Salon chemical safety is both a regulatory requirement and a genuine occupational health imperative. The beauty industry uses a wide range of chemical products — hair color oxidizers, keratin smoothing agents, chemical relaxers, acetone-based removers, acrylates in nail products, disinfectants, and aerosol sprays — many of which carry real hazards if handled improperly. OSHA's Hazard Communication Standard (HazCom) requires employers to maintain Safety Data Sheets, provide employee training, and implement chemical management systems. This guide covers everything you need to know to build a compliant and genuinely safe chemical management program in your salon.
The Occupational Safety and Health Administration's Hazard Communication Standard (29 CFR 1910.1200), commonly called HazCom or the "Right to Know" standard, establishes the minimum requirements for managing hazardous chemicals in the workplace. Salons that use hazardous chemicals — and virtually all salons do — are subject to these requirements.
Safety Data Sheets (SDS). Formerly called Material Safety Data Sheets (MSDS), Safety Data Sheets provide comprehensive information about each hazardous chemical, including its chemical composition, physical and health hazards, exposure limits, proper storage and handling requirements, emergency response procedures, and first aid information. Under the current GHS-aligned HazCom standard, SDSs follow a 16-section format.
SDS availability requirements. OSHA requires that SDSs be readily accessible to employees at all times during their work shift. "Readily accessible" means that an employee could access the SDS in an emergency without significant delay. SDSs stored in a locked office cabinet fail this standard. A binder stored in the color room, a digital tablet with SDS access software, or a workplace SDS management platform all satisfy the requirement, provided employees know where to find them and can access them quickly.
Chemical inventory. Employers must maintain a list of all hazardous chemicals present in the workplace. For a salon, this typically includes: all hair color products and developers, chemical straightening and waving solutions, bleach powders and lightening agents, acetone and similar solvents, disinfectants and sanitizers, nail products (primers, acrylics, gels), aerosol products, and any cleaning chemicals. Your chemical inventory should be reviewed and updated whenever you add or discontinue products.
Labeling requirements. All containers of hazardous chemicals must be properly labeled with the product name, the supplier's name and address, and appropriate hazard warnings. This applies to primary containers (original manufacturer containers) and to secondary containers (any container into which you transfer a chemical, including applicator bottles and mixing bowls). Never transfer a chemical into an unlabeled container.
Employee training. OSHA requires that employees receive training on the Hazard Communication Standard and on the specific hazardous chemicals they work with before they begin using those chemicals and whenever a new hazardous chemical is introduced. Training must cover: how to read and use SDSs, how to interpret GHS hazard labels, the physical and health hazards of the chemicals used in the salon, protective measures (including PPE requirements), and emergency procedures.
A functional SDS management system is the backbone of chemical safety compliance. Here is how to build one that works in a practical salon environment.
Gather SDSs for every chemical product in your salon. Contact your product distributors or manufacturers for SDSs for every product you use. Most manufacturers make current SDSs available on their websites. Be aware that SDSs are product-specific — a SDS for a specific hair color brand is not the same document as one for a different brand, even if the products seem similar.
Organize your SDS binder logically. Group SDSs by category (hair color products, chemical straighteners, disinfectants, nail products, cleaning products, etc.) and maintain an index so that any employee can locate the SDS for a specific product quickly. If your salon has multiple workrooms (color room, nail room, reception), consider keeping category-specific SDS collections in each relevant area.
Transition to digital SDS management. Several software platforms — including MSDSOnline, Velocity EHS, and similar services — provide digital SDS management with automatic updates when manufacturers revise their SDSs, searchable databases, and access from mobile devices. For larger salons or those with extensive chemical inventories, digital management significantly reduces the administrative burden of keeping SDS records current.
Update your SDS binder when products change. Many salons fail to update their SDS files when they switch to new product lines or add new products. Establish a procedure: whenever you receive a new product, obtain and file the SDS before the product is used in the salon.
Keep SDSs current. SDSs are revised when manufacturers update formulations or hazard classifications. As a best practice, verify that your SDSs are current (within the past five years) by checking the manufacturer's website annually.

Proper chemical storage and handling practices protect your staff, your clients, and your physical premises from the hazards posed by the chemicals you use.
Separation of incompatible chemicals. Some chemical categories can react dangerously when they come into contact with each other or with moisture, heat, or air. Oxidizing agents (such as hydrogen peroxide developers) should be stored separately from flammable or organic materials. Acids and alkalis should be stored separately. Review the SDS for each product category and follow the storage instructions provided.
Flammability hazards. Many aerosols and solvent-based products used in salons (hairsprays, nail solvents, acetone-based removers) are flammable. These products should be stored away from heat sources, electrical panels, and open flames. Ensure adequate ventilation in storage areas. Maintain appropriate fire extinguisher coverage.
Container integrity. Check chemical containers regularly for signs of damage, leaking, or degradation. Store containers in upright positions unless otherwise specified. Do not leave applicator bottles containing mixed chemicals (such as mixed color and developer) for extended periods — many oxidation-based reactions continue after mixing, generating pressure that can cause container failure.
Temperature requirements. Many chemical products have temperature storage requirements — some products degrade at high temperatures, and some (like hydrogen peroxide developers) decompose more rapidly when stored warm, reducing their effectiveness and potentially creating off-gassing. Store products in accordance with manufacturer specifications.
