2.4 Chemical Safety, SDS, Ventilation & Bloodborne Pathogens

Labeling & Storing Chemical Products

A nail salon stocks dozens of chemical products: acrylic monomer (liquid acrylic), polymer powders, UV gels, polish removers (acetone and non-acetone), adhesives, disinfectants, cuticle removers, and callus products. Each one carries specific hazards if mislabeled or mis-stored.

Labeling Rules

• Keep every product in its original, manufacturer-labeled container. NAC 644A.755(8) requires that all bottles and containers be distinctly and correctly marked with a label which discloses its contents, and that all articles containing poisonous substances be distinctly marked as such.
• Never transfer a chemical into an unlabeled bottle or food container — a client or technician could mistake it for something safe.
• If a smaller working container is needed (a pump dispenser for remover), it must be labeled with the product name and hazard warning. For a disinfectant concentrate moved out of its original container, NAC 644A.740 additionally requires the label to carry the name of the disinfectant and its use instructions.
• NAC 644A.800 prohibits an establishment from having on its premises any cosmetic product containing a hazardous substance banned by the FDA for use in cosmetic products, or from using a cosmetic product in a manner the FDA has not approved. NAC 644A.805 separately bans methyl methacrylate (MMA) liquid monomers, fumigants, and formalin tablets or liquids from the licensed areas of an establishment.
• Labels must remain legible — replace a label that has dissolved or smeared.
• Never mix products unless the manufacturer instructions explicitly allow it; mixing certain disinfectants (e.g., bleach and ammonia) releases toxic gas.

Storage Rules

• Store away from heat, sparks, and open flame — acrylic monomer and acetone are flammable.
• Keep containers closed when not in use to limit vapor release.
• Store out of client reach, preferably in a closed cabinet.
• Keep disinfectants separate from other chemicals to avoid accidental mixing.
• Store heavier and larger containers on lower shelves to prevent falls.
• Keep a current inventory so expired products can be discarded.

Safety Data Sheets (SDS) — Formerly MSDS

A Safety Data Sheet (SDS) — previously called Material Safety Data Sheet (MSDS) — is the manufacturer's document that tells you everything you need to handle, store, and respond to a chemical safely. OSHA's Hazard Communication Standard requires employers to maintain an SDS for every hazardous chemical in the workplace and to make them accessible to all employees.

Where Are SDS Kept? — the Nevada Rule

NAC 644A.755(9) states it plainly: "Readily accessible safety data sheets for each product used in the cosmetological establishment containing hazardous substances must be available to all licensees within the establishment at all times."

In practice that means:

• A binder or electronic file reachable by every licensee, not just management, at all times — not "during office hours."
• Current sheets; replace them when a product is reformulated or switched.
• New products get their SDS filed before the product touches a client.

A missing SDS is a common inspection finding, and because NAC 644A.755 sits inside NAC 644A.705 to 644A.770, NAC 644A.860 sets a $100 fine per violation unless the Executive Director sends it to a disciplinary hearing instead.

The 16 Standard SDS Sections

SDS follow a globally harmonized 16-section format. The exam most often tests the first four:

For the exam, know that Section 4 (first-aid) is what you consult immediately after an exposure, and Section 8 (exposure controls / PPE) tells you what gloves and ventilation a product requires.

Ventilation for Nail Dust & Vapors

Filing natural and acrylic nails produces fine particulate dust that can irritate the respiratory tract and carry microbial contaminants. Acrylic monomer, polish remover, and adhesives release volatile organic compound (VOC) vapors that cause headaches, dizziness, and with chronic overexposure, sensitization or respiratory effects.

Ventilation Requirements

NAC 644A.710 requires each cosmetological establishment and school of cosmetology — and each room or residence used as one — to have a mechanical system for exhaust acceptable to the Board, complying with all applicable building codes, local ordinances and fire codes, the Nevada Occupational Safety and Health Act, and the federal Occupational Safety and Health Act of 1970, as amended. Restrooms have their own requirement under NAC 644A.715 for a mechanical exhaust system that completely circulates the air.

Beyond the mandated building exhaust, nail-specific practice adds:

• General (dilution) ventilation: a salon-wide HVAC system that exchanges indoor air with filtered outdoor air.
• Source-capture (local exhaust) ventilation: a table-level dust collector or extraction hose positioned within inches of the filing point to capture dust and vapors at their source before they reach the breathing zone.
• Source capture is more effective than general ventilation alone because it removes the contaminant before it spreads.
• Keep acrylic liquid containers closed when not actively using.
• Avoid over-applying polish remover; use pump dispensers.
• Consider a dust mask (N95) for the technician during heavy acrylic filing — not a substitute for ventilation, but an additional protection.

