A compliant AS1940 flammable cabinet is specifically engineered to slow the transfer of heat into the cabinet interior during a fire, preventing stored vapours from reaching ignition point long enough for occupants to evacuate and emergency services to respond. The key construction features in the Justrite range are:
| Feature | Specification | Purpose |
|---|---|---|
| Double-wall steel construction | 1.2mm steel walls with 40mm insulating air gap | Thermal barrier - slows heat transfer to cabinet interior during fire exposure |
| Self-closing door mechanism | Concealed roof-mounted self-close; adjustable speed; fusible link melts at 74°C | Automatically seals cabinet shut under fire conditions, cutting off oxygen supply |
| 3-point self-latching door system | Stainless steel bullet latches at top, centre, and bottom | Ensures doors seal fully closed under fire-induced warping |
| Flame arresters on vents | Built-in steel flash arresters on vent positions | Prevents external flame from propagating into the cabinet through vent holes |
| Spill containment sump | Leakproof welded sump | Contains spills and leaks inside the cabinet, preventing liquid from reaching ignition sources |
| Grounding connector | External static earth connection point | Dissipates static charge build-up - a key ignition risk when decanting flammable liquids |
| Powder coat finish | Electrostatic powder coat, 190°C oven-baked | Resists solvents, acids, and alkalis; protects against chemical vapour corrosion |