Dispensing practices. When dispensing chemicals — particularly when pouring from large containers into smaller applicator containers — follow the SDS guidance for appropriate PPE. Chemical splashes during dispensing are a common source of eye and skin exposure injuries. Use appropriate funnels, dispensing pumps, or other equipment to minimize splash risk.
Waste chemical handling. Never pour excess mixed chemicals (color and developer mixtures, for example) down the drain unless you have confirmed this is appropriate for your wastewater system. Some jurisdictions have specific requirements for the disposal of salon chemicals. Refer to the SDS waste disposal section and your local wastewater authority for guidance.
Running a successful salon means more than just great services — it requires maintaining the highest standards of cleanliness and safety. Your clients trust you with their health, and proper hygiene management protects both your customers and your business reputation. A single hygiene incident can undo years of hard work building your brand.

Choosing and using appropriate PPE correctly is a critical safety practice.
Gloves. Gloves are the most important PPE for chemical work in salons. Not all glove materials are appropriate for all chemicals. Nitrile gloves provide good protection against most hair color chemicals, oxidizers, and disinfectants. Latex gloves should be avoided due to the high prevalence of latex allergy among salon workers and clients. Consult the SDS for specific glove material recommendations. Change gloves between clients and whenever gloves are visibly contaminated or damaged. Wearing gloves correctly — without holes or tears, snug to the wrist — is as important as the material selection.
Eye protection. Chemical splash to the eyes is a medical emergency. During dispensing, mixing, and application of chemicals that could splash, appropriate eye protection — safety glasses or splash goggles — should be worn. The standard prescription eyeglasses do not provide adequate protection against chemical splashes. An eyewash station (or at minimum an emergency eyewash bottle) should be available in your chemical work area.
Skin protection and barrier creams. For stylists performing high volumes of wet work, barrier cream applications before beginning chemical services and during breaks can significantly reduce the risk of occupational contact dermatitis. Barrier creams do not replace gloves — they are a supplementary protection.
Respiratory protection. For services involving high-volatility chemicals (certain keratin treatments, strong relaxers, nail products in enclosed spaces), respiratory protection may be appropriate. The specific type of respirator required depends on the chemicals involved and the level of exposure — this should be determined based on the SDS and potentially a professional exposure assessment. General-purpose dust masks are not effective for chemical vapors.
Adequate ventilation is the single most important engineering control for reducing chemical exposure in salon environments. Many older salon buildings were not designed with chemical service ventilation in mind, and improving ventilation can require investment but typically delivers significant health benefits.
General dilution ventilation. At minimum, a salon should have adequate general ventilation — meaning sufficient air exchange to dilute and remove airborne contaminants generated during services. Modern building codes typically specify minimum ventilation rates for commercial spaces; however, the chemical load of salon services may exceed what the general HVAC system was designed to handle.
Local exhaust ventilation. For high-exposure services — particularly nail services, chemical relaxers, and certain keratin treatments — local exhaust ventilation (a ventilation system that captures contaminants at or near the point of generation before they disperse into the room air) provides significantly better protection than general dilution alone. This may include ventilated nail tables with built-in exhaust systems or portable capture ventilation units.
HEPA filtration. HEPA filtration units can supplement general ventilation by removing particulates from room air. They are valuable for reducing allergen and particulate load but do not remove gaseous chemical vapors — for vapor control, activated carbon filtration in addition to HEPA is required.
The OSHA Chemical Hazards resources for cosmetology provide specific ventilation guidance for salon environments, including quantitative exposure information for common salon chemicals.
Yes. Under OSHA's Hazard Communication Standard, employers must maintain an SDS for every hazardous chemical used in the workplace and make those SDS readily accessible to employees during their work shifts. Virtually all hair color products, chemical treatment products, disinfectants, and cleaning chemicals used in salons qualify as hazardous chemicals. Consumer-use products (products manufactured for consumer rather than professional use) are technically exempt from HazCom requirements when used as directed on the label, but professional-grade salon products are generally not consumer products and are subject to the standard. If you are uncertain whether a specific product is subject to HazCom requirements, check the SDS — if the manufacturer provides one, the product is covered.
OSHA's Hazard Communication Standard does not specify a retention period for SDS. However, OSHA's general recordkeeping rules require that exposure records and related medical records be retained for 30 years. Since SDS documents serve as exposure records — they document the hazardous chemicals employees have been exposed to — many compliance professionals recommend retaining SDSs for the full 30-year period for chemicals that have been used in the workplace. For ongoing products that are still in use, maintain current SDS at all times. For discontinued products, retain the most recent SDS for the period the product was in use.
In OSHA and state-level salon regulatory inspections, the most commonly cited chemical safety violations include: failure to maintain accessible SDS for all hazardous chemicals (SDS stored in locked or inaccessible locations), failure to provide employee training on hazardous chemicals before they begin using those chemicals, use of secondary containers (applicator bottles, mixing bowls) without proper labels, and failure to maintain a complete chemical inventory. These are also among the easiest violations to correct — a systematic SDS review and update, supplemented by documented employee training, addresses the majority of common compliance gaps. Using a compliance management tool like MmowW Shampoo's hygiene platform to organize and track your chemical safety documentation makes ongoing compliance significantly more manageable.
Chemical safety compliance is not a one-time project — it requires ongoing maintenance as products change, staff turn over, and regulations update. Build systems that make compliance the default rather than a periodic scramble: digital SDS management, documented training records, regular inventory reviews, and scheduled safety audits.
MmowW Shampoo's compliance platform is designed to support exactly this kind of ongoing, systematic safety management for salon professionals.
