Proper chemical storage is a foundational element of salon safety that protects staff, clients, and the business itself. Salons typically maintain inventories of dozens of chemical products, from hair colorants and oxidizers to disinfectants, cleaning agents, and styling products. Each category of product has specific storage requirements based on its chemical properties, and failing to meet these requirements creates risks ranging from product degradation to chemical reactions, fires, and toxic exposures. This guide covers the essential storage requirements for salon chemicals: selecting appropriate storage locations and containers, organizing products to prevent dangerous interactions, maintaining proper labeling, controlling environmental conditions, and documenting your storage practices for regulatory compliance.
Chemical storage problems in salons are dangerous precisely because they develop gradually and remain invisible until something goes wrong. Products stored incorrectly may not cause an immediate incident but can degrade over time, creating concentrated or altered formulations that behave unpredictably when used. Incompatible chemicals stored in proximity can react if containers leak or spill. Products stored near heat sources can build pressure in sealed containers, and aerosol cans stored in warm areas present explosion risks.
The most common chemical storage violations found during salon inspections include products stored in areas without adequate ventilation, chemicals stored above eye level where spills during retrieval can cause facial or eye contact, incompatible products stored adjacent to each other without separation, products transferred to unlabeled secondary containers, expired products remaining in active inventory, chemicals stored near food or beverages, flammable products stored near heat sources or ignition points, and storage areas accessible to unauthorized persons including clients.
These violations persist because chemical storage is often an afterthought in salon design. Storage space is allocated based on convenience and available square footage rather than safety requirements. Products are placed wherever they fit rather than where they belong. As product inventories grow, storage areas become crowded and disorganized, making proper separation increasingly difficult to maintain.
The consequences of improper storage extend beyond regulatory citations. Chemical degradation from improper temperature or light exposure wastes product and creates unpredictable service results. Chemical reactions from improper separation can produce toxic gases, fires, or corrosive mixtures. Spills from unstable shelving or overcrowded storage create immediate exposure and cleanup hazards. And the legal liability from a chemical incident traced to improper storage can be substantial.
Chemical storage regulations for salons draw from general workplace safety standards and specific cosmetology board requirements. While details vary by jurisdiction, the core requirements are consistent.
Location: Chemical storage areas must be separate from client service areas, food preparation or consumption areas, and personal belongings storage. The storage area must be ventilated, either by natural airflow through windows or vents or by mechanical ventilation. Storage areas must not be exposed to direct sunlight, excessive heat, or sources of ignition.
Shelving and Arrangement: Chemicals must be stored on stable, level shelving that is appropriate for the weight of the products. Heavy containers and liquids should be stored at waist height or below to minimize the risk and severity of spills. Products should never be stored directly on the floor where they may be kicked, stepped on, or exposed to water from floor cleaning. Shelving must be secured to prevent tipping.
Labeling: All products must be stored in their original manufacturer containers with original labels intact and legible. If products must be transferred to secondary containers for dispensing, each secondary container must be clearly labeled with the product name, active ingredients, hazard warnings, and the date of transfer. Unlabeled containers are a common citation during inspections.
Separation: Incompatible chemicals must be stored separately. The specific incompatibilities are identified on each product's Safety Data Sheet. In general, oxidizers (including hydrogen peroxide developers) must be separated from flammable materials, acids must be separated from bases, and concentrated chemicals must be separated from ready-to-use products to prevent confusion.
Access Control: Chemical storage areas should be accessible only to trained staff. Clients, particularly children, must not have access to chemical storage areas. Storage rooms or cabinets should be lockable when the salon is closed.
Inventory Management: While not universally regulated, good practice and some jurisdictions require maintaining an inventory of chemicals on-site, including quantities. Expired products must be removed from active storage and disposed of properly.

Before organizing storage, know exactly what you have. Inventory every chemical product in your salon, including products currently on shelves, in workstation drawers, in back rooms, and in any overflow storage. Note the product name, manufacturer, quantity, purchase date or expiration date, and current storage location. Identify and set aside any expired products for proper disposal.
Step 2: Review SDS for Storage Requirements
For each product in your inventory, review Section 7 (Handling and Storage) of its Safety Data Sheet. Note specific storage requirements including temperature range, ventilation needs, incompatibilities, and any special conditions. Group products by their storage requirements, as this will guide your physical organization.
Step 3: Designate and Prepare Storage Areas
Select or redesign your chemical storage area to meet the requirements identified in your SDS review. Ensure adequate ventilation. Install stable, level shelving rated for the weight it will carry. Secure shelving to walls to prevent tipping. Ensure the area has adequate lighting so labels can be read easily. If you cannot dedicate a separate room to chemical storage, use a well-ventilated cabinet or closet with a door that can be closed to separate chemicals from the service area.
Step 4: Organize by Compatibility and Frequency of Use
Arrange products on shelves based on chemical compatibility first and frequency of use second. Place oxidizers on separate shelves from flammable products. Store acids away from bases. Place frequently used products at the most accessible heights (waist to shoulder level) and less frequently used products higher or lower. Store the heaviest containers at the lowest level. Leave space between product groups for spill containment and for new products to be added without disrupting the organization.
Step 5: Implement Labeling Standards
Verify that every product in storage has its original manufacturer label intact and legible. For any secondary containers used for dispensing at workstations, create clear labels that include the product name, key hazardous ingredients, basic hazard warnings, and the date of transfer. Replace any labels that are faded, torn, or stained. Consider adding shelf labels that indicate which products belong in each location to help staff return products to the correct spot.
Step 6: Establish Daily Storage Routines
Integrate storage management into daily operations. At the end of each day, verify that all products have been returned to their designated storage locations and that container lids are secure. Check for spills or leaks. Verify that the storage area door is closed. On a monthly basis, check inventory levels, identify expired products for disposal, verify that all labels are legible, and ensure that the storage area remains organized and clean.
Q: Can salon chemicals be stored in a bathroom or break room?
A: No. Salon chemicals should not be stored in restrooms, kitchens, break rooms, or any area used for food preparation or consumption. The risk of contamination in both directions is the concern: food or personal items can be contaminated by chemical proximity, and restroom humidity can degrade chemical products. Most regulations explicitly prohibit the co-location of chemicals with food, beverages, or personal care items. Designate a separate, ventilated area exclusively for chemical storage. If space constraints make this challenging, even a dedicated, ventilated cabinet within the salon work area is preferable to storing chemicals in non-suitable spaces.
Q: How should aerosol products be stored?
A: Aerosol products, including hairsprays, dry shampoos, and some disinfectant sprays, require specific storage precautions because they contain pressurized contents and often flammable propellants. Store aerosols at room temperature, away from heat sources, direct sunlight, and any open flame. Do not store aerosols above 50 degrees Celsius (120 degrees Fahrenheit), as excessive heat can cause containers to rupture or explode. Keep aerosol cans upright to prevent valve leakage. Do not puncture or incinerate aerosol containers even when empty. Most regulations classify aerosol products as flammable and require their storage to comply with flammable materials standards, including separation from ignition sources and oxidizers.
Q: What should I do with expired salon chemical products?
A: Expired chemical products should be removed from active storage and disposed of according to local regulations. Do not pour expired chemicals down the drain unless the product's SDS specifically confirms that drain disposal is acceptable. Many expired salon chemicals, particularly color products, developers, and chemical treatments, may need to be disposed of as hazardous waste through a licensed waste disposal service. Contact your local environmental agency for guidance on proper disposal methods. Some manufacturers and distributors offer take-back programs for expired products. As a prevention measure, implement a first-in, first-out inventory rotation system and purchase quantities that match your usage rate to minimize product expiration.
