Definition

Berylliosis is lung inflammation caused by inhaling
dust or fumes that contain the metallic element beryllium.
Found in rocks, coal, soil, and volcanic dust, beryllium is
used in the aerospace industry and in many types of manufacturing.
Berylliosis occurs in both acute and chronic
forms. In some cases, appearance of the disease may be
delayed as much as 20 years after exposure to beryllium.

Description

In the 1930s, scientists discovered that beryllium
could make fluorescent light bulbs last longer. During the
following decade, the hard, grayish metal was identified
as the cause of a potentially debilitating, sometimes
deadly disease characterized by shortness of breath and
inflammation, swelling, and scarring of the lungs.

The manufacture of fluorescent light bulbs is no
longer a source of beryllium exposure, but serious health
hazards are associated with any work environment or
process in which beryllium fumes or particles become
airborne. Working with pure beryllium, beryllium compounds
(e.g. beryllium oxide), or beryllium alloys causes
occupational exposure. So do jobs involving:
