Control of beryllium exposure may prevent serious or fatal lung disease.
Inhaling beryllium dust or fumes may cause a serious illness in some people. This illness is chronic beryllium disease, an irreversible and sometimes fatal scarring of the lungs. Beryllium exposure may also result in lung cancer. Workers who work with or around beryllium, beryllium alloys and beryllium-containing materials need to learn of the health risks of beryllium disease. Worker exposure to beryllium should be controlled to levels as low as possible below the regulated Occupational Exposure Limit.
Workers engaged in the production, fabrication and finishing of beryllium alloys may be exposed to dust and fume. Mining of beryl ore has not been associated with adverse health effects. Beryllium in solid form and in finished products presents no special health risks.
Uses of beryllium include: metal working (pure beryllium, copper and aluminum alloys, jet brake pads, aerospace components); ceramic manufacturing (semi-conductor chips, ignition modules, crucibles, jet engine blades, rocket covers); electronic applications (transistors, heat sinks, x-ray windows); atomic energy applications (heat shields, nuclear reactors, nuclear weapons); laboratory work (research and development, metallurgy, chemistry); extraction (ore and scrap metal); and dental alloys (crowns, bridges, dental plates); and sporting goods (golf clubs, bicycle frames).
Some of the processes and operations that may release beryllium are:
The following measures may be used to reduce beryllium exposure in the workplace:
The Regulation respecting Control of Exposure to Biological or Chemical Agents [R.R.O. 1990, Reg. 833,] sets an Occupational Exposure Limit requiring employers to limit the exposure of workers to beryllium and its compounds to the value set out in Table 1 of the Regulation.
