negligible hazardous area – what means negligible?

“in some cases a zone of negligible extent (NE) may arise and may be treated as non hazardous. such a zone implies that an explosion, if it takes place, will have negligible consequences.” – cut out from iec 60079-10-1

finally there an explosion may happen. how shall we react on that?

if we ignore all possible ignition sources, this is a solution? still there is a need of Ex certified installations?

or better to ignore the term negligible?

few points to consider before acting on hazardous area classification.

keep up good work!
