WebPhosphorus pentafluoride is irritating to eyes and skin and can cause severe eye and skin burns. It may cause permanent eye or skin injury. Contact with compressed gas may cause cold burns or frost bite. Extended low level systemic absorption of fluorides may cause fluorosis, an abnormal calcification of the skeletal system.
