Chronic Beryllium Disease Prevention Program
OSHA promulgated a STEL of 2.0 μg/m 3, as measured over a 15-minute sampling period, to help reduce the risk of beryllium sensitization (BeS) and chronic beryllium disease (CBD) in beryllium-exposed workers. OSHA also adopted an action level for airborne beryllium of 0.1 μg/m 3, calculated as an 8-hour TWA.Web

Most exposures to beryllium that cause disease are related to beryllium processing. The major route of human exposure is through airborne particles of beryllium metal, alloys, oxides, and ceramics. Beryllium particles are inhaled into the lungs and upper respiratory tract. Hand-to-mouth exposures and skin contact with ultrafine particles can ...Web

Abstract. Exposure to beryllium remains a significant occupational hazard, clinically resulting in berylliosis, or chronic beryllium disease (CBD). This scarring lung disease is an interstitial lung disease characterized by granulomatous inflammation that affects 2–10% of those exposed. Serving as a model for other granulomatous disease, …Web
