share responsibility for overseeing respiratory protection in the workplace and have established regulations for this purpose. Specifically, NIOSH has issued regulations which define respirator testing and certification in 42 CFR 84 (National Institute for Occupational Safety and Health, June 2, 1995)

. This regulation does not specify how the face masks are to be designed, selected, and fitted to the various facial shapes and sizes, but historically NIOSH has certified respirators by testing them on panels of human subjects (Code of Federal Regulations, 2004)

Several studies add weight to this concern. In 1975, Leigh studied 1,467 Dow Chemical employees in the Atomic Energy Commission's Rocky Flats Plant in Colorado and found that 10.3 percent of half-face respirator users and 12.6 percent of full-face respirator users had measurements that fell outside the LANL face panel specifications (Leigh, 1975)

These panels were directly comparable with the panels based on the earlier LANL data, as each was based on the same pair of manually collected linear measurements used in the corresponding LANL face panel (e.g., Menton-Sellion length and lip length for the half-face panel)

. The committee's charge was to study the NIOSHsponsored Anthrotech study along with its supporting information and reports, and to examine and report on the adequacy and relevance of the study protocol, the analyses conducted, the resulting anthropometric dataset, and the appropriateness of the respirator fit-test panels derived from the new dataset.

• The committee will also examine how the data obtained from the study was analyzed, conclusions reached from the data, and recommend addi tional information that NIOSH might derive from current and possible fu ture efforts. Finally, the committee will suggest methods for translating the suggested respirator criteria derived from research into practice.
