Acknowledgements
The initial development of this document was performed under an interagency agreement between NIOSH and Los Alamos Scientific Laboratory (now Los Alamos National Laboratory) with John A. Pritchard as the author.
We would like to express our gratitude to Samuel L. Terry for information on atmosphere-supplying respirators, Christopher Coffey for information on air-purifying respirators, Nancy Morgan for her word processing support, and Howard Ludwig for his review.
In addition, we would like to thank the respirator manufacturers who provided National Institute for Occupational Safety and Health (NIOSH) with pictures of their products to be used as illustrations, and the American National Standards Institute Z88.2 Respirator Committee, and the American Industrial
Hygiene Association Committee on Respirators for their technical review of the document.
A special thanks goes to Herb Linn for his editorial review, art work, document preparation, and cover design.
