ISA 12.02.02 : 2014

ANSI/ISA-12.02.02-2014, Recommendations for the Preparation, Content, and Organization of Intrinsic Safety Control Drawings, helps clarify the complex world of intrinsically safe control drawings by providing clear guidance on how to create and organize them. This standard outlines what information should be included, such as wiring diagrams, equipment details, safety parameters and location classifications, so anyone working with hazardous area systems can easily understand how different devices connect and operate safely. These drawings enable engineers and designers to specify and work with intrinsically safe equipment more confidently, saving time and reducing confusion during system design or review. This standard also emphasizes the importance of having accessible, well-organized drawings that clearly communicate critical safety details, promoting smoother collaboration among teams and suppliers.
