      <subfield code="a">This article presents the research protocol used for a series of field studies that were conducted to measure workplace protection factors (WPF) for elastomeric and disposable half-facepiece respirators against particulate contaminants. The protocol was used for studies at three brass foundries, an aircraft painting operation, and a steel mill sinter plant. Particulate contaminants evaluated in these industries-operations included various metal dusts and fumes and paint overspray that included metallic pigment. In this article findings are reported on aspects of the sampling and analytical methodology that were employed for the first time in these studies</subfield>
