    Many vehicular accidents happen because drivers are in too much of a hurry or they are distracted by any number of things. They just are not paying close enough attention to their surroundings. Traffic accidents at signalized intersections are common where both drivers claim the other driver is at fault.

    Facilities which utilize hazardous liquids and gases represent a significant potential liability to the owner, operator, and general public in terms of personnel safety and preservation of assets. It is obvious that a catastrophic incident or loss of property or personnel is to be avoided at all costs. This book was conceived to give the reader a guide to understanding the requirements of the various codes and regulations that apply to the design, construction, and operation of facilities utilizing hazardous materials in their processes.
