, an esthetician license covers skin care, waxing, and non-invasive facial treatments. Cutting or trimming hair is not within the esthetician scope and would constitute practicing outside the license.
BPC §7316Laser hair removal involves a medical device that penetrates the skin and is considered a medical procedure in California. It must be performed by or under the supervision of a licensed physician and is outside every BBC license, including a full cosmetologist.
BPC §7316Botox and other injectable treatments penetrate the skin and are medical procedures. Only licensed medical professionals may inject. Performing injectables under a BBC license is practicing outside scope and unauthorized practice of medicine.
BPC §7316A manicurist license is limited to care of the nails and the hands and feet up to and including the elbow and knee. Facials, waxing, and hair cutting are outside the manicurist scope.
BPC §7316California created the Hairstylist license effective 2023. It allows cutting, styling, coloring, and chemical hair services but does not include skin care or nail services.
BPC §7316In California, the barber scope of practice covers cutting, styling, shaving, and chemical hair services including color and perms. The license is not restricted to one gender.
