3.3 OSHA, FDA & EPA: Safety Agencies, Hazard Communication & Safety Data Sheets

3.3 OSHA, FDA & EPA: Safety Agencies, Hazard Communication & Safety Data Sheets

Quick Answer: The Occupational Safety and Health Administration (OSHA) enforces federal workplace health and safety standards. OSHA's Hazard Communication Standard (HCS) is aligned with the Globally Harmonized System (GHS), establishing standardized 16-section Safety Data Sheets (SDSs), chemical hazard warning labels, and 9 universal pictograms. Salon owners must maintain accessible SDS documentation for every chemical product in the salon, provide personal protective equipment (PPE), and ensure adequate chemical ventilation.

OSHA Authority & Salon Workplace Jurisdiction

The Occupational Safety and Health Administration (OSHA) is a federal agency established by Congress under the Department of Labor through the Occupational Safety and Health Act of 1970. OSHA's statutory mission is to ensure safe and healthful working conditions for working men and women by setting and enforcing standards, and by providing training, outreach, education, and assistance.

In the cosmetology industry, OSHA possesses legal jurisdiction over commercial salons, barbershops, and spas that employ workers. While state licensing boards (such as the Minnesota Board of Cosmetology) focus primarily on consumer protection, sanitary facilities, and professional competence, OSHA enforces standards protecting workers from workplace hazards, including:

• Exposure to toxic, flammable, or caustic chemicals.
• Bloodborne pathogen exposure risks.
• Physical workplace hazards (ergonomics, slippery floors, fire exits, electrical wiring).
• Inadequate ventilation and respiratory hazards.

OSHA safety compliance officers have the legal authority to conduct unannounced workplace inspections, issue citations for safety violations, and assess civil penalties against salon employers.

The Hazard Communication Standard (HCS) & the GHS

Salons store and use hundreds of chemical compounds: hair lighteners, hydrogen peroxide developers, permanent wave waving lotions, sodium hydroxide relaxers, acetone, alcohol, chemical peels, and monomer liquids. In 1983, OSHA enacted the Hazard Communication Standard (HCS) (29 CFR 1910.1200), historically known as the "Worker Right-to-Know Law." This standard established that employees have both a need and a right to know the identities and hazards of the chemicals they are exposed to in the workplace.

The Shift to the Globally Harmonized System (GHS)

In 2012, OSHA officially updated the Hazard Communication Standard to align with the United Nations' Globally Harmonized System of Classification and Labeling of Chemicals (GHS). This historic revision transitioned the standard from the "Right to Know" to the "Right to Understand."

The GHS established an internationally uniform approach to chemical safety, replacing inconsistent national labels with:

1. Standardized Hazard Classifications: Specific criteria for physical hazards (flammability, reactivity) and health hazards (toxicity, carcinogenicity, skin corrosion).
2. Standardized Container Labels: Mandated chemical container labeling elements:
   • Product Identifier: Chemical name or trade code.
   • Signal Words: Exactly two standardized signal words indicate hazard severity:
     • "DANGER" is reserved for severe, life-threatening hazards.
     • "WARNING" is used for moderate or less severe hazards.
   • Hazard Statements: Standardized phrases describing the exact nature of the hazard (e.g., "Highly flammable liquid and vapor," "Causes severe skin burns and eye damage").
   • Precautionary Statements: Specific instructions covering prevention, response, storage, and disposal.
   • GHS Hazard Pictograms: Standardized universal graphic symbols.

The 9 GHS Universal Hazard Pictograms

GHS hazard pictograms consist of a distinct black symbol set on a white background within a square set on a point (red diamond border). There are nine universal pictograms; OSHA enforces eight (the environmental pictogram is non-mandatory under OSHA, as environmental impact falls under EPA jurisdiction):

1. Health Hazard: Depicts a human silhouette with a six-pointed star burst across the chest. Identifies carcinogens, respiratory sensitizers, reproductive toxicity, target organ toxicity, mutagenicity, and aspiration hazards. (Common in salons: hair smoothing formulas containing formaldehyde, methylene glycol).
2. Flame: Depicts an open flame. Identifies flammable gases, aerosols, liquids, and solids, as well as self-heating chemicals. (Common in salons: ethyl alcohol, acetone, aerosol hairsprays, styling mousse).
3. Exclamation Mark: Depicts a bold exclamation point. Identifies skin and eye irritants, skin sensitizers, acute toxicity (harmful), narcotic effects, and respiratory tract irritants. (Common in salons: artificial nail primers, permanent wave neutralizers, hair coloring creams).
4. Gas Cylinder: Depicts a pressurized gas tank. Identifies gases under pressure, liquefied gases, and dissolved gases. (Common in salons: propellant canisters in aerosol styling products).
5. Corrosion: Depicts liquid pouring from two glass test tubes, corroding a metal bar and a human hand. Identifies skin corrosion/burns, permanent eye damage, and corrosiveness to metals. (Common in salons: sodium hydroxide lye relaxers, concentrated ammonium thioglycolate, glycolic chemical peels, concentrated disinfectant solutions).
6. Exploding Bomb: Depicts an exploding spherical bomb. Identifies explosives, self-reactive substances, and organic peroxides.
7. Flame Over Circle (Oxidizers): Depicts an open flame rising above a circular letter "O". Identifies oxidizing chemicals that supply oxygen to intensify fires. (Common in salons: hydrogen peroxide developers, persulfate hair lightening powder boosters).
8. Environment (Non-Mandatory for OSHA): Depicts a dead tree and a dying fish. Identifies acute and chronic aquatic toxicity.
9. Skull and Crossbones: Depicts a human skull over crossed femur bones. Identifies acute toxicity (fatal or toxic substances that can cause death through ingestion, skin absorption, or inhalation).

