Electrical Instruments in Hazardous Locations

In this reference on electrical safety early chapters offer historical background and outline combustion and explosion fundamentals. Later chapters cover classification of hazardous locations and materials explosion-proof enclosures reduction of hazard by pressurization dust hazards and ignition of gases and vapors by electrical means. This fourth edition features expanded treatment of theory and principles to provide a foundation for addressing some of the questions that arise when no standard or regulation exists. There is a new chapter on increased safety and ignition by optical sources as well as more practical examples of applying principles in real situations including applications beyond North America. Discussion of CEN-ELEC standards is now distributed throughout the book according to subject matter. The chapter on flame arresters has been deleted from this edition. Annotation 2008 Book News Inc.
