This total dust data just is not going to give us the answer of how to set an occupational exposure limit, what a

[7] We collected at least two high‐resolution (≤1‐cm sampling increments) depth profiles at each site to determine how 7 Be is distributed vertically in soil profiles. In all cases, 7 Be was undetectable beneath 3‐cm depth in the soil, and generally, 7 Be was confined

2002/10/7This study was specifically aimed to determine the levels of beryllium in environmental samples near the vicinity of the beryllium metal plant (BMP). Air particulate samples collected at the BMP site, in the non-monsoon and monsoon seasons, showed an average beryllium concentration of 0.3 and 0.1 ng m −3 respectively, where as rain water samples showed the beryllium values in the

Beryllium is another chemical that affected employees of the Rocky Flats Plant. Employees were exposed by pathway of inhalation or contact with skin. It can be in dust, fume, mist or in solutions causing negative health effect of beryllium sensitization, chronic beryllium disease (CBD), and lung cancer.

Bonding in Beryllium Clusters

Beryllium clusters provide an ideal series for exploring the evolution from discrete molecules to the metallic state. The beryllium dimer has a formal bond order of zero, but the molecule is weakly bound. In contrast, bulk-phase beryllium is a hard metal with a high melting point. Theoretical calculations indicate that the bond energies increase dramatically for Be clusters in the range =2–6

Estimating historical exposures of workers in a beryllium

Airborne beryllium exposures have been monitored since the 1940s. This study describes methods used to measure airborne beryllium concentrations and how historical measurements from a beryllium manufacturing plant were used to estimate workers' exposures in a lung cancer case-control study.

Surface wipe samples were collected from 12 munitions plant buildings that housed maintenance, production, support, and administration activities. Targeted areas included the main machine shop where beryllium alloy tools reportedly were dressed most

Beryllium-containing ores treated with conventional mineral processing techniques such as crushing, grinding, desliming, chemical activation, and flotation is discussed. Alloying, casting, powder processing, forming, metal removal, joining and other manufacturing processes are covered.

In this paper, we evaluated the airborne beryllium concentrations at a machining plant using historical industrial hygiene samples collected between 1964 and 2000. With the exception of a few projects conducted in the 1960s, it is believed that 95% of the operations used copper beryllium

Based on the expectation that worldwide stockpiles of beryllium concentrate were being depleted, Materion increased its capacity to produce beryllium hydroxide at its Delta plant in 2013 and, in 2015, invested $23 million to further develop its bertrandite pits in

Flats Plant. Beryllium exposure was assessed via fixed airhead (FAH) sampling in which the filter cassette was affixed to the machine, generally within a few feet of the worker's breathing zone. Approximately 500,000 FAH samples were collected for beryllium

OSHA has cited Prestress Services Industries of Ohio LLC for 20 safety and health violations at the concrete production plant in Mount Vernon, Ohio. The company faces penalties of $158,555. Inspectors determined that noise levels in the plant were above the permissible exposure limit, and that the company failed to train, test, monitor, and provide medical surveillance for employees exposed to
