IN ONE SENTENCE
Zone 0 is continuously or frequently present, Zone 1 likely in normal operation, and Zone 2 unlikely and short-lived if it occurs.
In normal English
The zone is only one part of equipment selection; gas group, temperature class and protection method also matter.
Why would I use it?
Use it to match gas hazardous-area equipment to the classified location.
