| Abstract |
This test program evaluated the effectiveness of carbon dioxide in extinguishing, controlling, and containing deep-seated Class A cargo fires. Tests were conducted to: identify a Class A test fuel closely simulating cotton without its high cost; determine an ignition source for creating and reproducing standard deep-seated fires; create deep-seated fire scenarios in single bales of cardboards test fuel for comparison with, and modeling of, full-scale cargo hold tests; and, determine extinguishment, control, and confinement concentrations of carbon dioxide for Class A cargo hold fires. The results indicated that: corrugated cardboard with its low cost and rapid, sustained fire buildup represented the best Class A fuel substitute for cotton; electric (charcoal) ignitors (120V, 525W) were found to maintain high, reproducible test temperatures inside the bales; the single-bale chamber tests created model fire scenarios comparable to the full-scale tests for comparing time temperature curves and investigating the effects of different agent concentrations; the extinguishment of a deep-seated Class A cargo hold fire at sea is highly unlikely using the quantity of carbon dioxide which a vessel can economically carry; a carbon dioxide concentration of twenty-five percent or greater will, however, extinguish the superficial flames created by a deep-seated fire, and, this concentration will also contain and control the smoldering combustion to a rate which will not endanger the structural integrity of the vessel. |
