Which processes are defined in Article 516?

Article 516 of the National Electrical Code specifically addresses the requirements for spray application, dipping, and coating processes. This article outlines the safety measures and electrical installations necessary to mitigate the risks associated with these processes, which often involve flammable liquids and vapors.

The rationale behind this focus is that during spraying, dipping, or coating, the use of volatile substances can create hazardous conditions, including the potential for ignitable mixtures in the air. Therefore, Article 516 provides guidelines on how to safely manage electrical systems and equipment in these environments to prevent fires and explosions.

The specifics of the code include provisions for grounding, bonding, and the use of specific electrical equipment rated for use in hazardous locations, ensuring the safety of both workers and the facility. Understanding the requirements of Article 516 is vital for professionals working in industries that utilize these processes to ensure compliance and safety in the workplace.
