Has a distinct smell
-shortness of breath

-loss of appetite
• A study of 689 patients(421 men) with
beryllium disease consisted of 28 deaths from
– Adjustments of smoking did not make a difference
– A point later was made that one was more
pronounced with acute disease than among those
with chronic disease.
• Construction workers at Department of Energy
• less than 1% have been found to have CBD.
•Machinists in beryllium operations
•10 to 14% of the workers have gotten chronic beryllium disease.
• No cure for chronic beryllium disease.
• Treatment is available that can help slow the
progression of the disease
Use/work in areas which are as ventilated as possible
Work with non-beryllium metals, alloys, ceramics and salts.
Do not eat, drink or smoke in areas where beryllium is in use.
Before entering work areas where beryllium is used, change
into work clothes, including shirt, pants and shoes.
At the end of the work shift take a shower and thoroughly
clean your hands and hair before changing into street clothing.
Use respirators for tasks that result in higher exposures.
Cases of chronic berylliosis were first described in 1946 among workers in plants
manufacturing fluorescent lamps in Massachusetts. Chronic berylliosis resembles
sarcoidosis in many respects, and the differential diagnosis is often difficult. It
occasionally killed early workers in nuclear weapons design, such as Herbert
A new case of chronic beryllium disease is described, occurring in a 33-year-old man
who had worked with beryllium alloys in 1961. Weight loss and muscle pains were the
main clinical features while radiological changes were minor. Serial lung function
studies showed improvement after corticosteroids, but impairment of gas transfer
• Beryllium is the lightest alkaline earth metal
• The element beryllium is rare in the universe because
beryllium was created by the Big Bang and is not typically
formed by the nucleosynthesis reactions of stars.
• The name originates from the Greek word beryllos meaning
• Beryllium was discovered in France by Nicolas-Louis
Vauquelin in beryl and in emeralds in 1798 and was isolated
as the metal independently by Friedrich Wöhler and A.A.
Bussy in 1828.
