Beryllium Laboratory Analysis "Laboratory selection is a key thing," said Michael Brisson, MS, PMP, while speaking on the topic of laboratory analysis for tracelevel beryllium in air, surface, and bulk samples.
Because beryllium resists attack by liquid sodium metal, it is employed in cooling systems of nuclear reactors that use liquid sodium as the heattransfer material; because it is a good reflector and absorber of neutrons, it is also used as a shield and as a moderator in nuclear reactors.
Definition and Characteristics. Chronic granulomatous disease primarily affecting the lungs and characterized by delayed hypersensitivity to beryllium. ... Chronic beryllium disease: T cell recognition of a metal presented by HLADP. Clin Immunol 100(1):4–14 PubMed Google Scholar. 4.
Beryllium is a very strong and lightweight metal that is used in the electronics, aerospace and nuclear power industries. Chronic beryllium disease is caused by inhalation of airborne beryllium during its processing such as in melting or grinding it.
Abstract. Clinical manifestations of interstitial lung diseases of occupational origin cover a wide spectrum and they are a moving target. They change their appearance in response to safety measures and new types of exposure.
OSHA is proposing to change or add six terms in the definitions paragraph—beryllium sensitization, beryllium work area, CBD diagnostic center, confirmed positive (regarding tests to determine beryllium sensitization), dermal contact with beryllium, and chronic beryllium disease.
Berylliosis, or chronic beryllium disease, is a chronic allergictype lung response and chronic lung disease caused by exposure to beryllium and its compounds. As an occupational lung disease, it is most classically associated with aerospace manufacturing, beryllium mining or .
Chronic beryllium disease (CBD) shares many of its characteristics with sarcoidosis and is often treated with corticosteroids. There is limited available literature regarding the effect of longterm corticosteroid therapy on the natural history of CBD.
Pneumoconioses. A group of chronic lung diseases caused by exposure to a mineral dust or a metal. The major pneumoconioses include asbestosis, silicosis, coal workers' pneumoconiosis (black lung disease), and chronic beryllium disease. Full details about asbestosis are available in a separate monograph.
Chronic beryllium disease is formed when you breathe in beryllium over a longer period of time at relatively low concentrations. In other words, imagine breathing in beryllium at a low ...
Beryllium lung disease is a chronic granulomatous disorder in which a berylliumspecific immune response plays a central role. By using a measure of cellular immune response to beryllium salts, bronchoalveolar lavage (BAL), and lung biopsy, we have identified 12 new cases of beryllium disease.
Chronic beryllium disease (CBD) is an occupational hypersensitivity disorder elicited by beryllium exposure in the workplace. It is characterised by noncaseating granuloma within affected organs, predominantly lung and skin to their attractive properties, copper, aluminium, nickel, magnesium and iron alloys containing beryllium are increasingly used in various industries and trades 2, 3.

Posted December 11, 2018. OSHA published a beryllium proposed rule for general industry in the December 11 Federal Register, which the Agency says is intended to clarify certain provisions and simplify or improve compliance.. The proposed rule adds the definition of "beryllium sensitization" and revises the definitions of "beryllium work area," "chronic beryllium disease (CBD ...
Individuals who are exposed to beryllium dust or fumes are at risk of lung cancer and a granulomatous lung disease called chronic beryllium disease (CBD) (39–43). Beryllium is atomic number 4 on the periodic table of the elements.
Beryllium associated diseases are potentially multiorgan with variable pattern and timing of onset. Their diagnosis and management depends on use of complex medical reasoning that includes inputs from a careful occupational history, interpretation of immunoassays, imaging studies, and other tests.
