 · This level of risk is represented by classifying the hazardous area as Zone 0 Zone 1 or Zone 2 for gas vapour and mist atmospheres or Zone 21 or Zone 22 for dust atmospheres In this article we will look at what defines Zone 0 Zone 1 and Zone 2 hazardous area classifications and the considerations for specifying lighting into each area, But first, we must consider what is likely to cause an explosion in the first place,

 · Depending on the presence of combustible dusts or ignitable fibers and flyings the hazardous area is classified in three zones: Zone 20 Zone 21 and Zone 22 In both the above zone classification the probability of explosion severity reduces when we move from zone 0 or zone 20 to zone 2 zone 22,