The Mandatory 16-Section Safety Data Sheet (SDS)

Prior to GHS alignment, chemical manufacturers issued Material Safety Data Sheets (MSDSs) that varied wildly in length, organization, and terminology. Under the revised HCS, OSHA mandates that all manufacturers provide a standardized, 16-section Safety Data Sheet (SDS) formatted in a strict, sequential order:

Detailed Breakdown of SDS Sections 1–16

• Section 1: Identification: Identifies the chemical name, trade name, manufacturer or distributor contact details, and a 24-hour emergency phone number.
• Section 2: Hazard(s) Identification: Details the GHS classification, required signal word ("Danger" or "Warning"), hazard statements, precautionary statements, and required pictograms.
• Section 3: Composition / Information on Ingredients: Identifies chemical ingredients, common synonyms, Chemical Abstracts Service (CAS) registry numbers, and concentrations or percentage ranges.
• Section 4: First-Aid Measures: Crucial initial response instructions by exposure route: inhalation, skin contact, eye contact, and ingestion. Lists acute and delayed symptoms.
• Section 5: Fire-Fighting Measures: Lists suitable and unsuitable extinguishing media, specific chemical hazards resulting from fire, and specialized protective equipment for firefighters.
• Section 6: Accidental Release Measures: Detailed emergency procedures, spill response protocols, containment techniques, and necessary personal protective equipment (PPE).
• Section 7: Handling & Storage: Safe chemical handling procedures, incompatible chemical hazards, ventilation requirements, and specific temperature/storage limits.
• Section 8: Exposure Controls / Personal Protection: Outlines OSHA Permissible Exposure Limits (PELs), ACGIH Threshold Limit Values (TLVs), engineering ventilation controls, and required personal protective equipment (gloves, goggles, respirators).
• Section 9: Physical & Chemical Properties: Lists physical characteristics: appearance, odor, color, pH, boiling point, flash point, evaporation rate, vapor density, and water solubility.
• Section 10: Stability & Reactivity: Details chemical stability, potential for dangerous reactions, incompatible materials to avoid, and hazardous decomposition byproducts.
• Section 11: Toxicological Information: Describes routes of biological exposure (inhalation, ingestion, skin/eye contact), immediate and delayed health effects, chronic toxicity, and carcinogenicity listings.
• Sections 12–15 (Non-Mandatory under OSHA): Ecological Information (Section 12), Disposal Considerations (Section 13), Transport Information (Section 14), and Regulatory Information (Section 15). (Enforced by EPA and DOT).
• Section 16: Other Information: Date of SDS preparation, last revision date, and technical reference notes.

Salon SDS Compliance & Master Binder Protocols

To comply with OSHA regulations and state board rules, salon management and stylists must maintain strict chemical documentation:

1. Comprehensive Inventory: The salon must maintain an up-to-date SDS for every single hazardous chemical product present on the premises—including shampoos, permanent hair colors, developers, perms, relaxers, disinfectants, acetone, and acrylic powders.
2. Immediate Employee Accessibility: SDS records must be organized in a master binder located in an accessible common area (such as the chemical dispensary or breakroom) or accessible on an unrestricted computer terminal. SDSs cannot be locked inside an owner's private office, and employees cannot be required to ask permission or enter a password to view an SDS.
3. Employee Training: Employers must train employees about chemical hazards at initial assignment and whenever a new hazard is introduced. Minnesota adds that every salon must inform all licensees about chemical hazards and protective measures at least once every 12 months (Minn. R. 2105.0370, item B).

FDA and EPA: The Other Two Safety Agencies

The general theory outline lists three safety agencies. OSHA protects workers; the other two regulate the products you use.

