Flammable Liquid Storage Cabinet Inspection Checklist [FREE PDF]

Flammable liquid storage cabinets must comply with NFPA 30 Flammable and Combustible Liquids Code and OSHA 29 CFR 1910.106 to prevent ignition, fire, and explosion hazards in facilities storing Class I, II, or III liquids. Improper storage of flammable liquids is one of the most frequently cited OSHA violations, with deficiencies in cabinet design, quantity limits, and ventilation posing significant life-safety risks. Regular documented inspections are required under both OSHA standards and NFPA

Industry: Industrial Manufacturing
Frequency: Weekly
Estimated Time: 15-25 minutes
Role: EHS Manager
Total Items: 36
Compliance: OSHA 29 CFR 1910.106 Flammable Liquids Storage, NFPA 30 Flammable and Combustible Liquids Code (2021 Edition), OSHA 29 CFR 1910.1200 Hazard Communication GHS, EPA 40 CFR 112 Spill Prevention Control and Countermeasure (SPCC), NFPA 10 Standard for Portable Fire Extinguishers

Cabinet Construction & Design Compliance

Verify the physical cabinet meets NFPA 30 and OSHA construction specifications for flammable liquid storage.

Is the cabinet constructed of minimum 18-gauge steel with double-wall construction and 1.5-inch air space?
Does the cabinet bear a listing or approval mark from FM Global, UL, or equivalent recognized testing laboratory?
Does the cabinet door include a three-point latching mechanism and heat-activated fusible link or equivalent closing device?
Does the cabinet have a raised sill or lip of at least 2 inches to contain spills within the cabinet?
Is the cabinet prominently labeled with 'FLAMMABLE - KEEP FIRE AWAY' in letters at least 1 inch high?

Storage Quantity Limits & Classification

Verify stored quantities and liquid classifications comply with NFPA 30 and OSHA maximum quantity limits.

Is the total quantity of flammable liquids (Class I) in this cabinet at or below 60 gallons?
Is the total quantity of combustible liquids (Class II and III) in this cabinet at or below 120 gallons?
Are all liquids in the cabinet correctly identified as Class I (flash point below 100°F) or Class II/III (flash point 100°F and above)?
Are no more than 3 approved storage cabinets containing flammable liquids located in the same fire area without a 100-foot separation or firewall?
Is a current inventory log of chemicals stored in this cabinet maintained and up to date?

Ventilation, Grounding & Bonding

Inspect ventilation configuration and electrical bonding to prevent vapor accumulation and static discharge ignition.

Are both vent openings (top and bottom) either properly connected to a mechanical exhaust system or sealed with the manufacturer's bungs?
If the cabinet is mechanically ventilated, does the exhaust rate provide at least 1 cubic foot per minute per square foot of floor area with a minimum of 150 CFM?
Is the cabinet bonded and grounded to a verified earth ground with a resistance of less than 1 ohm?
Are all ignition sources (open flames, electrical switches, non-explosion-proof lighting) at least 5 feet from the cabinet?

Container Integrity & Labeling

Inspect containers inside the cabinet for leaks, damage, proper closures, and GHS-compliant labeling.

Are all containers inside the cabinet free from leaks, corrosion, dents, or damage that could compromise containment?
Are all container closures (caps, lids, bungs) fully tightened and functional with no evidence of vapor escape?
Are all containers labeled with a GHS-compliant label including product identifier, signal word, hazard pictograms, and hazard statements?
Are only approved safety cans used for quantities of 1 gallon or more of Class I flammable liquids?
Are containers of incompatible chemicals (e.g., oxidizers, acids) physically separated from flammable liquids in this or an adjacent cabinet?
Are containers returned to the cabinet promptly after use and never left open or unattended outside the cabinet for more than 3 minutes?

Fire Suppression & Emergency Equipment

Confirm appropriate fire suppression equipment is present, accessible, and current for the flammable liquid storage area.

Is a Class B dry chemical or CO2 fire extinguisher rated at least 20-B:C located within 10 feet of the cabinet?
Has the fire extinguisher been inspected within the past 30 days and serviced within the past 12 months?
Is an automatic sprinkler system or other fixed fire suppression system operational in this storage area?
Are fire suppression system control valves in the storage area in the open (normal operating) position and tagged or locked?
Is a flammable vapor detector or LEL monitor installed and functional in the cabinet storage area where mechanical ventilation is present?

Housekeeping & General Compliance

Assess overall storage area housekeeping, waste management, and general compliance posture.

Is the area around the flammable storage cabinet free from combustible materials (cardboard, paper, rags) within a 3-foot perimeter?
Are flammable liquid waste containers (used rags, wipes, contaminated materials) stored in approved, self-closing metal containers with lids?
Are 'No Smoking' and 'No Open Flame' signs posted at all entrances to the flammable storage area?
Has flammable liquid waste been collected and disposed of as hazardous waste within 90 days of accumulation start date?
Are all employees working in this area trained on flammable liquid hazards and the location of emergency equipment within the past 12 months?
Were any deficiencies or non-conformances identified during this inspection that require corrective action?

Corrective Actions & Sign-Off

Document identified deficiencies, corrective actions, responsible parties, and inspector certification.

Please describe all deficiencies identified during this inspection in detail (include cabinet ID, location, and specific non-conformance)?
Have immediate corrective actions (e.g., removal of excess quantity, re-labeling) been completed at the time of this inspection?
For deficiencies requiring deferred corrective action, has a target completion date been assigned and communicated to responsible personnel?
Please capture a photo of the cabinet exterior showing the labeling, door condition, and surrounding area?
Does the inspector certify that this inspection was conducted accurately and all findings have been documented completely?
