Summary:
As automation pushes motors and equipment into areas bordering hazardous zones, the article argues for proportionate specification—selecting only the level of hazardous-location protection that the real risk, duty, and environment warrant. Right-sizing helps prevent ignition while avoiding the cost, complexity, and performance penalties of over-specifying; it depends on accurate area classification, understanding materials and thermal behavior (including drive effects), and close coordination across safety, process, and electrical teams throughout the lifecycle.
