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.

Book Description
Surface Contamination presents the proceedings of first International Symposium on Surface Contamination, held at Gatlinburg, Tennessee in June 1964. The meeting discusses the potential hazards brought about by noxious contaminants on surfaces; the effects of contamination to human health and safety; and the integrity of scientific and technical machinery and products in meeting the exacting requirements. The book contains the work of experts from different technical and administrative disciplines. Areas covered include fundamental research on redispersible and evaporable contamination, including radioactive, biological, chemical, and abrasive contaminants. Administrative and technical problems on radioactive surface contamination control criteria; measurement techniques; environmental control of surface contamination; dissemination of airborne microorganisms; radioactive contamination control applications; biological and chemical surface contamination; insurance and economics; and decontamination are tackled as well. The text will be a good source of information for ecologists, environmentalists, chemists, biologists, students, and policymakers.

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
This position paper addresses the management of beryllium contamination on legacy waste. The goal of the beryllium management program is to protect human health and the environment by preventing the release of beryllium through controlling surface contamination. Studies have shown by controlling beryllium surface contamination, potential airborne contamination is reduced or eliminated. Although there are areas in Building 9201-5 that are contaminated with radioactive materials and mercury, only beryllium contamination is addressed in this management plan. The overall goal of this initiative is the compliant packaging and disposal of beryllium waste from the 9201-5 Legacy Material Removal (LMR) Project to ensure that beryllium surface contamination and any potential airborne release of beryllium is controlled to levels as low as practicable in accordance with 10 CFR 850.25.

Book Description
Beryllium is a lightweight metal that is used for its exceptional strength and high heat-absorbing capability. Beryllium and its alloys can be found in many important technologies in the defense and aeronautics industries, such as nuclear devices, satellite systems, radar systems, and aircraft bushings and bearings. Pulmonary disease associated with exposure to beryllium has been recognized and studied since the early 1940s, and an occupational guideline for limiting exposure to beryllium has been in place since 1949. Over the last few decades, much has been learned about chronic beryllium disease and factors that contribute to its occurrence in exposed people. Despite reduced workplace exposure, chronic beryllium disease continues to occur. Those developments have led to debates about the adequacy of the long-standing occupational exposure limit for protecting worker health. This book, requested by the U.S. Air Force to help to determine the steps necessary to protect its workforce from the effects of beryllium used in military aerospace applications, reviews the scientific literature on beryllium and outlines an exposure and disease management program for its protecting workers.
