Answer / mpf

You probably mean on explosion hazard zones. Most of
instrumentation equipment falls in the category of intrinsic
safety ("i") and therefore can be placed in all zones (with
some limitations to zone 0) being zone 0 the most strict zone
where exploding substance is always present and zone 2 - the
least strict zone where the potentialy exploding substance
could be present in short periods of time in case of an
failure. Otherwise, if the equipment is not of "i" type of
protection, other rules apply.
