As per IEC Standards, the areas where explosive dusts may be present are categorized into three groups: Zone 20, Zone 21, and Zone 22. This animation is about Zone 20.
Zone 20 is defined as an area in which an explosive dust atmosphere, in the form of a cloud of dust in the air, is always present during normal operation. As a result, electrical or non-electrical equipment used in Zone 20 must not become a source of ignition in the form of hot surfaces or sparks under normal or even abnormal conditions.
