This book provides an advanced level of study of industrial hygiene engineering situations. Emphasis is on the control of exposure to occupational health hazards. Primary attention is given to industrial ventilation, noise and vibration control, heat stress, and industrial illumination. Other engineering topics covered include industrial water quality, solid waste control, handling and storage of hazardous materials, personal protective equipment, and costs of industrial hygiene control. The creation of this text came out of an attempt to design a course to teach the fundamentals of industrial hygiene engineering as related to the design of controls for exposure to health hazards in the workplace. The first objective of this text is to provide a single reference source on the subject of industrial hygiene engineering and control. The second objective is to provide the reader with a systematic approach to problem solving in the field of industrial hygiene. Throughout the text, the systems approach to problem solving is emphasized.
