The objective of this study was to identify risk factors associated with BeS to inform the prevention of sensitization, and the development of chronic beryllium disease (CBD).<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In a survey of short-term workers employed at a primary beryllium manufacturing facility between the years 1994\u20131999, 264 participants completed a questionnaire and were tested for BeS. A range of qualitative and quantitative peak inhalation metrics and skin exposure indices were created using: personal full-shift beryllium exposure measurements, 15 min to 24 h process-specific task and area exposure measurements, glove measurements as indicator of skin exposure, process-upset information gleaned from historical reports, and self-reported information on exposure events. Hierarchical clustering was conducted to systematically group participants based on similarity of patterns of 16 exposure variables. The associations of the exposure metrics with BeS and self-reported skin symptoms (in work areas processing beryllium salts as well as in other work areas) were evaluated using correlation analysis, log-binomial and logistic regression models with splines.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Metrics of peak inhalation exposure, indices of skin exposure, and using material containing beryllium salts were significantly associated with skin symptoms and BeS; skin symptoms were a strong predictor of BeS. However, in this cohort, we could not tease apart the independent effects of skin exposure from inhalation exposure, as these exposures occurred simultaneously and were highly correlated. Hierarchical clustering identified groups of participants with unique patterns of exposure characteristics resulting in different prevalence of BeS and skin symptoms. A cluster with high skin exposure index and use of material containing beryllium salts had the highest prevalence of BeS and self-reported skin symptoms, followed by a cluster with high inhalation and skin exposure index and a very small fraction of jobs in which beryllium salts were used. A cluster with low inhalation and skin exposure and no workers using beryllium salts had no cases of BeS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Multiple pathways and types of exposure were associated with BeS and may be important for informing BeS prevention. Prevention efforts should focus on controlling airborne beryllium exposures with attention to peaks, use of process characteristics (e.g. the likelihood of upset conditions to design interventions) minimize skin exposure to beryllium particles, and in particular, eliminate skin contact with beryllium salts to interrupt potential exposure pathways for BeS risk.<\/jats:p><\/jats:sec>","DOI":"10.1093\/annweh\/wxz064","type":"journal-article","created":{"date-parts":[[2019,7,24]],"date-time":"2019-07-24T11:08:51Z","timestamp":1563966531000},"page":"856-869","source":"Crossref","is-referenced-by-count":9,"title":["Associations of Metrics of Peak Inhalation Exposure and Skin Exposure Indices With Beryllium Sensitization at a Beryllium Manufacturing Facility"],"prefix":"10.1093","volume":"63","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5916-4611","authenticated-orcid":false,"given":"M Abbas","family":"Virji","sequence":"first","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christine R","family":"Schuler","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"},{"name":"National Institute for Occupational Safety and Health, Division of Safety Research, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jean","family":"Cox-Ganser","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marcia L","family":"Stanton","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael S","family":"Kent","sequence":"additional","affiliation":[{"name":"Materion Brush Incorporated, Elmore, OH, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kathleen","family":"Kreiss","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandr B","family":"Stefaniak","sequence":"additional","affiliation":[{"name":"National Institute for Occupational Safety and Health, Respiratory Health Division, Morgantown, WV, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2019,9,4]]},"reference":[{"key":"2021031614493651700_CIT0001","doi-asserted-by":"crossref","first-page":"781","DOI":"10.1080\/15459624.2014.919392","article-title":"Migration of beryllium via multiple exposure pathways among work processes in four different facilities","volume":"11","author":"Armstrong","year":"2014","journal-title":"J Occup Environ Hyg"},{"key":"2021031614493651700_CIT0002","doi-asserted-by":"crossref","first-page":"505","DOI":"10.1097\/JOM.0b013e3181d6c338","article-title":"Evaluation of a preventive program to reduce sensitization at a beryllium metal, oxide, and alloy production plant","volume":"52","author":"Bailey","year":"2010","journal-title":"J Occup Environ Med"},{"key":"2021031614493651700_CIT0003","doi-asserted-by":"crossref","first-page":"e34","DOI":"10.1164\/rccm.201409-1722ST","article-title":"An official American Thoracic Society statement: diagnosis and management of beryllium sensitivity and chronic beryllium disease","volume":"190","author":"Balmes","year":"2014","journal-title":"Am J Respir Crit Care Med"},{"key":"2021031614493651700_CIT0004","article-title":"A strategy for assessing and managing occupational exposures. 3rd edn.
