About This Item
IEEE 1349-2011 is a technical guide for applying electric motors in Class I, Division 2 and Class I, Zone 2 hazardous locations, with redline changes that help users identify revisions more efficiently. It addresses motor selection and application considerations where flammable gases or vapors may be present under abnormal conditions, making it relevant to power, energy, and industrial systems. For engineers and specifiers, this standard supports safer equipment decisions and more consistent installation practices in classified areas.
IEEE 1349-2011 overview
This standard provides guidance for the application of electric motors in hazardous locations classified as Class I, Division 2 and Class I, Zone 2. In that context, the document focuses on how motor characteristics, operating conditions, and installation practices should be considered to reduce ignition-related risk. As a redline edition, IEEE 1349-2011 is especially useful when comparing revisions and reviewing changes in technical requirements or guidance for classified-area motor applications.
Typical use cases
IEEE 1349-2011 is commonly consulted when selecting motors for process equipment, pumping systems, compressors, conveyors, and other rotating machinery installed in areas where flammable gases or vapors may occasionally be present. It can support engineering reviews, equipment procurement, and maintenance planning for facilities that use classified-area electrical systems. The guide is also useful when comparing motor options for compliance with site-specific hazardous-location requirements and application rules.
Why this standard matters
In hazardous locations, motor application decisions affect safety, reliability, and compliance. IEEE 1349-2011 helps teams apply a consistent technical basis when reviewing enclosure suitability, temperature considerations, duty, and installation constraints for classified areas. That can reduce the risk of improper equipment selection and simplify specification work across design and procurement. For organizations maintaining legacy or current installations, the standard also helps support documented decision-making and more controlled application practices.
