IEST publishes updated contamination control RP on Personnel Practices and Procedures in Cleanrooms and Controlled Environments

April 14, 2006 — /IEST/ — ROLLING MEADOWS, Ill. — The Institute of Environmental Sciences and Technology (IEST) has issued Contamination Control Recommended Practice IEST-RP-CC0027.2, Personnel Practices and Procedures in Cleanrooms and Controlled Environments. This updated Recommended Practice (RP) provides a basis for establishing personnel procedures and the development of training programs for cleanrooms and other contamination-controlled environments.

People and their street clothing are a significant source of cleanroom contamination. An effective contamination control system should be adopted to minimize the risks to the product, process yields, and cleanroom environment. Operational protocols should be established to maintain the proper controls.

IEST-RP-CC027.2 serves as a guide for developing a program to manage contamination caused by or associated with the people, processes, and tooling in the cleanroom. The document provides a general description of the elements essential to a contamination control program as well as specific procedures for minimizing human-sourced contamination. The rationale behind the procedures and elements is discussed. A diagram of a sample ISO Class 4 cleanroom illustrates traffic flow patterns to help minimize contamination.

Founded in 1953, IEST is an international technical society of engineers, scientists, and educators that serves its members and the industries they represent (simulating, testing, controlling, and teaching the environments of earth and space) through education and the development of recommended practices and standards.

IEST is an ANSI-accredited standards-developing organization; Secretariat of ISO/TC 209 Cleanrooms and associated controlled environments; Administrator of the ANSI-accredited US TAG to ISO/TC 209; Administrator of the ANSI-accredited US TAG to ISO/TC 142 Cleaning equipment for air and other gases; and a founding member of the ANSI-accredited US TAG to ISO/TC 229 Nanotechnologies.
