The National Institute for Occupational Safety and Health (NIOSH), working under an interagency agreement with the Office of Regulatory Analysis of the Occupational Safety and Health Administration (OSHA), conducted a study of occupational exposures in secondary beryllium processing facilities to document engineering controls and work practices affecting those exposures. The performance of a thorough industrial hygiene survey for a variety of individual employers provides valuable and useful information to the public and employers in the industries included in the work. The principal objectives of this study were: 1. To measure full-shift, personal breathing zone exposures to metals including beryllium, cadmium and lead. 2. To evaluate contamination of surfaces in the work areas that could create dermal exposures or allow re-entrainment of metals into the air. 3. To identify and describe the control technology and work practices in use in operations associated with occupational exposures to beryllium, as well as to determine additional controls, work practices, substitute materials, or technology that can further reduce occupational beryllium exposures. 4. To evaluate the use of personal protective equipment in these facilities. 5. To determine the size distribution of airborne particles. An initial walk-through evaluation was conducted in August 2006, to observe processes and conditions in order to prepare for subsequent testing. An in-depth evaluation was conducted May 14 to 16, 2007, by NIOSH researchers from the Engineering and Physical Hazards Branch, Division of Applied Research and Technology, Cincinnati, Ohio. During this evaluation, two full shifts of environmental monitoring were conducted for the duration of normal plant operations.