Food and Drug Administration (FDA)

• Cosmetics law. The FDA regulates cosmetics under the Federal Food, Drug, and Cosmetic (FD&C) Act of 1938 and the Modernization of Cosmetics Regulation Act of 2022 (MoCRA). Most cosmetic ingredients need no FDA approval before sale, but color additives must be FDA-approved, with one exception: coal-tar hair dyes.
• Coal-tar hair dyes. Permanent, semi-permanent and temporary synthetic-organic ("coal-tar") hair dyes may be sold without approval only if they carry the required caution statement and directions for a preliminary skin (patch) test, which the FDA says to perform before every use. The FDA also states that eyebrow and eyelash dyeing are not permitted uses of coal-tar hair dyes.
• Progressive dyes. The FDA repealed approval of lead acetate in hair dyes (final rule effective January 6, 2022); bismuth citrate and henna remain approved color additives for hair.
• MoCRA duties for manufacturers. The "responsible person" must report serious adverse events to the FDA within 15 business days, register manufacturing facilities (renewed every two years) and list each product with its ingredients. MoCRA also gave the FDA mandatory recall authority.
• Devices. Autoclaves and other sterilizers are FDA-regulated devices; Minnesota requires sterilizers used in salons to be FDA registered and listed (Minn. R. 2105.0375, subp. 4a).
• Reporting. A licensee or client who experiences a reaction to a cosmetic can report it to the FDA after getting any needed medical care.

Environmental Protection Agency (EPA)

• Disinfectants are antimicrobial pesticides, so the EPA registers them and approves their label claims. The label shows an EPA registration number, the organisms the product kills, and the contact time.
• Using a registered product in a way that is inconsistent with its label violates federal law, which is why Minnesota's rule says to follow the manufacturer's dilution, contact time and disposal directions.
• Minnesota requires hospital-level, EPA-registered disinfectants that are bactericidal, virucidal and fungicidal (Minn. R. 2105.0010, subp. 4c; 2105.0375, subp. 4).

Personal Protective Equipment (PPE) in Salon Operations

Personal protective equipment acts as a physical barrier shielding practitioners from chemical splashes, caustic burns, and infectious materials:

1. Protective Gloves: Nitrile vs. Latex

• Nitrile Gloves (Recommended Industry Standard): Constructed from synthetic rubber copolymer. Nitrile gloves provide exceptional puncture resistance and superior chemical resistance against hair colors, developers, persulfate lighteners, chemical relaxers, and nail monomers. Most importantly, nitrile contains no natural rubber latex proteins, so it avoids latex allergy (although chemical additives in any glove can still irritate some wearers).
• Latex Gloves (High Risk): Natural rubber latex gloves contain plant proteins that frequently trigger Type I immediate allergic reactions (hives, respiratory constriction, systemic anaphylaxis) and Type IV delayed contact dermatitis in both practitioners and clients. Furthermore, latex degrades rapidly upon exposure to acetone and petroleum solvents.
• Vinyl Gloves: Often loose-fitting, prone to tearing, and provide inferior chemical barrier protection against harsh salon compounds.

2. Eye & Face Protection

Protective safety eyewear—specifically splash goggles or safety glasses with side shields—must be worn whenever decanting, mixing, or measuring concentrated disinfectants, hair lighteners, or chemical relaxers to prevent irreversible chemical corneal burns.

3. Protective Clothing & Footwear

Cosmetologists should wear chemical-resistant aprons or smocks to protect personal clothing and prevent skin contamination. Open-toed shoes, sandals, and canvas footwear are prohibited by safety standards; closed-toe leather or synthetic shoes protect feet from dropped shears and hot chemical spills.

Chemical Exposure Limits & Salon Ventilation Protocols

Cosmetology chemical services generate airborne particulates, aerosols, and volatile organic compound (VOC) vapors. Salons must implement adequate engineering controls:

General HVAC vs. Local Exhaust Source Capture

• General Salon HVAC: Recirculating heating and cooling systems dilute room air but do not adequately remove concentrated heavy chemical vapors generated at the station.
• Local Exhaust Source-Capture Systems: Vented manicuring tables with built-in downdraft suction and localized styling station exhaust hoods capture chemical vapors, monomer fumes, and file dusts directly at the point of generation before they reach the practitioner's breathing zone.

The OSHA Formaldehyde Standard (29 CFR 1910.1048)

Heat-activated Brazilian-style keratin hair smoothing treatments have historically posed severe occupational health risks. Many smoothing formulations contain methylene glycol, a liquid chemical that decomposes into airborne formaldehyde gas when heated with a 450°F flat iron:

• Formaldehyde is a potent sensitizer, respiratory toxin, and recognized human carcinogen.
• OSHA Formaldehyde Thresholds:
  • Action Level: 0.5 parts per million (ppm) calculated as an 8-hour Time-Weighted Average (TWA). Reaching this level triggers mandatory regular air monitoring and medical surveillance.
  • Permissible Exposure Limit (PEL): 0.75 ppm as an 8-hour TWA. The maximum legal allowable occupational limit.
  • Short-Term Exposure Limit (STEL): 2.0 ppm for any 15-minute sampling period.
