Chemical Inventory Reconciliation Audit Checklist [FREE PDF]

Chemical inventory reconciliation audits are required under EPA EPCRA Sections 311-313 for facilities that store or use hazardous chemicals above threshold planning quantities, and under OSHA 29 CFR 1910.1200 to maintain accurate Safety Data Sheet inventories. Facilities subject to OSHA PSM (29 CFR 1910.119) must additionally reconcile highly hazardous chemical quantities against process safety information at least annually. Accurate reconciliation prevents regulatory penalties, ensures emergenc

Master Chemical Inventory Records Review

Verify that the master chemical inventory list is current, complete, and accessible to required personnel.

  • Is a current master chemical inventory list maintained and dated within the last 90 days?
  • Does the inventory list include all required fields: chemical name, CAS number, quantity, and storage location?
  • Is the inventory cross-referenced with the current SDS library to confirm all chemicals have a corresponding Safety Data Sheet?
  • Are new chemicals added to the inventory within the required timeframe before or upon receipt?
  • Have chemicals that are no longer in use been removed or flagged as inactive in the inventory within the past audit cycle?

Physical Count and Quantity Verification

Reconcile physical quantities on hand against inventory records and identify discrepancies.

  • Has a complete physical count of all chemicals been conducted and documented this audit period?
  • Is the physical quantity variance between records and actual count within the accepted tolerance threshold (e.g., ±5%)?
  • What is the total number of discrepancies identified between physical count and inventory records?
  • Are container quantities measured and recorded in consistent units of measure (e.g., lbs, gallons) as required for regulatory reporting?
  • Are chemicals stored in satellite accumulation areas or secondary locations included in the physical count?
  • Please document any significant discrepancies or observations noted during physical count.

Threshold Planning Quantity (TPQ) and Reporting Thresholds

Confirm that extremely hazardous substances and PSM chemicals are identified and tracked against regulatory thresholds.

  • Have all Extremely Hazardous Substances (EHS) been identified on the inventory and compared against EPCRA Section 302 TPQ thresholds?
  • Are PSM-covered highly hazardous chemicals tracked and verified to be below or above their 29 CFR 1910.119 Appendix A thresholds?
  • Are EPCRA Section 313 Toxic Release Inventory (TRI) chemicals tracked for annual release reporting thresholds?
  • Does the facility have a documented threshold tracking system with alerts when quantities approach 80% of regulatory limits?
  • Has the SPCC Plan been reviewed to confirm that oil and petroleum product inventories are consistent with volumes stated in the plan?

SDS Library and GHS Labeling Verification

Ensure all chemicals in inventory have compliant GHS labels and up-to-date Safety Data Sheets.

  • Are all chemicals in the inventory associated with a GHS-compliant SDS (16-section format) from the manufacturer?
  • Are SDSs verified to be less than 5 years old, or have older SDSs been confirmed current with the manufacturer?
  • Are all in-plant containers and secondary containers labeled with GHS-compliant labels including pictograms, signal word, hazard statements, and precautionary statements?
  • Are chemicals used in DOT-regulated transport labeled and placarded according to 49 CFR 172 requirements?
  • Is a sample spot-check of 10% of inventory chemicals showing matching labels, SDS, and inventory record (chemical name, CAS, hazard class) completed?

Chemical Storage Segregation and Compatibility

Confirm stored chemicals are properly segregated by hazard class and chemical incompatibility.

  • Are incompatible chemicals identified on the inventory and confirmed to be stored in segregated areas with physical barriers?
  • Are flammable liquids inventoried quantities consistent with NFPA 30 maximum allowable quantities for the storage area classification?
  • Are corrosive chemicals stored on low shelves or in dedicated corrosive cabinets to prevent fall and spill risk?
  • Are oxidizing agents stored separately from organic materials, flammables, and combustibles with a minimum 3-foot separation or physical barrier?
  • Does the inventory map (chemical location diagram) accurately reflect the current physical location of all chemicals?

Chemical Disposal, Transfer, and Use Tracking

Reconcile chemical usage, transfers, and disposal events against inventory reductions.

  • Are all chemical disposals and waste transfers documented with date, quantity, waste manifest number, and licensed disposal company?
  • Are inter-departmental or inter-building chemical transfers logged with date, quantity, receiving department, and authorization?
  • Are chemical usage/consumption logs maintained for batch processes and do they reconcile with inventory reductions within the audit period?
  • Have any unexplained inventory losses or gains been investigated, documented, and reported to the EHS Manager?
  • Are TRI chemical release and transfer calculations initiated using inventory reconciliation data for annual Form R reporting?

Emergency Planning and Notification Record Verification

Confirm that emergency planning documents reflect current inventory data and required notifications are current.

  • Has the LEPC (Local Emergency Planning Committee) been notified of any new EHS chemicals or significant quantity changes since the last audit?
  • Is the facility's annual Tier II report (EPCRA Section 312) consistent with the reconciled inventory data from this audit period?
  • Does the Emergency Response Plan (ERP) chemical list match the current reconciled inventory, including hazard classes and locations?
  • Are SPCC Plan inventory volumes updated to reflect any changes in maximum storage capacity identified during this reconciliation?
  • Have corrective actions from the previous inventory reconciliation audit been verified as completed and closed out?
  • Please summarize overall audit findings, corrective actions required, and recommended follow-up timeline.
