Beryllium is an important metal that is used in a number of industries-including the defense, aerospace, automotive, medical, and electronics industries-because of its exceptional strength, stability, and heat-absorbing capability. It is found in a variety of technologies, including nuclear devices, satellite systems, missile systems, radar systems, bushings and bearings in aircraft and heavy machinery, x-ray machines used for mammography, cellular telephone components, computer components, and connectors for fiber optics. To help determine the steps necessary to protect its workforce from the adverse effects of exposure to beryllium used in military aerospace applications, the U.S. Air Force requested that the National Research Council's Committee on Toxicology (COT) conduct an independent evaluation of the scientific literature on beryllium, provide risk estimates for cancer and noncancer health end points, and make recommendations about specific tests for surveillance and biomonitoring of workers. The request specified that two reports be produced to accomplish those tasks. The first is to provide a review of the scientific literature on beryllium, and the second will expand more critically on the review in considering the maximum chronic inhalation exposure levels that are unlikely to produce adverse health effects, in estimating carcinogenic risks, and in providing guidance on testing methods for surveillance and monitoring of worker populations and other specific issues detailed in the statement of task. In response to the U.S. Air Force request, COT convened the Committee on Beryllium Alloy Exposures, which prepared this first report. Health Effects of Beryllium Exposure : A Literature Review identifies the available toxicologic, epidemiologic, and other literature on beryllium that is most relevant for addressing the statement of task, focusing primarily on beryllium sensitization, CBD, and cancer.

Occupational Exposure to Beryllium (US Occupational Safety and Health Administration Regulation) (OSHA) (2018 Edition) The Law Library presents the complete text of the Occupational Exposure to Beryllium (US Occupational Safety and Health Administration Regulation) (OSHA) (2018 Edition). Updated as of May 29, 2018 The Occupational Safety and Health Administration (OSHA) is amending its existing standards for occupational exposure to beryllium and beryllium compounds. OSHA has determined that employees exposed to beryllium at the previous permissible exposure limits face a significant risk of material impairment to their health. The evidence in the record for this rulemaking indicates that workers exposed to beryllium are at increased risk of developing chronic beryllium disease and lung cancer. This final rule establishes new permissible exposure limits of 0.2 micrograms of beryllium per cubic meter of air (0.2 μg/m 3) as an 8-hour time-weighted average and 2.0 μg/m 3 as a short-term exposure limit determined over a sampling period of 15 minutes. It also includes other provisions to protect employees, such as requirements for exposure assessment, methods for controlling exposure, respiratory protection, personal protective clothing and equipment, housekeeping, medical surveillance, hazard communication, and recordkeeping. This book contains: - The complete text of the Occupational Exposure to Beryllium (US Occupational Safety and Health Administration Regulation) (OSHA) (2018 Edition) - A table of contents with the page number of each section

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.
