Federal Register :: Occupational Exposure to Beryllium

Occupational exposure to beryllium can also occur from skin, eye, and mucous membrane contact with beryllium particulate or solutions including deficiencies in the study design, improper administration of beryllium test compounds, and lack of proper controls (Document ID 1793) In addition, Strupp (2011a) omitted numerous key animal and Beryllium Testing | Department of Energy,Exposure to beryllium and certain beryllium compounds can result in beryllium sensitization, which may develop into a disease of the lungs called chronic beryllium disease (CBD) Beryllium sensitization is an "allergic" condition to beryllium that can develop primarily after a person breathes air containing beryllium mists, dusts, and fumesCDC - Beryllium Processors (Beryllium) - NIOSH Study Summary,The amount of exposure to beryllium (the dose) plays a role in the development and severity of the disease However, sensitization (an allergy-type reaction) to beryllium is a major factor Hence, a small number of people will develop chronic beryllium disease even with minimal beryllium exposure
