舰艇舱室中7种非金属材料燃烧时烟雾中主要无机有害气体定量分析

目的 观察舰艇舱室中7种非金属材料燃烧或高温热解时,产生的烟雾中主要有害成分浓度变化,为救治中毒人员和采取防护措施提供依据.方法 将7种常用非金属材料在燃烧试验箱中燃烧,用检测仪器进行定量分析.结果 烟雾中氧气浓度低于安全浓度、一氧化碳和氰化氢浓度超过安全浓度.结论 烟雾气体缺氧以及一氧化碳和氰化氢浓度超标是导致人员中毒的主要因素.

Quantitative analysis of the smoke composition formed by the burning of 7 nonmetal materials within the naval vessel

Objective To study the smoke composition formed by the burning and high-temperature decomposition of 7 nonmetal materials within the naval vessel, changes in the concentrations of main toxic components in the smoke, and to provide scientific basis for the development of protective measures and treatment of casualties. Methods 7 commonly-used nonmetal materials were burned in the combustion chamber (or box), and then quantitative analyses were made on the components of the smoke. Results Oxygen concentration in the smoke was below safety limit and those of carbon monoxide and hydrocyanic acid were well above safety limits. Conclusions Low oxygen concentration and high levels of carbon monoxide and hydrocyanic acid in the smoke are the main causes for the intoxication of shipboard naval personnel.
