Beryllium is a hazard to worker health and safety; OSHA estimates that 62,000 workers are potentially exposed to beryllium every year. Its primary risks are berylliosis, a chronic lung disease, and lung cancer. Acute beryllium poisoning, a respiratory disease formerly common in industry, is now rare due to modern exposure standards.

Petition to OSHA to Lower Occupational Exposure to Beryllium

Beryllium exposure occurs when, in the process of producing these items, beryllium is ground, sanded or cut, producing a fine dust or fume that can be inhaled. There is some evidence that machinists are at particularly high risk, perhaps because they are exposed to smaller particles that can reach the deepest recesses of the lung.

Beryllium sensitization (BeS) is found in 1% to 16% of beryllium workers with known exposures to insoluble forms of beryllium. A sensitized worker is one who has developed an allergic reaction to beryllium. A worker may become sensitized at any point when there has been exposure to beryllium metals, oxides or other insoluble beryllium materials.
