Lees’ Loss Prevention in the Process Industries, 4th Edition: Hazard Identification, Assessment and Control

Safety in the process industries is critical for those who work with chemicals and hazardous substances or processes. The field of loss prevention is, and continues to be, of supreme importance to countless companies, municipalities and governments around the world, and Lees’ Loss Prevention is a detailed reference to defending against hazards. Recognized as the standard work for chemical and process engineering safety professionals, it provides the most complete collection of information on the theory, practice, design elements, equipment, regulations and laws covering the field of process safety.


An entire library of alternative books (and cross-referencing systems) would be needed to replace or improve upon Lees’ Loss Prevention in the Process Industries, but everything of importance to safety professionals, engineers and managers can be found in this all-encompassing three-volume reference instead.

Key Features

  • The process safety encyclopedia, trusted worldwide for over 30 years
  • Now available in print and online, to aid searchability and portability
  • 3,776 print pages cover the full scope of process safety and loss prevention, compiling theory, practice, standards, legislation, case studies and lessons learned in one resource as opposed to multiple sources


Safety and loss prevention professionals; process and plant engineers; environmental and chemical safety professionals; in all chemical, petroleum and process industry sectors.
