Correlations of hydrogen chloride and hydrogen cyanide and hydrogen cyanide concentrations evolved during combustion of chlorine- and nitrogen-containing materials.
Pittsburgh, PA: U.S. Department of the Interior, Bureau of Mines, RI 9521, 1994 Apr; :1-14
The U.S. Bureau of Mines conducted a study to determine if correlations exist between the chlorine or nitrogen contents of materials and the hydrogen chloride (HCI) or hydrogen cyanide (HCN) concentrations evolved during the thermal decomposition of these materials. HCI, HCN, and carbon monoxide (CO) were found to be the primary toxic gases evolved during the combustion process. The data indicate that there are significant correlations between the percentage of chlorine or nitrogen contained in the original samples and the HCI or HCN concentrations evolved during the combustion of the materials. These correlations may be used to predict and evaluate a material's toxic hazard during combustion.
