Book Description
This research compared three wipe sampling techniques currently used to test for beryllium contamination on room and equipment surfaces in Department of Energy facilities. Efficiencies of removal of beryllium contamination from typical painted surfaces were tested by wipe sampling without a wetting agent, with water-moistened wipe materials, and by methanol-moistened wipes. Analysis indicated that methanol-moistened wipe sampling removed about twice as much beryllium/oil-film surface contamination as water-moistened wipes, which removed about twice as much residue as dry wipes. Criteria at 10 CFR 850.30 and .31 were established on unspecified wipe sampling method(s). The results of this study reveal a need to identify criteria-setting method and equivalency factors. As facilities change wipe sampling methods among the three compared in this study, these results may be useful for approximate correlations. Accurate decontamination decision-making depends on the selection of appropriate wetting agents for the types of residues and surfaces. Evidence for beryllium sensitization via skin exposure argues in favor of wipe sampling with wetting agents that provide enhanced removal efficiency such as methanol when surface contamination includes oil mist residue.

Book Description
As the use of beryllium grows worldwide, the need for a single source of information on this important but toxic element is of increasing importance. This comprehensive book describes all aspects of the current sampling and analysis techniques for trace-level beryllium in the workplace. It offers both a historical perspective and a description of the state-of-the-art in a single place. It covers the challenges inherent in sampling procedures such as reproducibility, limited sample volume, surface sampling materials and collection efficiency. It also deals with the problems involved in analytical techniques including lower detection limits, identification and compensation for matrix interferences, greater sensitivity requirements and the need for more robust preparation techniques. Future trends, including development of real-time beryllium sampling and analysis equipment, are also explored. Readers will gain an understanding of sampling and analytical techniques best suited for sensitive and accurate analysis of beryllium at ultra-trace levels in environmental and workplace samples. Many "standard" sampling and analysis techniques have weaknesses that this book will help users avoid. Written by recognized experts in the field, the book provides a single point of reference for professionals in analytical chemistry, industrial hygiene, and environmental science.

Book Description
This research project was conducted at the National Nuclear Security Administration's Kansas City Plant, operated by Honeywell Federal Manufacturing and Technologies, in conjunction with the Safety Sciences Department of Central Missouri State University, to compare relative removal efficiencies of three wipe sampling techniques currently used at Department of Energy facilities. Efficiencies of removal of beryllium contamination from typical painted surfaces were tested by wipe sampling with dry Whatman 42 filter paper, with water-moistened (Ghost Wipe) materials, and by methanol-moistened wipes. Test plates were prepared using 100 mm X 15 mm Pyrex Petri dishes with interior surfaces spray painted with a bond coat primer. To achieve uniform deposition over the test plate surface, 10 ml aliquots of solution containing 1 beryllium and 0.1 ml of metal working fluid were transferred to the test plates and subsequently evaporated. Metal working fluid was added to simulate the slight oiliness common on surfaces in metal working shops where fugitive oil mist accumulates over time. Sixteen test plates for each wipe method (dry, water, and methanol) were processed and sampled using a modification of wiping patterns recommended by OSHA Method 125G. Laboratory and statistical analysis showed that methanol-moistened wipe sampling removed significantly more (about twice as much) beryllium/oil-film surface contamination as water-moistened wipes (p

Book Description
Occupational factors are responsible for a large percentage of cases of asthma in adults of working age. Any irritant generated at high concentrations can cause occupational asthma, and early diagnosis is critical because cure is still possible at this stage. This latest edition of Asthma in the Workplace reflects the rapid pace of discovery and research in workplace asthma that has taken place in recent years. This Fourth Edition retains the international flavor of prior editions, with contributions from editors and contributors from around the world. Several chapters commence with clinical histories and workplace scenarios relevant to the focus of the chapter, making it particularly germane for primary care providers to develop skills in early recognition of the disease. Topics discussed include: Definitions, historical background, epidemiology, genetics, pathophysiology, and animal models Guidelines for assessing the worker and the workplace, and proposed guidelines for management, including compensation aspects Medicolegal aspects, prevention, and surveillance Detailed information about specific agents, including a variety of high- and low-molecular weight agents Other types of work-related asthma conditions, such as irritant-induced asthma, eosinophilic bronchitis, and occupational rhinitis This new edition has been significantly restructured and places a greater emphasis on the clinical aspects of management and treatment. This heightened focus on practical considerations makes it a truly comprehensive, hands-on resource for practitioners and researchers in this fast-moving field.

Book Description
It has been suggested that beryllium can enter through either intact skin or breaks in the skin to initiate sensitization. Therefore, it is essential that all possible pathways of exposure be considered when assessing a work site for potential exposure to beryllium. A meta-analysis was done on the data from eight different industries that use beryllium or beryllium alloys, which were surveyed by Occupational Safety and Health Administration contractors, with reports being issued. During those visits, measurements were made to characterize worker exposure to skin and surface contamination levels of beryllium. Surface contamination evaluation followed the well-established protocol for lead surface contamination measurements using NIOSH Method 9100 and hand contamination using NIOSH Method 9102. It was found that both the arithmetic and geometric means of the surface samples were significantly higher in work areas as compared to administrative areas. Skin samples were also higher for individuals in production areas than for those in non-production areas. If skin contamination is a route of sensitization, these results would mean that past studies of beryllium exposure and subsequent disease might have been confounded by the lack of skin exposure data.
