Evaluation of fire gases from polymeric materials

This paper presents and discusses the toxicity of the products of combustion in terms of small molecular species arising when a sample of a material is completely burnt in excess air under specified conditions. The evaluation of the toxicity is made through the determination of the following gases: Carbon oxides, halogen acids, Prussic acid, nitric oxides, acrylonitrile, phenol, phosgene etc. Cable sheathing materials, combustible materials like fibre reinforced plastic used in rail coaches for interiors: the floors, side wall, window frames etc and floor covering materials: Nylon carpets, styrene butadiene rubber mats; Curtains, Drapes, seat cushioning materials/covering materials have been evaluated. The results are presented and discussed.
