---------------------------------
Zones: Hazardous areas are classified into zones based on the likelihood of an explosive atmosphere:
Gas/Vapor/Mist (Zones 0, 1, 2):
Zone 0: Explosive atmosphere present continuously or for long periods (>1000 hours/year).
Zone 1: Explosive atmosphere likely to occur occasionally (10–1000 hours/year).
Zone 2: Explosive atmosphere unlikely or short duration (<10 hours/year).
Dust (Zones 20, 21, 22):
Zone 20: Explosive dust cloud present continuously or frequently.
Zone 21: Explosive dust cloud likely during normal operation.
Zone 22: Explosive dust cloud unlikely or brief.
Equipment Categories:
Category 1: Suitable for Zone 0/20 (very high protection).
Category 2: Suitable for Zone 1/21 (high protection).
Category 3: Suitable for Zone 2/22 (normal protection).
Marking: ATEX-certified equipment carries a label, e.g., Ex II 2G Ex db IIC T4 Gb:
Ex: Explosion-proof.
II: Equipment group (II for non-mining, I for mining).
2G: Category 2, suitable for gas (Zone 1).
Ex db: Protection method (e.g., flameproof enclosure).
IIC: Gas group (IIC covers highly ignitable gases like hydrogen).
T4: Temperature class (max surface temp 135°C).
Gb: Equipment protection level (suitable for Zone 1).
