Car Wash Chemical Mixing & Storage Audit Checklist [FREE PDF]

Car wash facilities store and handle a variety of chemicals including surfactants, degreasers, tire dressings, and protectants that may be classified as flammable liquids, corrosives, or hazardous substances under OSHA 29 CFR 1910.1200 Hazard Communication Standard and NFPA 30 Flammable and Combustible Liquids Code. Improper storage, mixing, or labeling of these chemicals creates fire hazards, chemical exposure risks for employees, and potential environmental contamination through spills or impr

Chemical Inventory & Labeling

Verify that all chemical products are properly inventoried, labeled, and matched to current Safety Data Sheets.

Are all chemical containers properly labeled with product name, hazard warnings, and manufacturer information?
Is a current Safety Data Sheet (SDS) available on-site for every chemical product in use or storage?
Is the SDS binder or electronic system organized, current (within 3 years), and accessible to all employees?
Are all bulk chemical totes or transfer containers labeled with the correct product name and hazard classification?
Is the chemical inventory log current and does it reflect all products currently on site?

Flammable & Combustible Liquid Storage

Assess storage conditions for flammable and combustible liquids including degreasers and solvent-based protectants.

Are flammable liquids stored in approved flammable storage cabinets meeting NFPA 30 and OSHA specifications?
Is the total quantity of flammable liquids stored outside of approved cabinets within OSHA 1910.106 limits?
Are flammable liquid storage areas free of ignition sources including open flames, sparks, and non-explosion-proof electrical equipment?
Are flammable liquid containers kept tightly sealed when not in immediate use?
Is there adequate ventilation in chemical storage areas to prevent flammable vapor accumulation above 25% of LEL?

Chemical Compatibility & Segregation

Verify incompatible chemicals are properly segregated to prevent dangerous reactions.

Are acids and alkaline (caustic) chemicals stored in separate, physically segregated areas?
Are oxidizing chemicals stored away from flammable or combustible liquids by at least 3 feet or a fire-rated barrier?
Is a chemical compatibility chart posted in the storage area showing which products must not be mixed or stored together?
Are corrosive chemicals (pH below 4 or above 10) stored in secondary containment preventing spill contact with other products?

Chemical Mixing & Dispensing Safety

Evaluate chemical mixing stations, dilution systems, and dispensing equipment for safe operation.

Are automated chemical dilution systems calibrated to manufacturer-specified dilution ratios and tested within the last 30 days?
Are chemical injection metering tips or nozzles free of blockage, wear, or unauthorized modification?
Is a chemical-resistant drip tray or secondary containment present at all chemical dispensing points?
Are chemical transfer pumps, hoses, and fittings in good condition and free of leaks or chemical degradation?
Is the chemical mixing/dispensing area free of food, drink, and personal items that could become contaminated?
Are measuring devices (graduated cylinders, dispensing guns) available and used for accurate chemical measurement?

PPE & Emergency Response Equipment

Confirm availability and condition of personal protective equipment and emergency response resources.

Is appropriate PPE (chemical-resistant gloves, eye protection, apron) available at all chemical handling areas?
Is an emergency eyewash station accessible within 10 seconds (approximately 55 feet) of all chemical handling areas?
Has the eyewash station been flushed and tested within the last 7 days and is it free of obstruction?
Is a chemical spill kit stocked with appropriate absorbents and neutralizers readily available in the storage area?
Is a fire extinguisher (ABC or CO2 rated) located within 25 feet of the chemical storage area and inspected within the last 12 months?

Spill Prevention & Chemical Waste Disposal

Review spill prevention measures, waste chemical disposal procedures, and environmental safeguards.

Is a Spill Prevention, Control, and Countermeasure (SPCC) plan available if oil storage exceeds 1,320 gallons aggregate aboveground?
Are floor drains in the chemical storage area connected to the sanitary sewer (not stormwater) or plugged?
Are expired or waste chemicals stored in properly labeled waste containers awaiting disposal through a licensed hauler?
Has a spill occurred since the last audit, and if so, was it properly reported and documented?
Are empty chemical containers disposed of or returned per SDS instructions and not reused for other products?

Employee Training & Compliance Documentation

Verify that staff chemical handling training is current and all compliance documentation is maintained.

Have all employees who handle chemicals received HazCom/GHS training within the last 12 months?
Are chemical handling training records signed and dated by each employee and retained on file?
Are emergency contact numbers (poison control, fire, chemical supplier emergency line) posted in the chemical storage area?
Has the chemical storage area been audited by a manager or supervisor within the last 30 days?
Please note any chemical storage deficiencies found during this audit and required corrective actions with target dates:
