About This Item
IEEE P1349/D9.4, Jun 2011 is a draft guide for applying electric motors in Class I, Division 2 and Class I, Zone 2 hazardous locations. It focuses on motor selection and application where flammable gases or vapors may be present under abnormal conditions, making safe design and installation decisions especially important. For power, energy, and industrial applications, this technical document helps frame practical requirements for motor use in potentially hazardous areas while supporting more consistent engineering review and compliance planning.
What is IEEE P1349/D9.4, Jun 2011?
IEEE P1349/D9.4, Jun 2011 is an IEEE draft guide intended to address how electric motors should be applied in hazardous classified locations, specifically Class I, Division 2 and Class I, Zone 2 environments. Its technical context is the safe use of motors where ignitable concentrations of gas are not normally present, but may occur under fault or unusual conditions. The document is relevant to engineering teams that need guidance on equipment suitability, installation considerations, and application controls for these locations.
Where is IEEE P1349/D9.4, Jun 2011 used?
This guide is used in industrial facilities and systems where motors may operate near process areas with combustible gases or vapors, such as chemical handling, fuel-related operations, and similar hazardous-area installations. It may also apply in transportation-related equipment and supporting infrastructure where classified locations are part of the design. IEEE P1349/D9.4, Jun 2011 is most useful during equipment specification, procurement review, and installation planning for motor-driven machinery in these environments.
Why is IEEE P1349/D9.4, Jun 2011 important?
IEEE P1349/D9.4, Jun 2011 matters because hazardous-location motor applications require careful control of ignition risk, installation practice, and equipment suitability. A clear guide helps engineers and buyers compare motor options more consistently and reduces uncertainty during design review and compliance work. In practice, it can support safer procurement decisions, better documentation, and more reliable application of motors in areas where classified-location requirements affect performance and risk.
