"Since its first edition in 1951, Industrial Ventilation: A Manual of Recommended Practice has been used by engineers and industrial hygienists to design and evaluate industrial ventilation systems. The 27th edition of this Manual continues to be a basic reference. In developing the 26th Edition, the Industrial Ventilation Committee considered several new chapters for this manual. As the chapters developed, it became apparent that a reorganization of the Manual be desirable. Consequently two manuals were proposed and have been published: Industrial ventilation : a manual of recommended practice for design (referred to as the Design manual) addresses design of an industrial ventilation system and Industrial ventilation : a manual of recommended practice for operation and maintenance (referred to as the O&M Manual) was published as a separate manual and addresses operation and maintenance of ventilation systems."--P. vii.
