Hazardous Chemical Storage Audit Checklist [FREE PDF]

Hazardous chemical storage audits in laboratory settings are governed by OSHA 29 CFR 1910.1450 (Laboratory Standard), EPA 40 CFR Part 262 (Generator Standards for Hazardous Waste), and GLP regulations under 21 CFR 58 Subpart B. Improper segregation, labeling failures, and inadequate secondary containment are among the most frequently cited deficiencies during CAP accreditation and EPA inspections. This audit systematically evaluates chemical inventory management, storage compatibility, container

  • Industry: Research & Development

  • Compliance: OSHA 29 CFR 1910.1450 - Occupational Exposure to Hazardous Chemicals in Laboratories, OSHA 29 CFR 1910.1200 - Hazard Communication Standard (GHS), EPA 40 CFR Part 262 - Standards Applicable to Generators of Hazardous Waste, GLP 21 CFR 58 Subpart B - Facilities, CAP Accreditation Standards - CHM.13600 Chemical Storage Safety

Chemical Inventory Management

Confirm that a current, accurate chemical inventory is maintained and accessible, supporting regulatory reporting and hazard communication.

  • Is a complete and current chemical inventory maintained for all hazardous chemicals in the laboratory?
  • Does the inventory include chemical name, CAS number, quantity, location, and hazard classification?
  • Has the chemical inventory been updated within the past 90 days?
  • Are Safety Data Sheets (SDS) available in GHS format for every chemical on the inventory?
  • Are chemicals with quantities above OSHA Process Safety Management (PSM) thresholds identified and reported?

Chemical Container Labeling

Verify that all chemical containers are properly labeled in accordance with GHS Hazard Communication standards.

  • Are all primary chemical containers labeled with the product identifier, supplier information, and GHS signal word?
  • Are secondary (transferred) containers labeled with chemical identity and primary hazards?
  • Are all container labels legible, intact, and free from chemical damage or obscuring tape?
  • Are expiration or preparation dates visible on all in-house prepared solutions and reagents?
  • Are GHS pictograms correctly applied and matched to the chemical's hazard classification?
  • Are empty chemical containers decontaminated and labeled as 'Empty' before disposal or reuse?

Chemical Segregation & Compatibility

Assess the segregation of incompatible chemical classes to prevent dangerous reactions from accidental mixing.

  • Are flammable liquids stored separately from oxidizers, corrosives, and reactive materials?
  • Are acids and bases stored in separate, compatible secondary containment units?
  • Are peroxide-forming chemicals (e.g., THF, diethyl ether) dated, tracked, and tested for peroxide formation?
  • Are toxic and highly toxic chemicals (acutely toxic, carcinogens) stored in dedicated, secured locations?
  • Are incompatible chemical groups identified with segregation maps or color-coded storage systems?

Secondary Containment & Spill Prevention

Evaluate secondary containment structures and spill prevention measures for all hazardous chemical storage areas.

  • Are secondary containment trays or berms in place under all liquid chemical storage areas?
  • Is secondary containment capacity at least 10% of the total stored volume or the volume of the largest container?
  • Are secondary containment units free from accumulated liquid, chemical residue, or debris?
  • Are chemical storage areas located away from floor drains, sinks, and HVAC air intakes?
  • Are chemical spill kits stocked with appropriate neutralizers and absorbents for the chemicals stored in this area?

Container Integrity & Storage Conditions

Inspect chemical containers for physical integrity and verify that storage conditions meet manufacturer and regulatory requirements.

  • Are all chemical containers free from cracks, bulging, corrosion, or leaking seals?
  • Are container caps, stoppers, and lids fully tightened and in good condition?
  • Are temperature-sensitive chemicals stored in appropriately rated refrigerators or freezers with temperature monitoring?
  • Are laboratory refrigerators used for chemical storage spark-free and labeled 'No Food or Beverages'?
  • Are chemical containers stored at or below maximum allowable bench-top quantities per laboratory policy?
  • Are heavy chemical containers stored at or below waist height to prevent dropping injuries?

Hazardous Waste Storage & Compliance

Audit hazardous waste accumulation areas for compliance with EPA generator standards and proper waste container management.

  • Are hazardous waste containers clearly labeled with 'Hazardous Waste', the waste contents, and the accumulation start date?
  • Are hazardous waste containers kept closed except when actively adding waste?
  • Are accumulation time limits being met (90, 180, or 270 days depending on generator status)?
  • Are waste containers compatible with the waste contents and free from deterioration?
  • Is the hazardous waste accumulation area equipped with secondary containment and spill materials?

Ventilation & Personal Protective Equipment

Assess the adequacy of laboratory ventilation systems and the availability and use of appropriate personal protective equipment for chemical storage areas.

  • Are chemical storage areas equipped with adequate ventilation to prevent vapor accumulation above OSHA PELs?
  • Are fume hood sash heights within the safe operating range and sash marked with the maximum operating height?
  • Have fume hoods been certified and airflow tested within the past 12 months?
  • Is appropriate PPE (gloves, goggles, lab coat) available and accessible in all chemical storage areas?
  • Are chemical-resistant gloves available in appropriate materials for the chemicals stored in this area?
  • Are splash goggles (not safety glasses) required and used when handling corrosive or reactive chemicals?

Training Records & Compliance Documentation

Verify that chemical storage compliance training is current for all laboratory personnel and that required records are properly maintained.

  • Have all laboratory personnel completed annual Hazard Communication (HazCom) training?
  • Have personnel handling hazardous waste completed EPA-required hazardous waste training?
  • Are training records for all laboratory personnel retained for the minimum required period of 3 years?
  • Is there a documented corrective action plan for deficiencies identified in previous chemical storage audits?
  • Are chemical storage audit records maintained and accessible for regulatory review upon request?
