This book provides a comprehensive overview of hazardous areas containing explosive gases, vapors, and combustible dust. It also discusses about the different types of protection techniques used in explosion-proof electrical equipment. This book further provides guidance on how to deal with electrical explosions caused by fires due to arcs and sparks caused by a failure in the design, manufacture, selection, installation, or maintenance of electrical equipment. Among the topics covered in this book are overview of hazardous areas, various types of protection available, mechanisms for explosion pressure to build inside flameproof enclosures, concept of preventing explosions in flammable and dusty environments, unique features of explosion-proof motors, process of testing and certifying explosion-proof equipment in India and abroad, and mechanisms for the initiation and prevention of explosions resulting from non-electric sources. The book also discusses topics such as the selection, installation, inspection, and maintenance of electrical equipment. In addition, this book will be useful for researchers and professionals working in the fields of electrical engineering, mechanical engineering, petroleum engineering, mining engineering, and testing laboratories that test and certify explosion-proof equipment.
