Overview

• Consists of different types of protection techniques used in explosion-proof electrical equipment
• Discusses frictional hazards caused by coal-cutting picks striking a hard rock in coal seams in underground mines
• Provides guidance on how to deal with electrical explosions caused by fires

About this book

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.