Note the boundary carefully: the mechanical exhaust system is a facility requirement under NAC 644A.710, enforced through establishment inspection. A table-level dust collector is best practice, not a Nevada mandate, and the Nevada nail practical does not include a ventilation task — its four segments are basic set-up, gel manicure, nail enhancements, and the blood exposure procedure.

Salon Accident Prevention

Beyond chemicals and ventilation, general accident-prevention habits protect clients and staff:

• Keep walkways clear of cords, bags, and spilled product.
• Wipe spills immediately — a wet floor is a slip hazard.
• Tape or cover electrical cords crossing walkways.
• Inspect electric file cords and plugs for fraying; replace damaged equipment.
• Keep hot tools (paraffin warmers, UV/LED lamps) away from flammable products.
• Do not overload electrical outlets.
• Maintain a first-aid kit in the salon.
• Post emergency phone numbers and the salon address near the phone.

Bloodborne Pathogens & the Blood-Exposure Procedure

Bloodborne pathogens are microorganisms in blood that can cause disease — chiefly hepatitis B virus (HBV), hepatitis C virus (HCV), and human immunodeficiency virus (HIV). In a nail salon, exposure happens when a nipper, scissors, or file accidentally cuts the client's skin, or when a technician cuts their own skin on a contaminated implement.

The Written Exposure Plan

Salons must maintain a written bloodborne pathogen exposure-control plan that includes:

• A statement of universal precautions.
• The personal protective equipment (PPE) provided (gloves, etc.).
• The step-by-step blood-exposure procedure.
• Post-exposure steps (washing, recording the incident, medical follow-up).
• Training records for staff.

The Blood-Exposure Procedure (Step by Step)

Nevada anchors the disposal half of this procedure in NAC 644A.705: any disposable material that contacts blood or other bodily fluids must be disposed of in a sealable plastic bag or in a manner that protects the licensee, the client, and anyone who may later handle the waste such as sanitation workers; and any disposable sharp object that contacts blood or bodily fluids must go into a sealable rigid container strong enough to prevent accidental cuts or punctures. Regardless of blood exposure, disposable sharp objects including blades, needles, and lancets must be disposed of in labeled sharps containers.

NAC 644A.780 sets the service boundary: a licensee shall not perform any service upon a surface of the skin where such skin is inflamed, infected, broken or otherwise compromised, and shall not perform any service on a client whose skin shows signs of secretion of any bodily fluids. Once a cut bleeds, the service stops — that is a regulation, not a courtesy.

The Nevada practical grades a dedicated Blood Exposure Procedure segment (Section 6.4), and the written exam tests the sequence:

1. Stop the service immediately. Do not continue filing around an open cut.
2. Put on clean single-use gloves before touching the area.
3. Apply pressure with a clean cotton swab or sterile gauze to stop bleeding. Never use your bare fingers.
4. Clean the area with antiseptic; offer the client a bandage.
5. Discard all single-use items that contacted blood (cotton swab, file, buffer, orangewood stick) into a closed receptacle.
6. Clean, then disinfect any multi-use implement that contacted blood with an EPA-registered hospital disinfectant (a tuberculocidal or bloodborne-pathogen–effective product) for the full contact time.
7. Clean and disinfect the work surface area around the exposure.
8. Remove gloves and wash hands thoroughly.
9. Record the incident in the salon log; advise the client to seek medical follow-up if needed.

Critical Don'ts

• Never continue the service after a blood exposure without completing the procedure.
• Never squeeze a cut to “bleed it out” — that is not evidence-based practice.
• Never apply a disinfectant directly to the client's open wound — disinfectants are for surfaces and implements, not skin.
• Never reuse a file, buffer, or orangewood stick that touched blood.

Takeaways for the Exam

• Original labeled containers, flammables away from heat, never mix products.
• SDS for every product, accessible to staff, Section 4 = first-aid, Section 8 = PPE/ventilation.
• Source-capture ventilation at the table beats general ventilation alone.
• Written bloodborne pathogen exposure plan is required.
• Blood-exposure procedure: stop, glove, control bleeding, clean, disinfect, bandage, discard, wash hands, record — in that order.
