| Comments |
Hydrofluoric acid formed when F5-Sb reacts with water; Corrosive to eyes, skin, and respiratory tract; Can cause acute pulmonary edema after heavy inhalation exposure; In chronic inhalation studies of animals, pneumonitis as well as liver and cardiac damage are observed. Repeated exposures to flouride compounds can result in fluorosis. [HSDB] Recent experiments show that "there is essentially very little HF formation; the substance was quite unreactive in water."
