Fundamental Study of Gas Toxicity with Respect to Fire Stages

Abstract

Current Building Standard Law of Japan estimates fire toxicity of building material in case of fire by gas toxicity test using mice. Because it is an animal test, some problems are identified such as the impossibility of quantitative analysis, and from ethical viewpoints. Gas analysis method is needed as an alternative. In this research, authors report FTIR (Fourier Transform Infrared Spectroscopy) analysis of gases generated from building materials using gas toxicity test equipment and a tube furnace. The possibility of replacing animal test with FTIR gas analysis test was discussed.
