Health Hazards Associated with Beryllium Typical health hazards associated with Be exposures are mainly to lung and are classified as chronic or acute beryllium ... establishing pilot plant for production of sintered Beryllium The notion behind adoption of 2.0 μg/m3 was based on the fact that during 1950s, ...

For lung cancer, there was an association with period of hire in soluble/mixed beryllium plants but not in insoluble plants, and, conversely, employment in soluble/mixed plants was associated with ...

Beryllium has also been shown to cause bone cancer in rabbits. The conclusion is also supported by findings suggestive of excess lung cancer among beryllium production plant workers. Different beryllium compounds cause a range of skin diseases. 11 The more soluble beryllium salts cause irritant and allergic contact dermatitis. Larger …

Employers must train and inform employees covered by the Beryllium standard about beryllium hazards and the methods the employer uses to limit their exposures to those hazards. Employers must cover the cost of training and must pay employees for the time spent in training. ... Workers at fossil fuel-fired power plants may encounter beryllium in ...
