Chemical Storage Compatibility Audit Checklist [FREE PDF]

Chemical storage compatibility audits are essential to prevent dangerous reactions between incompatible substances, as mandated by OSHA 29 CFR 1910.1200 and NFPA 30. Improper segregation of flammable, oxidizing, corrosive, and reactive chemicals is a leading cause of facility fires, explosions, and toxic releases. This checklist guides Chemical Safety Officers through a systematic evaluation of storage areas, container integrity, segregation practices, and secondary containment systems.

Industry: Chemical Manufacturing
Frequency: Monthly
Estimated Time: 45-60 minutes
Role: Chemical Safety Officer
Total Items: 36
Compliance: OSHA 29 CFR 1910.1200 - Hazard Communication GHS, OSHA 29 CFR 1910.119 - Process Safety Management, NFPA 30 - Flammable and Combustible Liquids Code, EPA 40 CFR 112 - SPCC Oil Pollution Prevention, EPA EPCRA Section 311-312 - Chemical Inventory Reporting

Chemical Inventory Review

Verify that the chemical inventory is current, accurate, and accessible to all authorized personnel.

Is a current chemical inventory list maintained and accessible in the storage area?
Are all chemicals in storage included in the current SDS library?
Are quantities of stored chemicals within permitted or reported thresholds?
Are new chemicals added to inventory before being placed into storage?
Is the inventory record dated within the last 30 days?

Chemical Segregation & Compatibility

Assess whether incompatible chemicals are properly identified, segregated, and stored to prevent hazardous reactions.

Are flammable liquids stored separately from oxidizers and corrosives?
Are acids and bases stored in separate, dedicated cabinets or areas?
Are water-reactive chemicals stored away from water sources and fire suppression systems?
Are compressed gas cylinders stored separately by hazard class (flammable vs. oxidizing)?
Is a chemical compatibility chart posted and visible in the storage area?
Are incompatible chemicals physically separated by distance or a barrier rated for the hazard class?

Container Integrity & Labeling

Inspect all containers for physical damage, proper closure, and compliant GHS labeling.

Are all chemical containers free from visible damage, leaks, or corrosion?
Are all containers labeled with the required GHS elements (product identifier, signal word, hazard pictograms, precautionary statements)?
Are secondary containers and portable containers labeled per GHS requirements?
Are containers stored in an upright position with caps, lids, or plugs tightly secured?
Are containers within their manufacturer-specified or regulatory shelf life limits?

Flammable & Combustible Liquid Storage

Evaluate compliance with flammable liquid quantity limits, cabinet standards, and ignition source controls.

Are flammable and combustible liquids stored in approved flammable storage cabinets (FM/UL listed)?
Do flammable storage areas have adequate ventilation (at least 1 cfm/sq ft or 6 air changes/hour)?
Are ignition sources (open flames, sparks, non-explosion-proof equipment) eliminated from flammable storage areas?
Are aggregate quantities of flammable liquids stored outside approved cabinets within NFPA 30 room limits?
Are bonding and grounding connections in place for flammable liquid transfer operations?

Secondary Containment & Spill Prevention

Verify that secondary containment systems are adequate, functional, and compliant with EPA SPCC requirements.

Is secondary containment in place for all oil and hazardous substance storage containers above EPA threshold quantities?
Is secondary containment free from cracks, holes, or accumulated liquid indicating prior release?
Are drain valves on secondary containment structures in the closed and locked position?
Are spill kits readily accessible and stocked with appropriate absorbents for chemicals stored in the area?
Is the floor of the storage area sloped toward containment drains or berms to prevent uncontrolled spill spread?

Ventilation & PPE Availability

Confirm that engineering controls and personal protective equipment are appropriate for the chemicals stored.

Is local exhaust ventilation (LEV) operational and inspected within the last 12 months?
Is appropriate PPE (chemical-resistant gloves, goggles, aprons) available and in serviceable condition at or near the storage area?
Is an eyewash station within 10 seconds travel time (approximately 55 feet) of the chemical storage area?
Is a safety shower available and accessible within the storage area for corrosive chemical emergencies?
Are air monitoring devices or gas detectors calibrated and operational where volatile chemicals are stored?

Emergency Response & Signage

Check that emergency contact information, hazard signage, and response procedures are posted and current.

Are NFPA 704 diamond hazard placards posted at all storage area entry points?
Are emergency contact numbers (internal safety, local fire department, CHEMTREC 1-800-424-9300) posted prominently?
Are evacuation routes from the chemical storage area clearly marked and unobstructed?
Is a fire extinguisher of the appropriate class (B:C for flammables) available and inspected within the past 30 days?
Has a chemical storage emergency response drill been conducted within the past 12 months?
