Overview
The Titan SCB-90 is a UL-listed and FM-approved 90-gallon (340 L) safety cabinet engineered specifically for the secure storage of weakly corrosive liquids—including diluted acids (e.g., acetic, phosphoric, nitric <10%), alkaline solutions (e.g., sodium hydroxide <10%), and halogenated solvents—in laboratory, pharmaceutical QC, and industrial R&D environments. Unlike general-purpose flammable liquid cabinets, the SCB-90 integrates chemically resistant construction—featuring 1.2 mm thick double-walled steel with polyurethane foam insulation—and interior components fabricated from epoxy-coated steel and corrosion-resistant stainless-steel hardware. Its design complies with OSHA 29 CFR 1910.106, NFPA 30 Chapter 9, and ANSI Z358.1 for secondary containment integrity, while the self-closing, three-point latching door meets fire-resistance requirements for 10-minute exposure at 1,000°F (538°C). The cabinet is not rated for strong oxidizers or hydrofluoric acid; users must consult SDS compatibility prior to installation.
Key Features
- Double-wall construction with 40 mm polyurethane insulation for thermal stability and structural rigidity
- Epoxy-powder-coated interior surfaces and stainless-steel shelf supports resisting pH 2–12 exposure for ≥72 hours per ASTM D1308
- Self-closing, self-latching 180° swing door with automatic closure triggered at 165°F (74°C) via fusible link
- Integrated 2-inch (51 mm) leak-proof sump capable of retaining 100% of the largest container volume plus 10% freeboard—exceeding EPA 40 CFR 264.175 secondary containment mandates
- Adjustable galvanized steel shelves with 35 kg (77 lb) uniform load capacity per shelf; rear-mounted shelf clips prevent lateral displacement during seismic events
- Grounding lug pre-installed for mandatory static dissipation in accordance with NFPA 77 and IEC 61340-5-1
Sample Compatibility & Compliance
The SCB-90 is validated for long-term storage of weakly aggressive reagents commonly used in analytical chemistry, formulation labs, and quality control workflows—including buffer solutions, titrants, cleaning agents, and low-concentration etchants. It is incompatible with concentrated mineral acids (>20% HCl, >30% H₂SO₄), anhydrous HF, molten alkalis, or peroxide-forming solvents. All materials contacting stored liquids—including drip trays, shelf liners (optional), and gasketing—meet USP Class VI biocompatibility standards and pass ISO 10993-5 cytotoxicity testing. Documentation includes factory-certified weld integrity reports, sump retention test records, and third-party fire-rating certification (UL 1275, FM 6050).
Software & Data Management
As a passive containment system, the SCB-90 does not incorporate embedded electronics or software. However, it is fully compatible with enterprise-level laboratory inventory management platforms (e.g., LabVantage, Quartzy, and Thermo Fisher SampleManager) via standardized barcode label fields on the front panel. Optional accessories include RFID-enabled door latch modules (sold separately) that interface with building BMS systems for access logging and audit trail generation compliant with FDA 21 CFR Part 11 Annex 11 requirements. Calibration and maintenance logs are maintained manually using Titan’s GxP-aligned checklist templates—available in English and aligned with ISO/IEC 17025 clause 8.7.
Applications
- Secure staging of corrosive reagents prior to HPLC mobile phase preparation in QC laboratories
- Storage of etching solutions (e.g., buffered oxide etch, dilute HF blends) in semiconductor pilot-line cleanrooms
- Containment of neutralizing agents and spent electrolytes in battery R&D facilities
- Secondary containment for dispensing stations handling chlorinated solvents in GLP-regulated environmental testing labs
- Compliant storage of disinfectant concentrates (e.g., diluted sodium hypochlorite) in hospital central supply departments
FAQ
Is the SCB-90 certified for use in EU laboratories under ATEX or DSEAR regulations?
No—the SCB-90 is not explosion-proof and lacks ATEX certification. It is intended for non-hazardous area use where vapors remain below LEL thresholds; supplemental ventilation per EN 14175 is required if used with volatile weak acids.
Can I retrofit the cabinet with internal LED lighting or temperature monitoring?
Titan offers factory-integrated options including intrinsically safe LED strips (IECEx certified) and NIST-traceable RTD probe ports—but field modifications void fire-rating certification and UL listing.
Does the sump meet SPCC regulatory requirements for aboveground storage?
Yes—the 2-inch sump exceeds EPA SPCC Rule 40 CFR 112.8(c)(2) minimum capacity mandates for containers ≥55 gallons; full compliance requires site-specific secondary containment assessment by a PE.
What is the recommended maintenance interval for hinge lubrication and gasket inspection?
Titan specifies quarterly visual inspection of door gaskets per ASTM D2000 and annual hinge lubrication using silicone-based grease (MIL-G-6032E); log entries must be retained for 5 years under ISO 9001:2015 clause 8.5.2.
