Product Details

Model EPWN Enclosure Pressurization Warning Nameplate 

This nameplate is intended for all protected enclosures. One (1) nameplate is furnished with all Pressurization and Purging Units, but additional nameplates must be ordered separately at time of order to label all doors of the protected enclosure, as required by NFPA 496.

The Model EPWN nameplate is an essential accessory and required by NFPA 496 to ensure operators and maintenance personnel are advised that they must not open the protected enclosure while internal devices that are not suitable for use in the Hazardous Area are energized. To meet protected enclosure labeling requirements for both Class I and Class II, the warning also prescribes that all combustible dust must be removed from the protected enclosure and it must be properly purged or pressurized after it is opened, before re-energizing any internal devices that are not suitable for use in the Hazardous Area.
