Which processes are defined in Article 516?

Article 516 of the National Electrical Code (NEC) specifically covers spray application, dipping, and coating processes. These processes involve the use of flammable or combustible liquids, which necessitate unique safety measures to prevent hazards such as fire or explosions.

In such applications, it is crucial to understand and implement proper electrical installations to mitigate risks associated with the presence of ignitable vapors or mist. This article addresses the specific installation requirements, including the use of equipment rated for the hazardous locations that could be created during these operations.

The focus on spray application, dipping, and coating processes ensures that those working in environments where these processes take place are protected from electrical hazards associated with the volatile materials involved. Understanding this article equips industry professionals with knowledge of how to safely work with and around these processes.
