Electrical Safety in Flammable Gas/Vapor Laden Atmospheres

This book provides comprehensive coverage of electrical system installation within areas where flammable gases and liquids are handled and processed. The accurate hazard evaluation of flammability risks associated with chemical and petrochemical locations is critical in determining the point at which the costs of electrical equipment and installation are balanced with explosion safety requirements. The book offers the most current code requirements along with tables and illustrations as analytic tools. Environmental characteristics are covered in Section 1 along with recommended electrical installation and safety recommendations. Section 2 treats a number of application illustrations in detail. Section 3 presents examples for the application of classifying NEC Class 1 locations.
