What type of storage does Article 515 specifically address?

Article 515 of the National Electrical Code specifically addresses the requirements for bulk storage plants. This article outlines the safety provisions and electrical requirements necessary to ensure safe operation in facilities storing large quantities of flammable or combustible liquids.

The focus on bulk storage plants is critical because these environments present unique hazards due to the potential for spills, leaks, and vapors that can create explosive atmospheres. As such, the article includes guidelines for the installation of electrical equipment, wiring methods, and other safety measures to mitigate risks associated with these conditions.

The requirement for specific electrical systems and equipment in bulk storage situations aligns with the intent of the NEC to ensure safety in environments where hazardous liquids are stored in significant quantities. This approach minimizes the risk of ignition and helps protect both personnel and property.
