Markings for Explosion Proof Equipment
Only EX, ATEX EX, and DX Equipment that has been tested and approved for use in Hazardous Classified Areas by the appropriate recognized testing laboratory can be marked accordingly.

Equipment approved for use in Hazardous Classified Areas must be designated with a specific marker.  All Explosion Proof Equipment must be clearly identified with the appropriate Marker and signs must be posted at the entrances to Explosion Proof environments.  Excalibur Miretti Group applies the appropriate EX, ATEX EX or DX marker to each piece of Explosion Proof Equipment in a prominent position.
