This site provides employers and workers with information on the beryllium standards, health effects of beryllium, and exposure evaluation and controls. Guidance and navigation systems manufacturing. The average time from first beryllium exposure to the development of symptoms (latency period) of CBD is 10 to 15 years. CBD has symptoms of inflammatory masses or nodules in tissues or organs and scarring of the lung tissues. In contrast, chronic beryllium disease occurs in work settings in which exposure to poorly soluble and persistent beryllium compounds predominate, such as beryllium metal, oxide, and hydroxide. Chronic Beryllium Disease. Agency for Toxic Substance and Disease Registration, Agency for Toxic Substances and Disease Registry, U.S. Department of Health & Human Services, identify the populations most heavily exposed to beryllium, and. These individuals have a risk of developing chronic beryllium disease (CBD) in the future at a rate of 6% to 8% per year (Newman et al. It is a steel-gray, strong, lightweight and brittle alkaline earth metal.It is a divalent element that occurs naturally only in combination with other elements to form minerals. The use of this test as a screening tool has improved our understanding of these health effects. Beryllium sensitization: Beryllium sensitization is the activation of the body's immune response to beryllium. Side effects of medications may also be experienced by individuals needing and receiving corticosteroids (eg, weight gain, high blood pressure, high blood sugar levels, osteoporosis) or other medications. CDC is not responsible for Section 508 compliance (accessibility) on other federal or private website. (1) Health Hazard Information Acute Effects: Acute inhalation exposure to high levels of beryllium has been observed to cause inflammation of the lungs and acute pneumonitis (reddening and swelling of the lungs) in humans; after exposure ends, these symptoms may be reversible. Emergency Responders. End products1 containing beryllium and beryllium compounds are used in many industries including: Exposure to beryllium via inhalation of airborne beryllium or skin contact with beryllium-containing dust, fume, mist, or solutions can cause health effects. In workplaces where beryllium or its alloys are present, employees should be aware of CBD. Very low concentrations of beryllium in air can cause sensitization and disease.
