Previous edition: 2016. "This 30th ed of ACGIH's industrial ventilation: a manual of recommended practice for design, is to be used just as the name implies - A manual of recommended practices on the design og industrial ventation systems. This publication has been developed to serve as a guide to assist in the control of airborne contaminants that may pose occupational health hazard to employees."--Page vii Includes bibliographical references and index.

Since its first edition in 1951, Industrial Ventilation: A Manual of Recommended Practice has been used by engineers, regulators and industrial hygienists to design and evaluate industrial ventilation systems. Beginning with the 26th Edition, the Manual has undergone several major reorganizations and upgrades – the addition of a second compendium Manual dedicated to operation and maintenance; subsequent additions of chapters on organization and evaluation of systems; metric solutions and tables; and calculation sheets and methods. Now in its 30th Edition, changes in many of the chapters and conceptual figures that incorporate computational fluid dynamics (CFD) have been added for clarification and incorporated for simpler conceptual understanding of airflow patterns. Care has been taken to make this Manual a practical user’s handbook, written with deference toward a simpler and more concise means of explanation. In addition, the Manual incorporates a new control concept for vacuum extraction on welding guns to complement the four new conceptual design strategies found in the 29th Edition.
