Beryllium copper (BeCu), also known as copper beryllium (CuBe), beryllium bronze, and spring copper, is a copper alloy with 0.5–3% beryllium. [1] Copper beryllium alloys are often used because of their high strength and good conductivity of both heat and electricity. [ 2 ]
Relevant occupations are those where beryllium is mined, processed or converted into metal alloys, or where machining of metals containing beryllium or recycling of scrap alloys occurs. [5] Metallographic preparation equipment and laboratory work surfaces must be damp-wiped occasionally to inhibit buildup of particles.
Beryllium poisoning is poisoning by the toxic effects of beryllium, or more usually its compounds. It takes two forms: Acute beryllium poisoning, usually as a result of exposure to soluble beryllium salts; Chronic beryllium disease (CBD) or berylliosis, usually as a result of long-term exposure to beryllium oxide usually caused by inhalation.
Sep. 27—Eight electrical workers recently were exposed to toxic beryllium dust while removing ceiling tiles in a building at Los Alamos National Laboratory, the latest incident in a hazard the ...
Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or inconsequential, depending on the application.
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain ...
At that time, most construction trades and industries were unaware of the potential risks associated with beryllium exposure. [42] It occasionally killed early workers in nuclear weapons design, such as Herbert L. Anderson. [43] The physicist W. W. Hansen who was instrumental in the development of the klystron also died of the disease in 1949.
The OSHA definition is part of a legal standard, which is the minimum legal requirement. Users or employers are encouraged to apply proper judgment to avoid taking unnecessary risks, even if the only immediate hazard is "reversible", such as temporary pain, disorientation, nausea, or non-toxic contamination.
