Rigid control of contamination has contributed to the reliability and precision of vehicles and instruments sent out to explore space. Experience gained in the aerospace community also can be helpful in the pharmaceutical, electronic, and many other indus-tries in which extreme cleanliness is important. This is one of three Special Publi-cations issued by the NASA Office of Technology Utilization to help extend and diffuse current concepts and techniques of rigorous contamination control. The first of these documents, Contamination Control Principles, SP-5045, was issued in 1967 when a NASA Contamination Control Panel called attention to the wide-spread need for guideline information. The George C. Marshall Space Flight Center, the Manned Spacecraft Center, and the John F. Kennedy Space Center were represented on that panel by, respectively, Frederick J. Beyerle, Quintin T. Ussery., and Dr. John Gayle. Since then a number of special courses for technicians and supervisors employed in clean rooms have been given, and the lectures prepared by James W. Useller for one of those courses at the Lewis Research Center have been published in Clean Room Technology, SP-5074. This handbook deals in more detail with many of the same matters discussed i
