Constructed using multiple layers of fire-resistant gypsum and mineral fiber insulation, the cabinet body has a rugged powder coated steel exterior that provides excellent corrosion resistance. Under fire conditions, intumescent strips expand and hermetically seal all gaps to reduce heat entering the cabinet, providing 90 minutes of content protection and extended evacuation time. Self-close style doors with hydraulic door-closer and integrated door open arrest system that keeps them open until they are pushed slightly out of the hold position. In the event of a fire, the built-in fusible link system releases to allow automatic closure of the doors at 118°F (47 °C).
Powder-coat finish steel shelves adjust on 1-1/4-inch (32-mm) increments and have a load capacity of 165-lbs (75-kgs). Shelves with 1-inch (30-mm) high ledge prevent small containers from easily sliding off. Removable bottom sump with detachable perforated insert features a 3-sided lip seal to ensure leaks or spills from shelves are captured at the bottom of the 3-inch (76-mm) sump, keeping containers stored in the sump clean and dry.
Haz-Alert™ reflective tri-lingual warning labels are highly visible under fire conditions or during power outages when illuminated with a flashlight. Independent cylinder locks on each door include a locking state indicator (red/green). Cabinets also feature adjustable leveling feet, an integrated transport base for easy repositioning (base cover optional), and mandatory air vents per EN 14470-1. Vent butterfly valve closes securely at 158°F (70°C) in the event of a fire. Vents include flame arresters and caps for FM approval.
Independently fire tested and approved by FM Approvals, and tested and GS certified by MPA Dresden, the cabinets are EN 14470-1 / EN 14727 compliant and meet NFPA 30, NFPA 1, and OSHA standards.
