Electrical equipment fires, explosions, and other dangers relating to the ignition of a flammable atmosphere pose a significant threat to life and property. Help identify and minimize potentially deadly hazards and better safeguard facilities by referencing and complying with NFPA 496, Standard for Purged and Pressurized Enclosures for Electrical Equipment.

This critical standard offers protection techniques applicable to Class I and Class II locations. You get comprehensive criteria for designing and operating purged and pressurized electrical equipment enclosures to minimize hazards in the presence of flammable materials.

2024 Changes include:

• Annex has been added to clarify that power to a protective gas supply must be activated regardless of whether there is power to a protected enclosure and the equipment within the enclosure.
• Definition for hazardous (classified) locations has been added from the NEC.
