What to Specify Before Ordering Chemical Storage Cabinets

Begin with a chemical inventory. Record each substance, hazard class, container size, maximum quantity and storage temperature. Use the safety data sheet to identify incompatibilities and required segregation. For U.S. projects, review applicable facility procedures and the OSHA flammable liquids standard with the project safety team.

Next, define the cabinet type and construction. A flammable cabinet typically uses a double-wall steel structure, reinforced doors and liquid-tight containment features. PP cabinets are often selected for corrosive chemicals because the cabinet body resists many acid and alkali vapors. Toxic material storage may require controlled access, clear labeling and site-specific ventilation.

Ventilation should not be added automatically. Confirm whether the authority having jurisdiction, chemical risk assessment and facility policy require a vented or unvented cabinet. When ventilation is necessary, the duct material, exhaust rate and discharge location must be compatible with the stored chemicals. Improper connections can reduce cabinet performance or create a new exposure risk.

Finally, specify shelf quantity, adjustable spacing, load capacity, door type, lock, grounding point, leak containment and warning labels. Gas cylinder cabinets also need cylinder restraints, valve access and optional gas detection. LANDRO can manufacture custom safety cabinet dimensions and configurations for laboratories, universities, pharmaceutical facilities, chemical plants and industrial storage areas.
