| Abstract | Several components in combustion products of polymers are known to be or are suspected of being harmful than CO for various conditions of combustion or thermal decomposition. HCN, one such compound produced from a variety of nitrogen containing polymers, is discussed in this paper. Published data for animal exposure studies in which HCN may have played a major role and quantitative data for HCN generation are reviewed. The conditions of combustion, such as temperature and amount of oxygen, that affect generation of HCN, are discussed. Theoretical calculation of the equilibrium concentration of HCN is also presented and discussed in relation to experimental data. Significance of HCN generation in fire gas toxicity is shown by using the toxicity factor. Ranking of nitrogen-containing materials based on the propensity of toxic gas generation can be variable because the quantity of HCN generated varies widely depending on the conditions of combustion. |
