Flammable chemical cabinet specifications ensure fire resistance (10-90 mins), usually via double-walled steel construction, yellow color, and proper labeling ("Flammable-Keep Fire Away"). Key specs include capacities (4-90 gal+), self-closing or manual doors, adjustable shelves, leakproof sumps, grounding, and compliance with OSHA/NFPA standards, with options for venting in fume hoods but generally not for standalone units. 

Key Specifications

• Construction: Double-walled steel (18-gauge recommended) with insulating air space for fire resistance.
• Color: Typically Yellow for flammables, though red is used for paints/inks, blue for corrosives, etc..
• Doors: Self-closing (preferred) or manual-closing, with self-latching mechanisms.
• Labeling: Clearly marked "Flammable-Keep Fire Away".
• Shelves: Adjustable, galvanized steel, with a leakproof sump (e.g., 2-inch deep) to contain spills.
• Capacity: Ranges from small benchtop (e.g., 4 gal) to large (e.g., 90 gal or more).
• Venting: Optional; vents with flame arresters connect to fume hoods, but free-standing units usually remain unvented.
• Grounding: A built-in grounding connector is often included. 

Key Specification Areas

1. Cleanliness & Air Quality:
   • ISO Classification: ISO 6 (Class 1000) to ISO 9 (Class 100,000 or higher).
   • Filtration: HEPA (99.97% @ 0.3µm) or ULPA filters via Clean Air Modules (CAMs) or Fan Filter Units (FFUs).
   • Air Changes: 20-180+ Air Changes per Hour (ACH), depending on class.
   • Airflow: 18-32 CFM/sq ft for higher classes, ensuring unidirectional or mixed flow.
   • Pressure Control: Differential pressure monitoring (Magnehelic gauges) for airlocks.
