Smoke and toxic gas production by enclosed shipboard fires is modeled in a six x six x six ft fire chamber in which fuelbed and ventilation parameters can be readily adjusted. Smoke is characterized primarily by obscuration characteristics and the toxic gas so far investigated is carbon monoxide CO. For runs to date the fuel has been kerosene, although many other fuels and fuel combinations can and will in the future be burnt. An important experimental observation was the coupling between volumetric flow increase due to heating and system ventilation. It is conjectured that such coupling could lead to unexpected smoke accumulation from shipboard fires. The fire chamber has been adapted to make possible controlled application of water spray, carbon dioxide and Purple K from an easily changeable location. Results of a series of pilot fire suppression runs are presented.
