Abstract

The article describes and analyses toxic substances produced during a combustion of plastics which affect human health. Accidents and emergencies resulting from the combustion of plastic materials occur very often during the industrial production and technological processes. The authors illustrate this fact using the most recent example - the fire in the manufacturing and logistics premises in Chropyne, the Czech Republic, during which the professional as well as volunteer firefighters and the specialized fire rescue service units were employed.

Highlights

  • In the environment, in industry, motorism, aviation and in many other key industries a wide range of substances with various chemical properties is used

  • Plastic materials have become an indespensable part of our lives

  • Products made of plastic are used in building

Summary

Introduction

In industry, motorism, aviation and in many other key industries a wide range of substances with various chemical properties is used. The dangerous factors during firefighting are: G elevated ambient temperature, G excessive formation of smoke, G decrease in oxygen content in the air and G toxic products of fire. A conflagration produces a wide range of toxic substances Their properties and their quantity depend on the original properties of the combustible matter. A table describing the immediate lethal doses of each of the toxicants most frequently produced by conflagration represents an important part of this chapter. As it has already been stated, during a fire, numerous new compounds are created (as the intermediate products or as the end products of combustion). Their toxic properties can be found in the the following text as well as in the table below

Toxic properties of carbon compounds produced by a fire
NH3 ϩ 3 O2 ϭ 2 N2 ϩ 6 H2O
