Abstract |
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 field studies were conducted at foundries, an aircraft painting workshop and a steel mill. The protocol involves (1) collection of WPF samples at different parts of the shift; (2) collection of respirable dust samples; (3) washing of sample cassettes; (4) use of proton-induced X-ray emission analysis. WPF results after several hours of respirator use were generally higher than just after it was put on, but not significantly so. WPF estimation might be erroneous when respirable and total dust collection techniques are mixed. Data from cassette washing suggest that average wall losses for ambient and in-facepiece samples were <2% and ca. 6%, respectively. In appendix: notes on the selection of exposure agents, facilities, workers and respirators; respirator inspection and use; analytical and cassette washing methods used. |
