Abstract
A fire-resistant safe has a main body and a closure, both of which are formed from integral resin shells filled with insulation materials. When exposed to fire, a portion of the resin material burns away leaving gaps between the insulation materials of the main body and closure. However, formation of convection air currents in vertical sections of the gaps is resisted by reducing spacings between insulation materials of the main body and closure. The amount of heat energy carried by the convection air currents is similarly reduced, thereby avoiding significant concentrations of heat that can promote burning through the gaps.
