Diesel Exhaust Fluid (DEF) Display Tank Storage Audit

Inspection template for verifying DEF jugs and bulk dispensers are stored away from heat sources, properly labeled, and maintained in a safe, compliant condition in auto parts or retail environments.

Inspection Scope and Location

• DEF storage area identified and included in scope
  Confirm the inspection covers all DEF jugs, display tanks, and bulk dispensers in the designated sales, storage, or service area.
• Location and date of inspection recorded
  Document the exact store, department, aisle, bay, or other location inspected, along with the inspection date/time if needed.
• Inspector observed all accessible DEF containers and dispenser points
  Verify the inspector visually checked the full display, including top stock, end caps, bulk dispenser connections, and any secondary storage nearby.
• Any restricted or back-room DEF storage identified
  Note whether additional DEF inventory is stored outside the display area and whether it was included in the audit.

Heat Exposure and Storage Conditions

• DEF jugs stored away from direct heat sources
  Check that jugs are not placed next to heaters, furnaces, hot equipment, sun-exposed windows, steam lines, or other elevated-temperature sources.
• Bulk DEF dispenser located away from heat-producing equipment
  Verify the dispenser is not positioned near HVAC discharge, engine exhaust, radiant heaters, or other heat-producing equipment that could affect product quality or container integrity.
• No visible signs of heat damage, swelling, leakage, or deformation
  Inspect containers and dispenser components for warping, bulging, discoloration, softened plastic, cracked fittings, or evidence of leakage.
• Ambient storage temperature appears suitable for DEF display
  Record any measured or observed temperature concerns if a thermometer or building control indication is available. Note if the area is subject to prolonged direct sunlight or extreme heat.

Container Condition and Product Identification

• DEF jugs are sealed and undamaged
  Confirm caps, seals, and closures are intact and containers show no cracks, punctures, or evidence of tampering.
• Product labels are legible and identify DEF correctly
  Verify labels are readable and clearly identify the product as diesel exhaust fluid, including any required handling or storage warnings.
• Containers are stored upright and stable
  Check that jugs and any smaller containers are upright, not leaning, and not at risk of falling or spilling.
• Bulk dispenser hoses, nozzles, and fittings are intact
  Inspect the dispenser for cracked hoses, damaged nozzles, missing caps, loose fittings, or other defects that could cause contamination or leakage.

Housekeeping, Segregation, and Spill Readiness

• DEF storage area is clean and free of spills
  Look for residue, puddles, sticky buildup, or dried product around the display, floor, shelves, and dispenser base.
• DEF is segregated from incompatible materials and contamination sources
  Verify DEF is not stored with fuels, oils, solvents, chemicals, or dirty tools that could contaminate the product.
• Spill response materials are available and accessible
  Confirm absorbent materials or spill cleanup supplies are available near the storage area and not blocked.
• Aisles and access to DEF storage remain unobstructed
  Ensure the display and dispenser can be accessed safely for stocking, customer use, and emergency response.

Records, Training, and Corrective Actions

• Deficiencies documented with location and corrective action
  Record each deficiency or non-conformance, including what was observed, where it was found, and the corrective action taken or needed.
• Responsible person assigned for follow-up
  Identify the manager, supervisor, or competent person responsible for correcting any issues.
• Staff understand DEF storage away from heat requirement
  Confirm employees responsible for merchandising or stocking can explain the basic storage expectation and escalation process for heat-related concerns.
• Reference to store SOP or manufacturer guidance available
  Verify there is a local procedure, planogram note, or manufacturer guidance available for DEF storage and display practices.
