Which article would you refer to for spray application processes?

The correct choice, Article 516, pertains specifically to spray application processes. This article addresses the requirements and standards necessary for safely working with materials that are applied using spray techniques, which can involve flammable and combustible materials. It provides guidelines on the types of equipment to be used, the environment in which spraying is allowed, and safety measures that must be considered to prevent hazards associated with overspray, fumes, and the potential ignition of flammable aerosols.

By understanding the mandates set forth in Article 516, electricians and those involved in spray application can ensure compliance with relevant safety and performance standards, thereby minimizing risk and enhancing the effectiveness of their work. The distinctions between this article and others, such as Articles 514, 518, and 520, emphasize different aspects of electrical installations and equipment, making it crucial to refer to the correct article for specific processes like spray applications.
