Fixed materials Materials which are in the factory area are chemically to a large extent. Due to our used raw materials above all materials with small grain size are of importance for the evaluation of the danger potential. With these materials the danger of a dust explosion exists with appropriate distribution in this case appropriate ignition sources are to be excluded and therefore these areas are to be defined as EX zones.
