- Abstract
- This report describes the different analytical procedures used for the main gases given off or present in fire effluents: carbon monoxide (CO), carbon dioxide (CO2), oxygen (O2), nitrogen oxides (NOx), hydrogen cyanide (HCN), hydrogen chloride (HCl), hydrogen bromide (HBr), hydrogen fluoride (HF) and acrolein. The analysis of gases in fire effluents represtnts a very specialised field of study due to the complexity and reactivity of the gas mixtures. Scientists from different countries have developed new or have adopted existing analytical methods in accordance with their own requirements. A working group has been created by the sub committee 3/TC 92 (Toxic Hazards in Fire) of International Organisation for standrdisation in order to establish international standards of analytical techniques for fire effluents. The analysis of gases in fire atmospheres is very complex due not only to the great number of different organic and inorganic species which may be present, but also due to difficulties in sampling representative atmosphere for measurement. The test environment, sampling contraints, analytical range and accuracy often dictate use of one analytical method over another.
