Safety Profile
Confirmed carcinogen. Cases of berylliosis have been reported from exposure to so-called low beryllium alloys. Human systemic effects by inhalation: dyspnea, fibrosing alveolitis, weight loss, or decreased weight gain. See also BERYLLIUM COMPOUNDS and COPPER COMPOUNDS. When Copper alloy, Cu,Be (CAS NO.11133-98-5) is heated to decomposition, it emits very toxic fumes of BeO.
