dear maiduyson
electrical devices for use in hazardous area and manufactured within European Community must be "Ex" marked as well as provided with a Notified Body certificate.

Similar regulation exist worldwide with differences among countries; contact the local authority for details.

I can attach here a poster for a brief clarifications of what EC and USA use.
