Before installing electrical equipment, accurate hazardous area classification is essential!

Determine the need for, and extent of, Class II (combustible dusts), Division area classification using this up-to-date Recommended Practice. With a specific focus on chemical manufacturing facilities, NFPA 499 contains detailed guidelines and diagrams that serve as useful tool for professionals who perform hazardous (classified) area classification for the purpose of selecting and installing electrical equipment that will not be an ignition source in environments where combustible dusts are produced, processed, or handled.

This document also provides extensive data on physical properties of selected materials, including specific Class II, Division dust group information. In the 2004 edition, definitions of hazardous (classified) locations parallel with the National Electrical Code®. Up-to-date with NFPA's Manual of Style.
