PREFACE This work is the result of a collaborative scientific effort between Anthrotech, Inc. and the National Institute for Occupational Safety and Health (NIOSH), NPPTL/Pittsburgh Research Laboratory. The project’s main goal was to create a data base of anthropometric information – both traditional and 3D – that could be used for respirator design in the decades to come. A project of this magnitude could not be accommplished without the efforts of many persons. We are grateful to Dr. Ziqing Zhuang, NPPTL/PRL, for his leadership and the vision to see the long-term goal. We visited 41 sites in 8 states. The cooperation of the liaison at each of those sites was critical to the success of the effort. Those individuals are too numerous to name here, but we are deeply in their debt. They have, of course, been thanked individually. We are also indebted to the more than 4000 subjects who gave of their time to assist in this effort. They recognized the importance of the work we were doing, and played an important part. Finally, the authors thank Belva Hodge, Shirley Kristensen and Ilse Tebbetts of Anthrotech, as well as several summer interns for their efforts in completing the project. v
