Hazardous Location Equipment

Regardless of the cause of a hazardous location, it is necessary that every precaution be taken to guard against ignition of the atmosphere. Electrical equipment can be a potential source of ignition.

Hazardous location equipment is designed and constructed to eliminate the potential for ignition of the atmosphere.

The National Electrical Code is the "Bible" of the electrical industry, and the primary source of reference for hazardous locations. The NEC is also the basis for OSHA Standard 1910.307, Hazardous (Classified) Locations. There are several
OSHA standards that require the installation of electrical wiring and equipment in hazardous (classified) locations according to the requirements of Subpart S, Electrical. The NEC should be consulted as a supplement to the OSHA standards for additional background information concerning hazardous locations.
