| hazards summary | The basis for the TLV for inorganic borate compounds is irritation of the nose and respiratory tract. Studies of workers exposed to sodium borate dusts found no evidence of pulmonary function or reproductive impairment. Borate dust is moderately irritating to the skin, but it is not absorbed well by intact skin. Inhalation of borate dust can cause nasal irritation, cough, and chest tightness. In high-dose reproductive studies of animals, boric acid causes testicular damage and fetal loss. |
