I had a question concerning zone selection in hazardous area classification:

 

in a plant, is it possible to have a zone 0 directly covered by zone 2?

A better formulation here would be:  is a jump among zones is allowed?   that means for example having a zone 2 adjacent to zone 0?,   or a non-hazardous area directly adjacent to zone 1? 

 

Thanks in advance
