What type of storage does Article 515 specifically address?

Article 515 of the National Electrical Code (NEC) specifically addresses the storage of flammable liquids in bulk storage plants. This article outlines the requirements for safely storing these materials to minimize fire and explosion hazards. Flammable liquids are classified based on their flash points, and Article 515 includes provisions for the electrical installations and equipment in areas where these liquids are stored.

The emphasis on bulk storage is crucial as it involves larger quantities of flammable liquids, which present significant risks. The regulations established in this article help ensure that the electrical systems are designed and installed in a way that reduces the likelihood of ignition sources in proximity to the stored flammable materials.

Understanding the provisions of Article 515 is essential for professionals working in environments where bulk flammable liquids are stored, as adherence to these guidelines can lead to safer operations and compliance with legal requirements.
