All we know hazardous area classification is a must have.

Question to here: how you mark the Ex zone?

– ATEX says Ex mark shall be displayed?!

– painting on floor?

– signs?

– warnings?

– zone map in the hand?


– Ex only does not say which group and T class, so not easy to identify if the installation is good or not (meeting the EPL requirements)

Recommendation: besides the Ex mark E.g Zone 1 IIB T4 to display, and then all easy to follow up.

Keep up good work!
