Hazardous Locations

International Association of Electrical Inspectors (IAEI)

For fire or an explosion to occur, three things must be present at the same time: Oxygen to sustain combustion; Heat to raise the material to its ignition temperature; and Fuel or combustible material. Oxygen, heat, and fuel are called the fire triangle. Take any of these three things away, and you will not have a fire or an explosion.

Essentially, hazardous locations code rules focus on keeping fuel sources separated from ignition sources (electrical current). This involves removal of at least one leg of the fire triangle. This text reveals how this is done—carefully and methodically. Through photos, illustrations, and thorough explanations, the reader will learn how to safety-proof the most hazardous locations.

The intent of this book is to provide training material and resources for students in the classroom or seminar setting and to assist those involved with designing, installing, inspecting and maintaining electrical systems in hazardous (classified) locations. It includes information on area classification, methods of protection, inter-action of protection techniques with specific types of electrical equipment, wiring requirements, and information on specific occupancies and industries.
