Abstract
Many of the nitrogen containing polymers produce HCN when involved in fires. Various methods of HCN determination in fire gases are reviewed. The methods discussed are colorimetric tubes, specific ion electrode, wet chemical analysis and gas chromatography. Two common problems in HCN determination are concentration decrease by absorption and interferring reactions. Authors recommend that at least two different methods be employed in order to avoid errors caused by interference and absorption.
