Causes eye irritation. May cause skin irritation. May be harmful if swallowed.

Potential health effects

of Overexposure Eye Contact: Flakes may cause slight eye irritation. Dusts may cause severe irritation with corneal injury. Effects may be slow to heal. When dissolving, the heat produced may cause more intense effects as well as thermal burns. Skin Contact: Brief contact is essentially nonirritating to skin. Prolonged or repeated exposure may cause skin irritation, even a burn. Prolonged skin contact is unlikely to result in absorption of harmful amounts. Not classified as a corrosive to the skin according to DOT guidelines. May cause more severe response if continued to skin or skin is abraded (scratched or cut). When dissolving, the heat produced may cause more intense effects as well as thermal burns. Inhalation: Dust may cause irritation to upper respiratory tract (nose and throat). Vapors are unlikely due to physical properties. Ingestion: Low toxicity if swallowed. Swallowing may result in irritation to the mouth, throat and gastrointestinal tract. Small amounts swallowed incidental to normal handling operations are not likely to cause injury; however, swallowing large may cause injury.
